Tech Report: DLAA Used In SW:Force Unleashed II

Nowadays it seems like everyone is experimenting with various forms of anti-aliasing. Titles such as MGS4, DMC4, and Halo Reach use a form of temporal AA - edge smoothing which works by blending two frames together to eliminate jaggies, whilst others like God Of War 3 and Little Big Planet 2 use morpthalogical AA, a method that works on depth buffers and individual pixels in each frame resulting in up to 16xMSAA on some surfaces, and 4x on most. Now LucasArts are joining the club with their latest Star Wars action game.

In Star Wars: The Force Unleashed 2, the developers are using something called Directionally Localized Anti-Aliasing (DLAA), which looks to be similar to MLAA in its effects and implementation, though it appears to work on a directional, positional type basis (possibly multiple frame) leading to some undesirable artefacts in motion.

The tech is undeniably impressive, and the 360 demo showcases what looks like being the most accomplished form of AA on the platform so far, regardless of a few noticeable shortcomings.

The screenshots below (thanks IGN) show the DLAA working under somewhat ideal conditions, with very little in the way of inconsistant, fast-paced movement present in the scene. Notice how clean looking the entire image is. There’s very little, to no aliasing at all, and even smaller pixels get smoothened over successfully.



Unfortunitely, due to the way this form of AA seems to work, in scenes with quick camera pans, and fast moving objects there is noticeable artifacting. This also seems to be the case when directionality and positioning of the light sources in the scene change in accordance with the action. When this happens not all surfaces get AA, with some missing out on edge smoothing almost entirely.

The artifacting caused by the AA in these screens is also joined by other undesired side effects from the game’s use of motion blur, which tends to accentuate the overall amount of artifacting in the scene. However, it is also hard to tell whether it is just the AA causing problems, the motion blur, or a combination of both.

You can see this below:




Either way the use of DLAA in SWFU2 is very impressive, though not faultless, and has a very similar effect to MLAA with regards to edge smoothing. It’s not quite as polished, or a beautifully clean as MLAA however, although it does provide a workable alternative to traditional 2x and 4xMSAA at a lesser cost.

A high quality implementation of SSAO is also visible in the screenshots, and in the actual demo. There’s minimal artifacting, and a nice amount of additional depth.

And another thing. Despite being released by the press, these screens certainly are not bullshots - the demo available on the Xbox Live looks exactly the same. SWFU2 renders in 1280x720p on the 360 at least, with DLAA providing the high quality edge smoothing on offer here.

This is the first time that any developer has attempted this type of AA on the Xbox 360, and the results are very impressive, and the outlook positively optimistic. The use of alternative, less memory intensive forms of edge smoothing could easily have a beneficial effect on use of the 360’s EDRAM for other rendering tasks, freeing it up for developers to use on improving other graphical areas in the pipeline, pushing the boundaries of the hardware further than initially thought possible. But until then, this is a firm shift in the right direction.

DLAA is also being used in the PS3 build of the game (implemented on the SPU’s) and on the PC (on the GPU), although we haven’t had a chance to try either version out. But I imagine that overall image quality should be the same, assuming identical rendering resolutions and alpha buffers for effects.

Thanks go out to AlStrong for counting those pixels, and IGN for the screens.

Tech Analysis: Sonic Adventure (PS3 & 360)

I have many fond memories of the original Sonic Adventure on the Dreamcast, so much so that I thought I’d invest in a copy of the recent PSN and XBL HD re-release of this Sega classic. Mainly for fun at first. Although that fun quickly turned into investigating just how well this HD revision holds up for the latest IQGamer Tech Analysis.

On first impressions it looks like Sega has taken the liberty of porting and sprucing up the original DC version of the game. However, on closer inspection it is clear that this re-release is a bizarre combination of the GCN version of the game (Sonic Adventure DX), minus the extra content, with the DC original’s title screen tagged onto the end of it.

For those of you who don’t know, Sonic Adventure DX featured a few graphical upgrades over the DC game, including specular highlighting on Sonic and the other main characters, reworked texturing, and a boost in overall framerate. And this is exactly what we get here, but with some additional tweaks and changes. Unfortunately, the DX version also features far more in the way of potentially game-breaking collision glitches, and sloppy control issues, neither of which felt quite as bad in the standard DC game.


The first thing you’ll notice, is that Sonic Adventure comes in a bordered 4:3 aspect ratio, with thick stripy bars on each side of the screen, and thin ones at the top and bottom. While the overall output resolution of the framebuffer is in fact 720p (1280x720) the gameplay segment itself is presented in 920x690, being 1:1 mapped to ensure that the image isn’t being cut off.

Interestingly, the final output looks somewhat blurrier than what a 690p image would look like when occupying its space in a native 720p framebuffer. Instead we can see that the game is actually rendering in 480p, and then being upscaled to 690p to form the final displayed frame. It’s not rendering in bordered HD that’s for sure.

The difference between what the game looks like when running in native 720p can be found below. The top screen shows the PC version running in true HD resolution, while the bottom shows the PSN and XBLA version upscaled to 690p.


PC


PS3 & 360

Without doubt this has to be one of the most disappointing aspects of the port, rendering in SD, and is an indication of just how much of a rush job to market it initially appears to be. When you consider that both the 360 and PS3 could easily handle the PC version of Sonic Adventure DX running in 720p, and at 60fps, then it is a mildly bitter pill to swallow, and a worrying sign for future DC conversions.

Saying that the upscaling method itself is very good - better than we've seen on some full price titles - and although this PSN and XBLA re-release doesn’t use any form of anti-aliasing, the game looks reasonably smooth, being free of most harsh jagged lines and polygon edges.

So, with no AA being present the smooth look can instead be attributed to the game’s poor use of bilinear texture filtering, and blurred nature due to the framebuffer being upscaled, both of which affect final image quality heavily. In still screens the lack of AA is more easily noticeable, though that doesn’t always appear to be the case in motion.

Thankfully, resolution isn’t everything, and most of the enhanced visual effects introduced in the GCN version of the game have been included here; additional specular highlighting, greater use of defuse mapping, and texturing changes are all brought to the table.


PC


DC

Above you can see the changes between the DC and PC versions of the game. These also apply to the PSN and XBLA releases too, and give you an idea of the differences between SA DX and vanilla SA.

However, both the PSN and XBLA builds of the game also feature improved shadowing on the characters as well. This can be seen on Sonic’s mouth and belly in the screenshot below, and looks pretty odd in motion, seeming a little overblown and unnatural.


Unusually, this version of Sonic Adventure lacks the inclusion of the reflective water found in the GCN build, but still features the same updated texturing. Oddly, this is also apparent in the PC game, a telltale sign that highlights which code was used for the PS3 and 360 ports.

Outside of these slight differences, nothing else appears to have changed. The art assets used are definitely the updated GCN ones, and in some cases look a tad blurrier, or less detailed than some of the ones used in the original DC game. The sheen on Sonic in particular is unnecessary, and some of the texturing now looks murky and undefined. However, many textures actually benefit from being replaced with higher-res versions, and look much better than the ones used in the original DC game. Though these improvements are largely under-represented due to the upscaled nature of the final image distorting things somewhat.


One area in which the PS3 and 360 versions of Sonic Adventure have seen the biggest gains, is with regards to performance. It’s nice to finally see a version of the game running largely as originally intended with only a few dips in fluidity intruding on the action.

Sonic Adventure runs at a near constant 60fps for 99.9 percent of the time, and the difference is instantly noticeable. I only encountered the odd drop down to 30fps, which lasted only for a brief second or so, maybe less. Apparently, in the 360 version these little dips happen slightly more frequently. However, I can’t confirm this for sure as I only own the full PS3 game, and the 360 demo, but not the full retail release.

For those of you who don’t know, early demos and pre-release builds of SA on the Dreamcast ran at 60fps with frequent drops in framerate, often down to 30fps. However, the final game runs at 30fps, with heavy bouts of slowdown to 20fps in the most detailed areas. Many parts of the Lost World stage saw the game holding a near constant 20fps, before narrowly getting back up to the 30 mark.

By contrast the GCN DX port managed to hit 60fps pretty much all the way through the entire game, with regular and sometimes random drops to 30, sometimes even 20fps, regardless of whether or not detail levels were significantly higher. In particular, the game often juddered between fluctuating framerates, sometimes hitting the target 60fps for extended periods of time, sometimes not.

Going back to the PS3 and 360 ports, and rather bizarrely, SA’s cut-scenes completely side step the upgrade to 60fps altogether, and are delivered with a fifty percent cut in smoothness compared to the standard during gameplay. The in-engine cinematics are all locked at 30fps, with no real reasoning as to why this was done. It’s not as if these parts of the game would prove more difficult to optimise, since the rendering load does not change at the drop of a hat like in gameplay (it can be controlled and is utterly predictable), then if anything, guaranteed performance at 60fps should be easier to obtain.

Like with the upscaled nature of the game’s framebuffer resolution, it appears that the developers have simply been rather lazy, performing optimisations on the most obvious parts of the game, whilst leaving others almost completely untouched. What is stranger still, is that the addition of improveved shadowing can be seen in both the cut-scenes and the gameplay, meaning that some tweaks were in fact made to both the engine, and entire game as a whole.

As expected, SA is fully v-synced on both platforms and never so much as tears a single frame. Of course this was the case on both the DC and GCN, but is an increasing rarity with titles this generation. Either way it’s nice to see a title not only hitting its target framerate but also doing that without tearing frames. Although, for an even year-old game running on a current gen platform, in 640x480 no less, you should expect nothing less, especially in lieu of any major (or barely even minor) graphical upgrades.


All things considered, whilst the PS3 and Xbox 360 versions of Sonic Adventure aren’t exactly great ports overall, they are redeemable in some respects, and the upgrade to 60fps is both pleasing on the eye and beneficial to the controls. Sonic himself is far more responsive, and the flow of the action is better represented than ever before.

However, the conversion also reeks of laziness through and through. The lack of any kind of widescreen support, or even the option to change the colour of the border surrounding the gameplay is unacceptable in this day and age. And the absence of a true 720p HD presentation is baffling to say the least.

Outside of that, the use of the DX code means that there are more gameplay glitches than in the Dreamcast original, with characters getting stuck in scenery, and odd collision detection errors being quite commonplace - things that arguably should have been sorted out given the high-profile nature of the release.

In conclusion then, the PS3 and 360 release of Sonic Adventure is still perhaps one of the best versions of the game we’ve seen so far, even if it doesn’t quite play as well as the DC original. Seeing, and ‘feeling’ it running in 60fps makes it well worth a look despite the obvious criticisms. Although, at the same time one can’t help but feel somewhat cheated considering both consoles could quite easily handle a full 1080p60 port without breaking sweat.

Tech Analysis: Enslaved Demo (360 vs PS3)

When most people talk about the PS3’s unique architecture and the games which really show off the machine’s graphical prowess, both Uncharted 1&2 often crop up, as do Killzone 2 and God Of War 3. However, many seem to have forgotten about Heavenly Sword. Because during a time when HDR lighting and anti-aliasing were thought near impossible to do on the PS3’s NVIDIA 7800 derivative GPU in combination, Ninja Theory’s cinematic action game was doing just that.

At the time using a custom HDR format known as LogLuv (NAO32) allowed the developers to include full range HDR lighting whilst also adding proper 2x multi-sampling anti-aliasing support into the mix. Combined with highly detailed texturing, advanced facial animation and complex character modelling, Heavenly Sword still holds up well today, and is the culmination of a collaboration between NT and other Sony studios in sharing technology to improve PS3 development.

Enslaved shares similar traits to that title. The game takes on a deeply filmic tone, cinematic in its execution, while the gameplay features slightly delayed response times with regards to the controls, and canned animations to keep the feel of an interactive move at the forefront of the experience. This is all backed up by superb voice work by Andy Serkis (who also did Heavenly Sword) and a solid script from Alex Garland, writer of the Beach and 28 Days Later.

However, there are a few differences between Enslaved and Heavenly Sword. The former was simply a PS3 exclusive, designed to get the most out of Sony’s machine in order to have a strong third-party offering for the format. Enslaved however, is a multiplatform release appearing on both PS3 and 360.

With this change of direction comes a change in game engine. Rather than to try and port over the tech powering their last effort, Ninja Theory has opted to use the Unreal Engine 3 for Enslaved. A common choice amongst third-party developers, it usually tends to favour the 360 as its lead platform with the PS3 often on the receiving end of some less than stellar conversions. Lower framerates, an abundance of screen tearing, and lower rendering resolutions are normal issues the PS3 faces with games using the engine.

That said, UE3 also provides a powerful, more familiar development environment in which to work on. And for Enslaved that is exactly why Ninja Theory decided to choose the engine over and above porting across their custom approach powering Heavenly Sword. But unlike other most other titles that use it, Enslaved manages to scrub up incredibly well on both platforms, almost hitting parity on the PS3. Apart from having one of two lower res / scaled back effects, and lower overall performance, both versions aren’t far off from being identical.


Most of the time with titles using UE3, it is common to find a discrepancy between the framebuffer resolution on one platform and on another. However, you’ll be pleased to know that Enslaved renders in 720p (1280x720) on both 360 and the PS3, with the game appearing identical in this regard.

Unlike Singularity, and both Gears Of War 1&2 on the 360, neither version of Enslaved features the standard selective 2xMSAA anti-aliasing solution used in most UE3 titles. Instead both versions lack AA altogether, and maintain similar levels of sharpness to each other.

Although, this isn’t quite as bad as it first sounds, seeing as the selective AA favoured by the engine usually has very little impact in real world terms. In still screenshots there is a noticeable, but slight improvement in overall image quality. However, this is simply restricted to either static objects, or the whole scene if nothing is moving. So in effect, most of the time you get practically no AA coverage anyway, thus making its inclusion of little worth when you consider the marginal gains on offer.

That said, even with a lack of AA Enslaved is hardly a jagged mess, and most of the harsher polygon edges are smoothened out by the game use of a stylish post process motion blur effect, and a little bloom lighting, which in effect negates the need for the jaggies reduction provided by 2xMSAA.


Although the inclusion of motion blur in Enslaved is mainly there for cinematic purposes. It also makes the whole experience take on a more cinematic tone, reproducing the camera blur present in fast action sequences found in movies.

A side effect of the blur is that it gives an impression of making the game seem smoother than it actually is. Usually this is done to make a 30fps experience flow slightly more like one that is perhaps running at 45fps, but obviously without truly achieving this. It’s a nice but subtle illusion, and in Enslaved it helps to briefly hide some of the game’s smaller drops in framerate. Though not the heavier ones, in which case there is nothing it can do.

As mentioned earlier the use of motion blur also has the effect of smoothening out jagged lines caused by the game’s lack of AA. The 360 version benefits the most, looking slightly smoother than the PS3 game. Albeit subtly so.

The reason for this, is that the use of the motion blur has been paired back on the PS3 build. It is clearly stronger on the 360 game, helping to deliver a slightly cleaner and more filmic look to the proceedings. Although, the difference is far less noticeable in motion than it is in the still screens featured on this page.

You may also notice that sometimes the PS3 version is missing blur entirely. This only tends to happen when use of the effect is so subtle that the engine doesn’t even activate it on the PS3, where it is cut down anyway. The result is that some scenes benefit from it, while others don’t.



Another area in which the 360 sees a handful of subtle graphical improvements, is with regards to the resolution of certain visual effects. Things like smoke, electricity, and certain lighting and particle effects are rendered in a lower resolution on the PS3. The two screenshots above show just how close both versions are; some effects like the electric power staff have harsher edges on the PS3 and appear slightly more aliased in motion, whilst the light coming through the ship on the right hand-side appears slightly softer owing to both seeing a reduction in resolution.

However, the differences are very subtle and hard to spot when playing the game, if not occasionally impossible. They certainly don’t take anything away from the PS3 build at all, instead showing that slight compromises don’t always lead to detrimental impact on overall graphical quality.


In terms of lighting and shadowing both are virtually identical as well. The 360 build gets a slight increase in bloom lighting, making hard polygon edges look smoother – much like the use of motion blur, the effect helps in reducing overall scene aliasing - whereas PS3 owners get a reduced version of the same thing featuring less image smoothing properties.


The shadowing model is reasonably accomplished, though somewhat basic compared to the likes of Uncharted 2, or even Bioshock 2 - that’s to say it has an effect of making parts of the game look very flat at times. In particular, with half of the objects in daylight scenes being covered by shadows, there is little depth to be had in these darkened parts of the environment. Instead, the only time in which the game really delivers a direct, noticeable sense of depth is with high contrasting light and dark areas.


Changing the intensity of the different light sources found in the game, along with expanding the range of colour provided by them would go a along way in circumventing this. As it stands the shadowing lacks a decent amount of tonal variations, and differing light values to do this. Neither PS3 nor 360 benefit from featuring any improvements or downgrades in this area, though the PS3’s shadowing looks slightly different from the way it is implemented on the 360, but not necessarily looking worse because of it.


Outside of the lighting and effects differences, for the most part, Enslaved actually looks identical across both platforms – a stark contrast to say, Bioshock 2, which had severe cuts made to its alpha buffer (effects) resolution, and an intrusive blur filter placed over the entire screen. Much like Singularity, the developers have done a rather good job in achieving parity on this front.

Ninja Theory have managed to get both texture detail and filtering looking mostly like for like across both versions, with the PS3 build in particular not suffering from lower res texturing than the 360 game, or gaining the usual bump in anisotropic filtering found in most titles running on the platform. It is definitely one of the better examples of multiplatform UE3 engine development, in which most changes don’t adversely affect either version in any significant way.

The same cannot be said in terms of overall performance though, in which we see the 360 build carving out a lead over the PS3 game. However, this is mostly apparent when playing each version one after the other, and not so much so when played on their own in a stand-alone fashion.


With Enslaved, the developers are clearly aiming to maintain a consistent 30fps throughout. And like with most titles using the unreal engine, the game regularly toggles between dropping framerate and losing v-sync in order to achieve that target. In this regard the 360 build fares better than the PS3 one. As we’ve seen before with Singularity, the UE3 engine appears to be more suited to Micrososft’s platform with less in the way of constant framerate drops happening, and definitely a lot less screen tearing.

The 360 version of Enslaved seems to take the most balanced approach between strictly maintaining v-sync whilst losing framerate, and dropping it ever so briefly in order to preserve it. Effectively this means that the overall amount of screen tearing taking place is regularly kept in check, with just a few small occurrences relatively subtle in their appearance.

By contrast the PS3 game tears more often, and when it occurs it is far more noticeable as a whole. Tearing isn’t just restricted to the top of the screen for short periods, but can be seen across the entire screen in parts. However, this only seems to happen in areas in which the engine becomes put under stress. The more stuff on screen, the more tearing that occurs, along with a larger drop in framerate. We're talking down to 24 - 20fps at times, though usually for only a few seconds at once. Most of the time the tearing is far more subtle in nature, and the PS3 version very often hits 30fps, with just smaller drops overall, before struggling in heavy load scenarios.

The 360 game also goes through a few heavy drops in framerate (mostly in cut-scenes), although it is feels more distinctly controlled, and doesn’t have the tendency to constantly tear frames when this happens. In which case we can see that the PS3 game largely isn’t v-synced at all, whereas the 360 game is, and often maintains it successfully, tearing less frames and keeping up its framerate.

However, the lack of v-sync on the PS3 version also leads to it having small additional spikes in performance over the 360 game. Some segments actually see it hit the target 30fps when the 360 build is lagging behind slightly. Though this certainly isn’t commonplace, and isn’t really a substitute for more even levels of performance.

Overall, it is clear that the 360 version performs better than the PS3 one, holding its framerate more solidly and tearing less frames. The use of v-sync can lead to heavy drops in performance, with frames being dropped significantly in parts – mainly the cut-scenes. But by and large it is manages to hit the target 30fps far more consistently than the PS3 game without suffering near constant screen tearing in places. The PS3 build may offer the occasional, slight performance advantage, but loses it with its lack of v-sync and generally more erratic framerate.

Saying that, much of the time the two can look virtually identical even when performance isn’t as good on the PS3 – especially when not going head-to-head against each other.


To be fair, despite issues with performance both versions of Enslaved are almost like for like. Other than a few lower resolution effects, and a downgrade in the usage of motion blur, most of the game looks identical across the board – that is to say that it can look lovely at times, both technically and stylistically, regardless of how it performs during gameplay.

Obviously, the same trends regarding the performance of the UE3 engine on PS3 remain; more unstable framerates and an increased amount of screen tear seem to be issues most developers haven’t been able to get around just yet. Though the gap does seem to be closing – we’re no longer looking at sub-HD UE3 PS3 ports anymore. Not for the most part anyway.

Granted, people who own both platforms should perhaps pick up the 360 version as it performs noticeably better across the board, though not in every instance. At the same time, the actual graphical differences outside of performance are so minor (motion blur aside) that there isn’t all that much in it. In fact you’d be hard-pressed to notice, and that certainly counts for something.

In conclusion Enslaved is better all-round on the 360, but is generally solid across both platforms, with pretty much no major differences outside of performance that you are likely to notice during gameplay. The use of high latency control also gives the whole game a somewhat laggy feel to it, and the fairly slow, Uncharted-like gameplay means that issues with framerate don’t tend to spoil things as much as they would do in fast-paced action titles that require far quicker reflexes.

Review: Dead Rising 2 (360)

Zombies with traffic cones stuck to their heads, others getting sliced in two, being burned alive, or just smashed in the face with a soft toy. Not so much of a surprise considering your proprietary aim throughout the whole of Dead Rising 2 is to kill, mame, and disfigure as many of the living dead as humanly possible whilst trawling through the Las Vega inspired Fortune City. It's a highly enjoyable experience at times, but not without elements of repetition, and some issues which make this sequel feel slightly hacked together at the last minute. But at least it's for the most part, still quite addictive.

Dead Rising 2 sticks firmly to the blueprint established by the first game. The missions are largely similar, the whole idea of picking up almost anything and using it as a weapon is almost the same, as is the never-ending onslaught of zombies, and familiar time-based structure, all which form an altogether familiar, but rather fun game.

However, with this sequel (or what feels like a retry of sorts) developer Blue Castle Games has improved on many of the flaws of the original. The save system has been slightly overhauled, the game’s use of time no longer penalises you for failing missions, and the ability to combine weapons together provides ample reason alone for mindlessly running around and bashing as many zombies as you can. It’s still not without some issues though, and the whole idea of levelling up and going back through the game can get decided boring, often pretty repetitive at times.


Now that isn’t always such a bad thing per-say, with the game’s sandbox nature giving you plenty of the same things to do. It’s just a question of whether you want to keep doing them. And that can be a pretty big ask. Though for the first few hours or so, you will definitely want to stay in Chuck Greene’s world turned upside down.

Roaming around the glamorously hellish paradise that is Fortune City, beating down loads of living rotting corpses with almost anything you can pick up is what you'll be doing most of the time. And there's plenty of items available at your disposal to do this. Nearly everything can be used; saw blades, baseball bats, axes, tables, chairs, plant pots, soft toys, etc. You name it and you can probably use it to deliver death to the undead. It can be a rather wildly enjoyable affair.

Of course you could do this before. But now you have the ability to combine various weapons together into making a custom death-delivering machine, or just a push broom with shotgun on the end of it. Did someone say ‘boomstick’ anyone? All objects that are identified with a wrench icon can be combined with another item. Usually this still has to make some kind of logical sense; such as a water pistol combined with a gasoline canister becoming a flamethrower, and so on. The fact that you have such a huge range (nearly unlimited claims Capcom) of items at your disposal keeps this whole idea from going stale. But also another reason for backtracking your way all over Fortune City.

You’ll be doing a lot of that too whilst in the world of Dead Rising. This sequel, like with the original, has a hard time limit in which to complete the game, and is backed up by a shallow, but mildly compelling storyline.


After being framed for the recent zombie outbreak in Fortune City, our new hero Chuck Green (bye bye Frank West) has only 72 hours in which to clear his name, and find enough Zombrex (an expensive medicine) to keep his daughter from turning into a zombie before the military arrive. To make matters worse, the whole place is quarantined off as well.

After initially escaping to safety from new zombie infestation, you find yourself holed up in a safehouse in the centre of another shopping complex, and it’s from here where you’ll be stepping out into the world, killing lots and lots of things, whilst running rescue missions and helping stranded survivors.

The story establishes the time limit, and throughout the game every mission you do is also timed, taking a chunk out of the whole 72 hours you have. Multiple missions are radioed to you from the save house, and usually run concurrently with each other, meaning that you’ll often have to decide which ones you have time to do, and which ones to let go. Even if you don’t choose a particular mission they still expire, so juggling between them is reasonably important.


However, it is impossible to complete every mission, every side-quest, and to see and do everything the first time around. Instead, the game has been designed for multiple playthroughs, with some challenges requiring you to be significantly levelled up in order to complete them. Also, some missions can only be successfully taken on with good time management. On subsequent re-plays you should have a greater understanding of where things are, and which missions can be done at the same time before returning to the safe house.

In DR2 it is also possible to fail missions, even major ones, without much in the way of punishment. You can even let Katey die if you want to. The result is that the game’s eventual ending changes, and you are left with a few shallow, but mildly perplexing moral dilemmas. In any case it’s a far better system than the one in the first Dead Rising, in which failure could often lead back to the beginning of the game. Now, you can choose when you want to start up from day one again, fully powered up and ready to go.


Aiding with Dead Rising 2’s far more forgiving game design, comes a tweaked save system. In DR2 there a now a handful of bathrooms in which to save. And you can choose to use them, and thus save your game at any point in time, mid-mission or otherwise. Of course balancing out this increase in chances to savage your progress comes the cleaver design of positioning save points often at ends with where you have to go for your main missions. This means that you’ll have to make a choice to either: carry on until the next intended save point. Or: fight your way through more hordes of the undead to reach a bathroom.

Both choices are filled with similar dangers, and neither represents a truly easy option. Getting to a save point when having to stroll off the intended mission path also loses you valuable time, meaning that it’s more likely that you’ll have to play through the game again to make up for any missions you might have missed. But the idea, and implementation is sound. Still, the giving the player a firm choice makes for a fairer overall experience than in the original Dead Rising.


A fair amount of the game (read: most) simply sees you going from point A to point B, picking up stranded survivor and helping them back to the safe house, maybe follow up on a the next case objective in between, or at the same time, whilst killing, bludgeoning, and dealing as much punishment as possible to as many of the undead you can in the allotted time limit.

Along the way you will also encounter a few boss battles – usually either powered up super zombies, or crazed humans looking to stake their claim. But in what exactly, I’m not sure. They’re challenging to beat, to say the least. And you’ll often die initially, having comeback a little later on, levelled up and armed to the teeth in order to finally take them down.

Thankfully, as you should have spent at least a few hours roaming and killing plenty of what you see, accumulating more in the way of weaponry, and increasing your health and strength, then these encounters shouldn’t prevent you from progressing for too long. Instead they simply reaffirm the fact that the game wants to be played over and over again, and that you should have far more fun in completing it if you go about it this way.


Unfortunately, the game’s long loading times make constant backtracking and exploration a somewhat tiring experience. Fairly long loading screens occur when venturing into different areas of Fortune City, and in between cut-scenes, breaking up the action considerably. These are pretty lengthy and make each area feel disconnected from the last. In particular, it feels like you are simply going through a series of separate levels set in the same place while carrying over any weapons and items you happen to find along the way.

Although it is understandable why these occur from a technical perspective (especially when moving from area to area), one can’t help but wonder why Blue Castle Games could have used pre-recorded in-engine cinematics for the cut-scenes instead, thus reducing the amount of times the game needs to load. But as it stands, with all too frequent occurrences, they simply disrupt the flow of action and prevent you from really becoming immersed in the world that has been created.


At least its a world that you can share this time around.

For those of you who might somehow tire of the experience when going it alone, you’ll be pleased to find that the developers have also introduced a story mode co-op option for Dead Rising 2. This sees both players taking control as Chuck Greene, albeit in different outfits, battling hundreds of zombies, and performing all the same tasks as you would in the standard solo story. Although in cut-scenes only one version of Chuck is ever present - the host’s character always takes president.

The use of co-op works well for the most part, however is let down by some peculiar issues with the game’s save system in this mode. For example, when playing I found that only the host could actually save their story progress – the guest player only saves their level, which is extremely frustrating. Especially frustrating in fact, when you consider that your zombie kill counter is reset every time you choose to return. In addition when one player saves their progress, the other is unceremoniously booted from the game, thus having to rejoin with the host again.

A few annoying niggles aside, playing through the game in co-op is a great way for both players to level their characters up, whilst also exploring all Fortune City has to offer. In particular, picking up new items, customising weapons, and then trying them out on the nearest group of flesh eaters in lieu of completing the actual story is great fun, whilst also allowing you to learn the layout of the game and its many nuances before you do things proper on your own.


Taken as a variety of individual experiences, Dead Rising 2 can seem to be rather repetitive and rather mundane. However, combine the time spent mashing up zombies, whilst performing various escort missions, and investigating the shady goings on in Fortune City, it becomes strangely compelling.

The storyline even manages to deliver a few Romero-esque moments of political jousting, often criticising the sometimes selfish and voyeuristic nature of man. But at the same time it knows never to take itself too seriously. Protests against the mis-treatment of the undead is at odds with exactly what the game wants you to be doing – killing as many as possible. And definitely adds a comedic touch to the premise as it unfolds. That, along with the many colourful, and downright stereotypical characters you will meet along the way.


However, Dead Rising 2 isn’t for everyone. And while as many people are likely to be enthralled with the constant carnage on offer, equally as many will be turning away in boredom after only a few hours. What keeps things enjoyable though, is the unique mix of humour, likeable characters, and viscerally gory action.

The fun that comes with finding, and indeed making new combinations of weapons, before then trying them out on the nearest walking corpse is actually just as good as it sounds, while at the same time most of the complaints surrounding the first game have been completely resolved. And although a few cuts have also been made; you can no longer take photos of your bloodiest work whilst running around Fortune City. Plus the game’s frame rate regularly takes a dive, resulting in quite laggy controls. These problems aren’t enough to tarnish what is a mostly entertaining, though rather samey experience.

VERDICT: 8/10

Call Of Duty: Black Ops Gets The 3D Experience

So, along side Gran Turismo 5 and Killzone 3 another large AAA title gets 3D support. Yesterday, in a rather unexpected twist, Activision announced that Call Of Duty: Black Ops will come with 3D enabled upon release. If of course you have the right TV or monitor that can handle it.

"Development of stereoscopic 3D began as an R&D project, but once we saw what the technology brought to the Call of Duty experience, what a great fit and how immersive it was, we knew that we had to develop it for Black Ops," said Mark Lamia, Treyarch studio head.”

"We made sure the experience is seamless for gamers to use with a simple menu option to enable stereoscopic 3D or disable it at any time whether playing in the single player campaign, multiplayer or Zombies."

To play in 3D PC gamers will need a monitor that is capable of handling a 120Hz refresh rate, be that LCD or even an aging CRT – but one that is still up to the task, along with a pair of NVIDIA 3D Vision active-shutter glasses, and a NVIDIA GPU.

Naturally, console owners will need a HDTV branded ‘3D Ready’ if you happen to live in the UK, or a similarly compatible monitor if you happen to have one of those to spare.

There’s obviously no word on what resolution the game renders at in 3D at this point, although I’m willing to bet that it will be even more sub-HD than the 1024x600 framebuffer makeup of the standard 2D build if they choose to render two separate frames (one for each eye). Another scenario is that the developers have chosen to use a depth buffer, plus pixel shift approach, ala Crysis 2 to achieve the effect, needing only a fraction of GPU power that otherwise would be required.

However, the first hands-on report of the game running in 3D seems to hint at the former. Although we should find out for sure soon enough.

Eurogamer Expo: The Kinect Report

When reading various forum posts by avid gamers you get the impression that many people seem to want Kinect to fail, whilst many industry journalists tend to brush over the obvious issues with the device in the hope that the final experience will be on par with what they have been promised.

Complaints usually centre on the high levels of latency and inaccurate pointer tracking, both of which make the whole experience a rather flawed one. And while this is in fact very true, I can’t hep but feel that at least some have forgotten about the fun factor - the reason we actually gather round and play these things in the first place. Because whether or not Kinect actually works technologically as it should – which it doesn’t at the moment, at least not consistently – there’s no denying that the software can be incredibly enjoyable to play, especially for the casual crowd, in which latency is just another tech buzzword being thrown around in another write-up of the device.

That’s not to say Kinect’s lack of precision and pin-point accuracy doesn’t put a downer on things, because it clearly does. It does affect the gameplay, and it does reduce the feeling of immersion you get from almost being in the game.


Some experiences fare better than others. Kinect Sports for example, does in most of its games provide decent, and reasonably accurate full body tracking. Sure, there is noticeable latency, and the game does make allowances to compensate for the users actions in accordance with its own somewhat limited physics system. But it also delivers a more in-depth experience than anything the Wii has to offer in terms of similar software.

Compared to the PlayStation Move however, it feels like a backwards step. Sony’s motion control solution has completely proven itself with regards to featuring 1:1 accuracy with low latency precision. Kinect on the other hand, even now just over a month away from release, still has much to prove. And a load of promises, and conceptual gameplay ideas to deliver on.

The likes of Volleyball and Table Tennis in Kinect Sports actually shows some of that promise in the device. They’re both very fun to play, and feature pretty accurate tracking of your movements.


Table Tennis stood out more in this regard being comparative to its PlayStation Move counterpart in Sony’s Sports Champions. Latency was clearly higher of course, and like for like precision definitely seemed paired back in comparison. However, it wasn’t as far off as I originally expected. And using your entire body in combination with just your arm for movement and positioning seemed slightly more natural for me. Reaction time and accuracy was clearly reduced compared to the Move, and a lot of the time the tracking wasn’t as smooth or quite as precise as it could have been. Controlling the paddle in Table Tennis on the Move showed how much better the tracking was in Sony’s solution.


The same could be said about Beach Volleyball, in which your actions don’t always translate well into real-world physics in the game environment. The downside: It felt like the game was slightly on rails, slightly more in control than it should be. And the upside: It was both easy to get into and pretty enjoyable to play. Though, it remains to be seen how much depth each experience provides. However, this is something we won’t find out until the device actually comes into homes, away from controlled demonstrations, and limited playtests.


The worst game I played at the event for sure was Joyride. There’s very little to the experience as a whole. You play the game standing up, like with other Kinect titles, so there is no way in which to accelerate or to brake – the game does both for you. Instead all you do is steer your car around the track using both hands held out like you would when holding a steering wheel. Hardly inspiring, and overly simplistic. Occasionally you get the opportunity to boost, in which case you hold both arms close to your chest, and then thrust them forward in unison to activate it. You can also grab bonus items by reaching out to the sides whilst racing, and that’s about it.

Latency was noticeably higher than in Kinect sports, with there being a unmistakable amount of delay between your actions, and seeing them represented on screen. Whilst this may be understandable given the complexity of the full body tracking involved, and the processing required to pull it off, it was clearly apparent that most of the software just didn’t do it all that well. Joyride being one of the worst offenders.


Of course, Kinect isn’t aimed at the core gaming market. It’s currently aimed at the casual audience. And for them I think that it will work quite nicely. There’s no question that the amount of latency may be quite frustrating for some – think Motion Plus enabled Tiger Woods on the Wii and you have some idea of what I’m talking about - and that will definitely spill over into the people MS is aiming Kinect at. Though it certainly won’t be the be all and end all of the discussion.

Saying that the software on test at the EG Expo was clearly work in progress. Whilst I was surprised that Kinect was quick to scan in additional players, I was also disappointed to see how slow and inaccurate using your arm as a pointer was. It’s downright buggy at this point. In game things were noticeably better in all the titles I tried, though at this point in time, polish definitely needs to be made with regards to the smoothness in the overall body tracking, with less in the way of pre-scripted movements representing your actions on screen.

Disappointingly, nothing has really changed on the software side in nearly two years since the Kinect was first unveiled, since it turned from being a cool design idea into a workable reality.

The overall latency is still the same, and the errors in tracking are still unresolved. The only real difference is that Microsoft seems to have lost much of its initial imagination with regards to planned software for the device. This appears to have happened in conjunction with the reduction of tech powering Kinect. The lack of internal processing capabilities in the device, and a lowering in camera resolution does seemed to have limited what is really possible, to the point that many of the originally extensive, and rather creative experiences once planned are just no longer viable.

Saying that, software is still rampantly being worked on, having last minute touches added before release. Plus what we have here is just the first batch of titles taking a stab at using the technology. If it is indeed true what developers have recently said; that it’s squarely down to the software, more so than the actually hardware (though a little at odds with what we know about how the Kinect actually works), then things should change for the better with second and third generation games. I wouldn’t expect hardcore types experiences like Gears Of War and Halo however, as they would need a Nunchuck or Navigation Controller style add-on to work. But certainly something more fully featured than what we are seeing now.

Ultimately, the very nature of how Kinect works limits its potential compared to the PlayStation Move, which is not only considerably more accurate, but is obviously more versatile as well. Though it will no doubt over time find its footing with specific genre types, and different kinds of experiences outside the traditional ones expected, it has much to prove before it lives up to expectation. That is, if more developers actually get creative when working on new software for the device. Rather than dishing out the same old stuff the Wii crowd is beginning to tire of.


The one area in which Kinect currently does succeed is fun. However you feel about the latency, or mixed results of early body tracking, you can’t argue that although bizarre, and at times rather pointless, it still brings something mildly enjoyable to the table. Maybe Kinect isn’t the deepest motion control experience around, being initially quite shallow. But some of the games are in fact very fun to play, and will no doubt bring both friends and family together for some loose and decidedly non-serious gaming sessions.

I’m willing to bet that this will be one of the most popular things in gaming this Christmas. It’s different enough from the Wii in order to make it interesting, and not bad enough to be utterly forgettable. Despite not living up to it’s initial claims of truly ‘making you the controller’, and delivering on the promise of having new innovative experiences, it is far from the disaster many people on forums are making out it out to be.

Eurogamer Expo: Hands-On Gran Turismo 5

Killzone 3 in 3D didn’t quite impressive as much as it perhaps should have done. Let down by some very fuzzy graphics, upscaled and artefact filled, much of the subtleties so obviously noticeable when viewing things in the third dimension were lost. Whilst depth perception still remained, its usage somewhat limited by your reduced line of sight, with enemies being made a little harder to pick out from a distance.

Thankfully Gran Turismo 5 doesn’t suffer from any of these problems; instead you could comfortably describe it as being Sony’s real flagship demonstration for the benefits of 3D gaming.


My first taste of GT5 came standing next to a player seated down next to me, right in the middle of a race. Putting on a second set of LCD shutter glasses provided for spectators to become acquainted with the 3D effect, I was initially a little disappointed. At an angle the 3D effect in GT5 looked rather strange. The car appeared to hover above the track whilst the scenery seemingly moved around it. However, when finally sitting down to go hands-on, positioned directly in front of the screen, things changed completely.

The 3D effect in GT5 is nothing short of superb. The vast levels of depth perception, and visual judgement of distance really come close to replicating the actual experiencre of being right there, hovering behind the car in the classic outside view, as I pelted around both the Tokyo and Rome circuits.

Not only can you accurately gauge distances between cars and the surrounding environment, you can also read with unparalleled precision the angle in which your car is situated in relation to others on the track in a real-world 3D space. Subtleties that previously had to be second-guessed from a 2D perspective in a 3D game are now opened right up allowing you to react and respond almost as you would in reality. I say almost, as the 3D version of the game was only controllable with a DS3 at the event. The 2D build was kitted out with a high-end Logitech GT Force wheel.

Also compared to seeing KZ3 in 3D, there is very little in the way of double image ghosting in GT5. The main reason for this is that Polyphony Digital’s driving sim runs mostly at a smooth 60 frame per-second, thus eliminating this unwanted effect. Some crosstalk was still present however. Although this is down to the nature of the LCD display it self not being able to provide a completely smear-free image, rather than the actual game, so it’s not really an issue.


Visually GT5 looked suitably stunning, in both 2D and 3D modes. The high levels of image quality gave way to a crisp and clean final image, both clinical in nature whilst appearing natural at the same time. Sharp, detailed textures are complemented with incredibly detailed car models, and lavish roadside scenery. A combination of real-time lighting, HDR, and pre-baked solutions also gave the game a bespoke sense of depth, whilst the overall quality of the rendering provides a photo realistic feel to the proceedings.

In terms of gameplay GT5 looks to have been given another massive change to its handling system. Compared to the Time Trial demo, the overall handling system feels far weightier, with under steer being as much of an issue as over steer. Not that this is a fault however, as you now have an even greater awareness of each vehicles weight and grip characteristics than before. In particular, racing at too high a speed can often lead to an excess of unwanted grip being produced, in which case careful braking and proper timing is required in order to quickly, but deliberately manuvere your way around sharp turns and constant changes around the track.

One thing I noticed is that it is actually a lot easier to not spin out of control this time around. More often than not going too fast leads you straight into a wall, or careering off the intended path, rather than having you car slide around in circles right in the middle of the road. Although that does happen when you try too hard to over compensate.


The balance is now even more determined by small incremental changes in weight, speed and grip than before, with much in the way to learn compared to GT5 Prologue – which now feels a little archaic in comparison. That said, I didn’t tinker too much with the few gameplay-based options that you have before each single race. And I believe that a variety of handling types may be available in what looked like an Arcade mode of sorts. I simply kept the ‘standard’ setting as that seemed like the most obvious choice in best representing the feel the developers had intended for the game.

Sadly I didn’t get a chance to sample all of the cars and tracks featured in the demo, and couldn’t compare how well the handling mechanics felt when using the GT Force wheel to the standard DS3 pad. However my short time with demo was more than enough to convince me that the game has gone through some serious upgrades over the last year or two alone, and that the 3D effect was one of the most promising I have ever seen.


Out of Sony’s line-up GT5 stood out by far as the most polished of all the first party games on display. It may not have delivered the high-level intensity of Killzone 3, or the same innovative talents as Little Big Planet 2, but it did provide a largely successful showcase for the 3D format, along with being one of the most accomplished driving games to be seen so far.

Update: looks like I should have switched to the 'professional' option for a more realistic, and less grounded approach to the games handling - the sources for the lack of oversteer almost certainly originates from this point. Although even the 'normal' option is considerably better than before. Going down the professional route will definitely be something I'll be doing in the final game. Shame I missed out on it at the Expo.

Eurogamer Expo: Hands-On Killzone 3

Killzone 3 was one of the most anticipated titles that I wanted to see at the EG Expo. It would not only be my first chance to gain some much-needed hands-on time with the title, but also get the full experience in 3D. Seeing as the game has been singled out time and time again as the reason not only to own a 3D TV, but also to feature the distinct tangible benefits of this latest picture format more so than any other title, I was intrigued to see on whether it could really live up to those promises.


Guerrilla Games latest begins with you on board the series trademark Intruder attack vessel, an open-top substitute for the traditional futuristic chopper. Equipped with a mini-gun at this point, the game takes you through a brief on-rails ride shooting down the various enemy energy rigs situated directly below you. Filled with pyrotechnics and tons of particle effects, the carefully orchestrated set pieces of destruction are immense. More, so in 3D in which various particles, such as snow, smoke and debris all coming flying out of the screen.

Moments later you are shot down, and then strung out across the cold icy ground, left for dead by the enemy. At this point the game ditches the mini-gun, and sees you taking on the Helghast forces on foot, standard guns in tow as you venture further into their territory for a spot of good old-fashioned tactical shooting. It’s here where Killzone 3 really comes into its own.

Initially not much appears to have changed; the same level of intensity found in Killzone 2 remains fully intact, and as brutally realistic as ever. Gunfights see the enemy troopers constantly going in and out of cover, flanking, moving between spots, and intelligently retreating when being pinned down by your fire. However, it is now even easier to go into cover than before. The system is more responsive, allowing you to use it quickly and decisively when needed. At the same time you can still go in all guns blazing. The environment is more open, and appears to allow a levelheaded mix of cover-point shooting, and head-to-head run and gun bloodbaths.


One of the things that I also noticed was that the game’s controls felt smoother and slightly more responsive this time around. In KZ2 there was a noticeably higher delay between performing a button press or stick movement on the controller before it actually registered on screen. Originally this added weight to the feel of the weapons, although it also made for a very slightly laggy experience at times - more noticeable than Halo 3’s 100ms of latency. For Killzone 3 this has been subtly improved. You can feel the distinct change on offer here instantly, while the weight of aiming and holding the game’s various weapons has not diminished. Instead it feels very responsive now.

Smacking someone in the face instead of shooting them in the head has also seen changes. Now the melee system looks to be context sensitive, with you performing different moves depending entirely on situation. No longer are you just pistol-whipping the Helghast into submission. Stabbing then with the knife is a common option, as is a brutally visceral stealth kill when creeping up from behind. I barely needed to do any of this though, with plenty of ammo and weapons around from fallen Helghast troopers, it was definitely more a case wanting to do it for pure satisfaction purposes.

KZ3 also features what looks like being the current HDR lighting of the time, but for gameplay. It has jetpacks. These are activated using the L1 button, and feel far more realistic than those found in Halo 3. Altitude is strictly controlled, as is flight time, so it definitely looks to be more of a realistic integration with the rest of the series grounded nature. Personally, I found the use of jetpacks slightly clumsy in KZ3, although only tried them out very briefly given the limited time I had with the demo.


Visually, there is no doubt that KZ3 looks to be a massive jump over the second game, despite the fact that the image quality of the 3D rendering mode leaves a lot to be desired. There’s far more in the way of particle effects filling up the screen; subtle snow effects are kicked up by both the enemies, and your soldiers feet, as well as being found flying through the air. Smoke and fire particles return with their volumetric look really adding to the sense of intensity when being on the battlefield, and the games lighting system seems to have had a nice expansion of the HDR styled bloom effect from the first game. Lots of nice real-time shadows, and small glimpses of SSAO are present.

All demo units of the game were fitted out with the latest Sony 3D ready HDTV’s, complete with LCD shutter glasses. And of course the game was fully playable in 3D. However, the experience in Killzone 3 was both a shining example of what was possible with the format, and a bitter disappointment given the game’s graphical quality in this mode. Props should be given to Guerrilla for not cutting back of any geometric detail, or pairing back the amount of stuff being displayed on screen at once. It’s incredible to think that in 3D that Killzone 3 is rendering everything twice with no reduction in art assets being used, which is no mean feat I can assure you.


2D


3D

Sadly the use of 3D in KZ3 is no work of a miracle. Instead massive cuts have been made to the game’s framebuffer resolution. Rendering in a mere 640x716 with MLAA, the game is extremely rough around the edges. Harsh jagged lines and bouts of pixelation littered the screen, as did the additional softness caused by some heavy upscaling. In fact at various points the game looked to suffer from as many artefacts as Wii games do when being upscaled. Not so great to be fair, and all these blemishes completely ruin the added depth perception and sense of immersion that the actual 3D effect provides.

The lower resolution effects in the standard 720p 2D mode also looked noticeably worse, suffering from all the same issues as the rest of the game. Now halved down to 320x360, smoke and particles appear heavily artefacted and really messy, distracting from the rest of the scene although still aiding in keeping you immersed in the experience.

That said the 3D mode in Killzone 3 still gives the feeling of bringing the player closer to the action. No matter how rough and poor looking most of the game appears in 3D, distance and depth are far easier to judge. And the impact of this can clearly be felt during play. It is easier to both accurately throw a grenade, and more natural to perform a close quarters melee attack knowing that they are pretty likely to hit as you expect them to. The use of 3D doesn’t improve poor judgement, but it does make things easier, when of course you can properly see what’s going on.


The build I played was the same Pre-Alpha code that featured at this year’s E3 - the very same one that I performed a tech analysis of some screens on earlier in June. Most of what I said back then still stands today. Other than perhaps when I mentioned that upscaling might well be less noticeable in 3D given the various reactions sighted by the gaming press in general. While this may be true for some, for me it was mostly the exact opposite, with the 3D separation limiting the rawness of the upscaling, but certainly amplifying its softness and the overall lack of image quality caused by it.

Of course there is still some six months to go before the game gets released, leaving plenty of time for last-minute optimisations, and a small but still slightly beneficial increase in overall framebuffer resolution. There’s also the exceptionally stunning looking 2D build, in which none of these aforementioned issues apply, and all the gameplay enhancements remain. So, either way you’re going to have a choice in the matter.


Overall, Killzone 3 is looking like a superb follow up to arguably one of the most technically accomplished titles this generation. The basic game plays even better than before, with larger set pieces and more responsive controls. And despite the extremely poor image quality, the use of 3D has obvious benefits amongst the heavy downsides required for its inclusion. Sure enough, in it’s currently messy state 3D isn’t going to blow you away visually, but it does take a vital stepping stone into showing what’s in store for the future.
