The a.i isn't as dumb in comparison to splinter cell blacklist and other future installments.
This game excells in the freedom you are given in moving around the map, and exploring. The game feels large and big, unlike splinter cell blacklist where their idea of "immersive maps" were tiny little vents, and occasional pipes,and ledges that all led to the same place. The game even lets pick what objective you want to get done first. As said before the A.I is not incompetent, and will actually respond to the situation like believable humans, unlike future installments where they all of sudden know there's a guy in the premissis when you've never been spotted or killed any one. The mechanics are defined and detailed, you can split jump, freely traverse the map with parkour, crouch roll, sc 3000 machanics work exceptionally, and more features that LATER games removed... Unlike future installments this game focuses on stealth making it well detailed, unlike blacklist where the combat gameplay was boring and the stealth gameplay was subpar and less detailed. The only set backs in this game are that the game sometimes feels repetitive and the story is forgettable.

Lambert: Sam we need you to save the world
Sam: K

Beyond that the game has no multiplayer anymore, and the game wiped my save data. This was most likely the work of ubisoft and their greedy snake like business practices. However the multiplayer can still be accessed through tungle and other things that I didn't bother myself with. I suggest you give it a try if you're look for a more defined stealth experience.

A childhood favourite of mine that I maintain is still one of the best stealth games ever made. This and the first game are classics that I will always cherish and I believe many others will do as well. It's a shame that Pandora Tomorrow is not available on Steam, nor the old gen version of Double Agent, as they were also very good games. Double Agent (new gen) was still a good game but it was on the other side of the peak of the bell curve, and the series unfortunately plummetted thereafter. I would stick to the original 3 (and Double Agent is still quite tolerable), this one being the best. Go forth and stack bodies on top of one another in the corner of a dark room for your own amusement.
By the way the soundtrack for this game as well as Double Agent are incredible so give those a listen as well!!!!!!!!!!!!!!11111111111111122222222222333333334444445

Sam Fisher: Bad news.
Guard: I knew there were ninjas around here!
Sam Fisher: What?
Guard: Yeah, you've gotta be a ninja. How else could you sneak up and grab me like that?
Sam Fisher: Listen, I don't know what...
Guard: Wow! A real, live, ninja! I can't believe it!
Sam Fisher: Listen, I'm going to kill you if...
Guard: Wow Killed by a ninja... cool!

LOVE THIS GAME, old times.

First off, this is my favorite game of all time. I've had it for a long time in physical format, but due to it's drm it's unplayable on modern systems, so I bought the steam version. I was a bit afraid of how it would run based on some of the reviews that have reported problems, so I was ready to issue a steam refund just in case.

So here's the score: this game is flawless. I've seen some negative reviews and let me address some of them. First of all, all those who say it's unplayable with keyboard and mouse are idiots, no two ways about it. You control your speed via the mouse wheel. It's that simple. Besides, you can customize the controls to your heart's content. Second off, no, it doesn't have checkpoints. And you know why? Because it doesn't need them! It has a quicksave function! I swear, some people...

How about the game itself? It's the best stealth game of all time. Period. You have full feedback of how much noise you make and how much noise is in the environment, how visible you are, you get a lot of tools for dispatching or distracting your enemies, you have nightvision, thermal vision and even "electric" vision that let's you see objects that use electricity (useful when completing some of the objectives). It has a fairly intelligent AI. The game is a bit too easy if you just kill everyone in my opinion but it's damn fun. If you like the suspense of stealth, look no further.

The graphics still hold up to this day in my opinion. Some of the round objects are a bit angular, but it doesn't take me out of the experience, and the textures still look great. There's also a surprising ammount of color that, compared to a lot of modern games, are a breath of fresh air. The sound design is superb and the soundtrack just ups the suspense. The music is low key and dynamic, changing to the gameplay.

Some of the writing is a bit too convoluted for me. Don't get me wrong, it's good, but it's hard to follow, especially for the first time playing. You really have to invest your brain into the story or you'll get lost in it.

All in all, if you even remotely like stealth games don't you dare miss out on this one.

Great game, often considered the highlight of the Splinter Cell series. Chaos Theory has 3 complete modes in single-player, co-op, and versus, at the time of its release very unique. In particular, the Spies vs. Mercs multi-player was an insanely fun and revolutionary experience, that for some strange reason Ubisoft has never replicated in later titles. Unfortunately, the co-op and versus modes are dead online, so the only real content purchasing it now is in single-player.

If you buy the game now, you're buying it only for the single-player experience. Still worthwhile in my opinion, but if you're looking for some multiplayer action, you're better off looking at the newest title (Blacklist at the time of writing).

Let me specify something- for 8 years, this has been my favorite game of all time. I played the absolute ♥♥♥♥ out of the xbox version of it- and while it may feel more suited to a controller, it can be handled just as well on a mouse and keyboard (though you may want to bind the keys to your liking). Since there's less of them- we'll start with the bad things, shall we?

Stealth games NEED good, balanced cpu opponents. While the game gets the awareness of guards correct on a standard basis- the dudes you're sneaking past can be remarkably stupid, and occasionally even the converse of that, as it has its faults sometimes with twitchy/schizophrenic AI.

The character models' faces can be REALLY ugly. Mainly, that comes from stretching in an exaggerated expression, as grabbing someone and holding a knife to their neck raises their eyebrows roughly 3 feet above their face, and their mouths even wider than the area aforementioned. Their eyelids are also triangles.

Another fault for the PC version is that it doesn't quite have the sound design that the xbox version did- sound effects don't fade and echo like they should. Which is kind of bizarre! It's not often that the console counterpart ends up sounding better than PC master race's version.

There are a few issues in the multiplayer modes:

-Game can desync and completely ♥♥♥♥ up a mission that you and your partner had spent an hour on
-This game absolutely hates when you Alt+Tab and will kick you off the server for doing it too much

-Opens separate program
-Completely different (and less visually appealing) engine
-Resolutions only offered in 4:3 format (but can be easily fixed by editing default.ini)
-Some of the maps are so huge it boggles your ♥♥♥♥ing mind that ubi thought only 4 players could support it

Now then- I've told you what isn't so hot about the game, and if all of that turns you off, that's okay.

So what makes Chaos Theory so great?

Make no mistake, gameplay is the breading AND the frosting on this delicious cake. The engine is completely revamped from its' predecessors, which is a magical thing that they were able to tear down what they had before that was already superb, and make something that is nearly perfect. There's a new sound meter, that lets you take a look at just how noisy you are in a situation, which makes for a better sense of immersion- rather than LOUD/NOT LOUD. The new engine the game runs on feels substantially smoother than SC or Pandora Tomorrow (which is still yet to see a steam release); All of your actions, as well as the AI's, both look and feel realistic. There's no half-hearted spring step like the original, nor do guards have to hug walls to get past eachother. All you have to worry about is coming up with the method to either stun your foe, eliminate him, or how to slip past him unnoticed. I often prefer the latter, but when in co-op, you can't really trust your partner, nor yourself to be this stealthy. You're better off quick-saving frequently or just knocking out whomever you encounter (or both!).

Sound-wise, the game sounds awesome. Stellar voice acting, great sound effects, and some of the greatest music in a game ever. In fact, Ubisoft was so pleased by composer Amon Tobin's work, they released the soundtrack a MONTH before the game was due. Tobin was able to create the tense atmosphere of the game, all while retaining the feel that you're a ghost's shadow. You ARE what goes bump in the night. Needless to say, the game's OST has wound up on every different generation of an MP3 player I've had.

Seriously. Just listen to it.

The voices in the game sound smooth and believable at every time. There's no forced lines like there were in Pandora Tomorrow, where there was that occasional young voice in the ambient audio tracks that absolutely did not fit the bill for the lines or the character he was given.


That line is going to haunt me til the day I die.

Like I've explained before, the game still looks nice, visually. The environments look polished, with the lights shining in just the right spots that make the game still a pleasure to look at, nearly a decade after release. The character models are very nicely detailed in terms of both texture, and shape. With bumps and edges on not just their faces, but clothing as well. In a game about stealth, you could imagine how important shadows and lighting are- and the balancing of the light-index along with the visuals work great (although this excludes a few particular downloadable co-op levels). The Co-op looks just like the Singleplayer, and doesn't sacrifice the engine for the sake of performance. But the extra levels included in the v1.05 patch leave a LOT to be desired. It feels like there was a completely different designer who had absolutely no spatial awareness, and didn't even understand how lighting works- and that large, stretched blood textures serve no purpose when there is no body they are connected to. Stay away from those maps if you wish not for your partner and yourself to succumb to occular leprosy.

How do I love thee, Versus? Let me count the ways.
1. When I grabbed parker and threw him off a ledge, breaking his neck.
2. Charging into and scaring the ♥♥♥♥ out of Binary_2 right after the elevator doors opened on 'Club House'.
3. Both Parker and I getting killed after bd648 fired a grenade into the rafters, taking the ceiling along with it.
4. wwchicken running headlong into yet another proximity mine next to the VIDEO GAMES terminal in 'River Mall'.

Versus makes its' return from Pandora Tomorrow, and with a vengeance. Gameplay is considerably more balanced, providing an easier challenge for the mercs. Mercs can now hit spies in the FACE, and knock them down- which levels the playing field, since spies have a tendency to sneak up and break your neck. You can also customize your loadouts for both classes, which is nice when you're trying to balance the game to fit your playstyle. Spies are still stuck with their shocker rifle, but mercs have the option to take either their default assault rifle, an SMG, or a shotgun. There's various things you can use on both sides as well, including spy traps, tracking bullets, and even stealth camouflage. It's all there, and it's a blast to play. I have no idea why there's so few people playing such a fantastic game. I mean, Counterstrike came out 13 years ago, and it's still one of the most played games on Steam.

Where is the JUSTICE.

TL;DR This game is fun as hell. If you haven't played it, and you love to be a stealthy SOB, get your hands on this delicious classic. Don't care about the multiplayer/ have no friends? The singleplayer tells a great story that can be beaten anywhere from 10-20 hours. A great deal that you can get on steam for an average 5-10 bucks. Wouldn't miss it for the world.

The peak of the Splinter Cell series, one of my favourite games of all time.
Then Fisher got locked up and sold his daughter for meth and regretted this poor decision.

Grim: The Maria Narcissa.
Fisher: Sounds like you are setting me up for another blind date.
Grim: The Maria Narcissa is a boat.
Fisher: So was the last girl you set me up with...
Grim: Fisher!
Fisher: Sorry.

Bank Guard #1: Hey, Emilio, have you seen those new motion sensing lights?
Bank Guard #2: No! What do they do?
Bank Guard #1: When they detect movement, the light turns on!
Bank Guard #2: That's... that's amazing!
Bank Guard #1: Like magic!

Fisher: Lambert, now that I got 50 million dollars with me, it's time to talk about a raise.
Lambert: Hmmm... 25 cents an hour and not a penny more.
Fisher: Deal!

And these are just conversations, I haven't even started about the intriguing gameplay yet...

I bought this game quite skeptical about all the praise it got, i went in with extremely high expectations and it didnt disappoint! Definitely worth the 10 dollars for all the replay value and fun factor of the game! Although one mission ramps up the difficulty to almost impossible levels but is beatable, and because of that i rate this 9/10

I have just finished the 3rd mission in this game. I played TCSC Blacklist earlier this year and enjoyed that game, so based on the reviews I bought this one. I have to say that I am enjoying this 2005 game even more than the 2013 one! I guess that its because I like stealth games and Chaos Theory is certainly a stealth game done well. My only criticism is that it is mostly, but not completely linear, since there is clearly an 'ideal' path to take to complete each mission and in some places only one possible path. But importantly the game does not rush the player - a key factor of stealth games. I remain amazed that a game which is over 10 years old can give me so much enjoyment.
