Xbox Critic Reviews

Three brilliant games rolled into one that could all easily be sold separately. The single player is incredibly satisfying, co-op is one of a kind and adds a fresh and very compelling face to the underused online co-op genre and the adversarial mode is simply brilliant once again; an online experience no person with high speed internet should miss.

By far the best game that the series has produced.

Ultimately, Chaos Theory leaves the player stunned, excited and thoroughly satisfied. A landmark achievement in stealth gaming. [Xbox World]

I can't say enough about the graphics. I never knew there were so many shades of black. Even though much of the game is played in the shadows there is no shortage of detail.

Ubisoft's obvious dedication and purity of vision shines through in every single minute that you're playing. It never seems to get old, it's rarely frustrating, and delivers its payload of stealth, action, strategy and exploration right on target. If there's a more complete gaming experience on Xbox, I've yet to see it.

Ubi has improved virtually every aspect of the gameplay from the previous two versions, and introduced even more new options and gameplay types. With the solo campaign, co-op campaign and online multiplayer, it's almost like having three games in one.

No longer is there just one way to solve a treacherous night mission before the enemy picks up your audio signature: stealth will pay off just as well as good old-fashioned ultraviolence.

And the co-op means that, like the previous two games, Chaos Theory is as close to an essential buy as we can imagine.

Although everything in the game has been improved, nothing makes a bigger difference than the new co-op mode, which can be played via splitscreen, system link, and Xbox Live. That's right, you and a buddy can now join up to take down enemies and pull off a variety of acrobatic moves, and it may very well be the most satisfying experience I've ever had on Live.

Visually spectacular and hugely rewarding.
