Finally, "Versus" mode. It's the reason I shelled out $50. I played a couple hours of this, and also went through all the tutorials and the overviews of the new maps. Damn, it's better than ever. The core of the gameplay is still the same- Spies and Mercs, two on two. Mercs get all the firepower and spies get all the tech toys. Mercs play in first-person view and spies have the magical ability to watch their own backs. It's a great formula, and Ubisoft has made modifications that make the game fairer, more complex, and flat out more entertaining.
Here's a few of the better changes- Mercs are deadlier. Yeah, in principle they were already the killing squad and smart spies avoided head-on confrontation... But in reality the spies in PT could be every bit as deadly as the Mercs. Part of this was the HUGE advantage of being able to see your surroundings better, and having better vision modes. Also, mercs were too easy to stun, and once stunned the spy could take his time breaking his opponent's neck.
Those happy spying days are long past. Mercs have a couple of devastating close combat moves now, most impressive of which is a "spin" attack that will throw the spy to the ground, regardless of which side of you he's standing or crouching. It makes you a little dizzy, so "spinning" constantly is no strategy, but it does help even the odds at close range. Also, the merc has a couple extra guns to choose from. The fully automatic machine gun is very powerful at medium range, but even better is the shotgun- it will take down a spy in one shot at close range. So spin, and while they're on the ground one shot with the shotgun. Dead spy.
There's a bunch of new gadgets, some more useful than others... Mercs get a new kind of mine (a poison mine, which rapidly saps away the life of a spy but has no effect on mercs). They also get a 'Camera Net uplink', which is pretty nifty. Every map (including the older maps from Pandora Tomorrow) are outfitted with a handful of special indestructable cameras in strategic positions, and mercenaries can 'link' up to those cameras and look around at any time. They can turn them and zoom in and out and get a pretty good view of the main thoroughfares of each zone, and there's really nothing a spy can do to avoid it... other than knowing where the cameras are and keeping far out of their way.
On the other side, spies get an active camouflage, similar to the invisibility devices from Metal Gear Solid or Ghost in the Shell (how's that for realistic?) It's kinda crappy, though... it has only a short battery life, and it doesn't fool motion detectors, and if you move too fast you become visible. Better is the added functionality of the "Sticky Cam". In PT, you could toss a sticky cam on a wall and look around, and even set off a little booby trap... but once you needed to do something else, and you cancelled out of the camera mode, you lost that camera forever. It was pretty impractical. NOW spies can look back at their last sticky cam at any time... meaning you could be on the other side of the map looking at a critical spot, guiding your partner along. That's cool.
Other cool things include even better use of the Live Communicator and headset- Now, as a spy, you can shout into the headset and mercs will hear you. That's handy for creating distractions, and its fun taunting em. Too bad they hunt you down and kill you for it... mercs have no sense of humor. The heads-up displays for both sides are a little smarter... It's easier to see objectives, and the mercs have a much better reticule-sound sensor thingy. Other nice touches include a low hum when the mercs use their lasers, and that results in less sound sensitivity. And the new maps have opportunities for spies to use their snazzy dual moves from the co-op game (and mercs now have an opportunity to get easy double kills with one grenade).
About the maps- There are several popular maps brought over, almost unchanged, from Pandora Tomorrow. I played several rounds on the fantastic Riverside Mall stage and the ONLY changes I detected was the introduction of the armored cameras for the merc's Camera Net ability, and the floor in the Hi Fi area now creaks. That's it. I haven't tried the other maps (including the Bank, Warehouse, Museum, and Deftech Belew). I assume the changes to those maps have been minimal as well.
But the new maps... well, they're fantastic. You won't be spending much time in Riverside Mall after you get a chance to play in the Aquarius, the Club, or the Factory. They're all BIG... I think the biggest map from the first game was probably Deftech, and all these maps feel bigger. EAch map has its own personality, with one (Factory) feeling very much like Deftech, another (Aquarius) plays somewhat like the Museum, and so on. They all have unique touches that, in my opinion, inject a lot of life into the game.
Take Aquarius as one example. The spies must meet three out of five possible objectives on the map. Unlike Pandora Tomorrow several different kinds of objectives may be contained on one map at the same time. For instance, one objective in Aquarius is a retrieval mission- you must take a "hard drive" from one location to a safe spot elsewhere. There are also "neutralize" objectives (similar to the standard Pandora Tomorrow stand-at-the-objective-for-twelve-seconds missions). Finally, there are bombing objectives, in which you place a bomb and the mercs have about 25 seconds (that can be a loooong time) to destroy your bomb.
On top of having multiple objectives, completing any single objective has some effect on the map that makes life easier for the spies. The "retrieval" objective, for instance, is difficult to do... but if you accomplish it, all the laser traps on the stage are deactivated, and those are more or less the only traps on the map. Complete one of the neutralize missions and most of the lights go out. Successfully place a bomb and several rooms fill up with thick steam... which the spies can see through with their heat vision, but mercs are left virtually blind.
So the balance shifts as the game goes on- mercs start out with a well-defended fortress and the spies must gradually steal away their advantage. It's a hell of a lot of fun, and the strategy is quite a bit more complicated (and therefore less predictable) than the PT experience. And that's just ONE of the new maps. Some other maps have entirely different mechanics. One in particular, the Orphanage, is so radical that it will either be a titanic battle of skill or a spy-shooting gallery.
All in all I lost track of a couple hours playing Chaos Theory "Versus" mode. It's better than ever, in my opinion the best Live experience possible, as long as you can reliably find three people who can enjoy the give-and-take nature of the game. I can't wait to play a few rounds with other Chewers.
