    One of the best Splinter Cell games in the franchise. The graphics are unbelievable, the voice acting is quite good and humorous, and the gameplay is flawless. Overall, due to the game being on Steam without having to worry about a scratched a corrupt disc, makes this game the best of all.

    First, straight off the bat, I'd like to say, GREATEST Splinter Cell game in the entire series. I mean, bravo, 2 thumbs up. Gameplay is very organized and not too tweaked around like the later games. Story line was exceptional. Running on a very good computer, this game rarely has any glitches or bugs, so, good job Ubisoft. The co-op portion is possibly the best part about Chaos Theory.First, straight off the bat, I'd like to say, GREATEST Splinter Cell game in the entire series. I mean, bravo, 2 thumbs up.

If you love taking out bad guys in stealth over lan or online, this is probably the best game to do it in. Very, very fun game. I prefer it highly over Double Agent in my opinion. 10/10 Expand

    Everyone, Please ignore this "Ryan J." He apparently has a bad taste for good games (no offense "Ryan"), but then again I suppose you cant make everyone happy these days. Anyways, on to my review. :)

    The gameplay is pretty good, though it seems to start slow in the beginning. The levels were taken good care of in the design/layout department. The graphics are really good, though

    Hey whoever is writing the reviews as Ryan J. and Nate B.: you are entitled to voice your opinion, but only once, so enough of the double posting. [Ed: 2nd post deleted....] This game is phenomenal. I can see why the attention deficit crowd would call this boring, since this game requires patience and skill. Well worth your money.

    I own this game for both pc and xbox. The multilayer concept and style of gameplay will keep this game among my few favorites. Sadly conviction was overseen by a baboon and the series has ended with a big fat epic fail. There will never be another game like this.

    Easily the best installment of the Splinter Cell series, the game play is stealthy, tactical, and just plain satisfying.

    I missed the boat when this game first came out, but i recently picked it up for the PC and i was absolutely stunned by how great it looked. Game play is solid when the AI isnt being brainless or clairvoyant. Story is what you'd expect from Clancy. Other than that highly recommended!

    Great Game, great story and great graphics. This game together with Hitman is one of the BEST single player games of its Era. Much like Half life, it changed alot of things on the Market, a Modern Tomb Raider if you will. +10!

    Best splinter cell by far. Along Metal gear solid, best stealth game ever.
    It was so ahead of it's time... released in 2005 and it has insane textures details and lightning/shadows. If it wasn't for the character models you would say this was released on ps3 gen.

    The best of the series so far. All three parts (Single Player, Cooperative, Spies vs Mercenaries) could have been their own game - they are all that good. This is a MUST HAVE game.

    This game is the best game I have ever played. I know it's sounds cliched but it's true, although I don't have a good enoug internet connection for the multiplayer :( the single player is enough to keep a player going. I give it 1000/10

    Sure there is some bugs in it, what software doesn't have bugs? It is a great game though, one definitely worth buying, the most important part of course is great gameplay single and multi player, a shame about a biggish patch though.

    Having only played the single player i can only comment on that. Basically if you liked the first SC formula then this game is for you. Not a great deal is different but everything is better. Better graphics, sound, dialogue and less linearity in missions. Bigger mission maps also. If it aint broke dont fix it. Yes occasioanl bug appears but nothing critical.

    AWESOME single player, one of the best single player games ever. Versus, while updated SLIGHTLY in technical aspects, is actually a bit lacking in gameplay compared to Pandora Tomorrow. Alot of the new additions end up taking away from the fun, and the maps just don't do it for me. Coop just plain doesn't work.

    Gameplay was solid and AI was nice but somewhat predictable. I must say though the multiplayer is AMAZING, though sadly it is only limited to 4 players max. But the fact that you can pit 2 spies (3rd person) against 2 mercenaries (1st person) yet have it balance out very evenly is facinating and fun :D Hope Conviction brings the same multiplayer.

    WoW ! For a game that came out in 2005, it beats the hell out of some new ones in 2009. The graphics are awesome, same with the animation. The environment is awesome ! You can shoot out any light you please, making the stealth factor go way up. The ability to use your knife to cut a hole in a tent and enter through it so you can sneak up on someone is amazing.

The downside of the game is quite simply the music which was nothing special and the story while being epic had a very un-epic ending. Overall a really good quality lengthy game.8.8/10. Expand

    SC Chaos Theory is Great in almost every way! The Graphics/effects are good enough for me, and performance is perfect on a E6600 + 9600GT. I really can't think of any big problems with this one, just that sometimes the Enemy AI can get a little glitchy and the enemies taunts(talking) can get sort of annoying and kinda' foolish... also an enemy's head's turning-angle can turn around tooSC Chaos Theory is Great in almost every way!

    Writing in video games is a subject that doesn't get a lot of attention, but Chaos Theory features a simply great script. Not only is it complex and deep, it's also surprisingly funny. [Apr 2005, p.112]

    When combined with the excellent animations, the game feels incredibly cinematic, and on a high-end graphics card the game is stunning. Each level is a grand set piece in which players stylishly accomplish their goals.
  3. A serious improvement in any way you care to name, from gameplay to its newly, eerily realistic graphics.
