(After fiddling with the poor controls) Chaos Theory still holds up 11-ish years after release. Though I consider Conviction and Blacklist to be rock solid games, Chaos Theory is purebred stealth. The sound design/soundtrack is excellent, the graphics were incredible for the time (and are fine to look at today), and the dialogue between Fisher and his handlers is witty and entertaining. This is my favorite Splinter Cell and an all around must play for stealth fans. I personally have a hard time going back to older games and even though I played Conviction and Blacklist before this one, I can still find it amazing. If that doesn't speak for the quality, I don't know what else will.

It's very cheap now and can be picked up for dirt cheap in sales. As far as my experience has gone, it has no issues on modern rigs. The biggest downside is that it ran on Gamespy, so the multiplayer and co-op functionality is gone.

Ive played this since its release on Xbox 1, the first one. This is a great gameplay, well above todays standard, and infinite above Ubisoft´s current standard.

The Story is well enough to fill its purpose

Played this game on the original Xbox years ago. Its even better on PC in my opinion.
AI is good but repetitive so there is not much replay value aside few specific points in certain missions.
The graphics are great for such a older game and of course the voice acting is awesome.

Best stealth game I've ever played after hitman 2. 10/10
You can basicly play this game 2 ways stealthy (like a real agent) or assault(not on all missions but it can be very fun and challenging).
Another big plus in this game is the humor which made me laugh out loud many times.
The only negative thing is that Ubisoft doesn't support the official multiplayer servers any more,I use to play that for many hour on my disc copy of this game.

This is simply the best "Splinter Cell" game in the series. It gets the balance between action, freedom and stealth absolutely right. Of course, it's getting on these days, but its still fun.

Finally, after two games, the Splinter Cell series has reached its potential and delivered in Chaos Theory an exciting spy adventure. Only it's a Clancy-esque affair, so expect more military-technology jargon and less Sam Fisher taking his jumpsuit offer to impress a roster of Russian ladies.

The story is rather standard for the series. It revolves around World War Three being on the brink of starting once again and its up to Sam Fisher and his covert ways of working to stop it happening. There are linkages to the storyline of the first game, which despite only playing the original game recently, I didn't get as I was too busy battling the oversensitive AI and poor contextualised movement to notice fine details of the plot. Nevertheless, they aren't important to understand and you can enjoy Chaos Theory's story in all its predicatability without having played the predecessors.

The gameplay and level design have been improved dramatically this time around, to the point that the game still feels challenging but not unfairly so. Enemies won't spot you in pitch darkness any more, which is great. There's a fantastic sound meter instead, which shows how loud you are. Enemies will know your position just by listening, so watch out! This system makes the far more realistic and tense. And there are now multiple routes in, out and around levels, something that had no reason not to exist from the get go in my opinion. But it's here now and the game's all the better for it. You are now able to choose your loadouts before missions too, but really, I found no real reason to use anything but the Stealth option, even when I chose to engage the enemies (who can easily chop your health bar to zero if you engage more than one at a time). This option always seemed to have enough ammo and gadgetry to last me through any given mission.

There is a rating system now, which gives you impetus to replay missions and do the side objectives. These side objectives aren't token either; they expose the conspiracy afoot in the game's story and doing them sooner rather than later allows for less negotiation of armed guards later on to grab the piece of the puzzle. The pistols alternative fire now more subtly disables cameras and there's a hacking minigame now, but it's really pretty shallow once you get used to it.

I cannot ignore the fact that, graphically, this game is still a beauty to look at. While textures and fire effects, as well as the cutscenes, are actually quite ugly by today's standards, the lighting, shadows, character movement and sound effects are top notch. There is real depth in both the lighting and sounds in this game, reflected in the brilliant sound and light meters that define the gameplay.

If you have to play any of the Splinter Cells (as to stealth fans, I would still recommend any Hitman game or Deus Ex over these), make sure it is Chaos Theory. It's worth the asking price just for the Panama bank level alone.

This Game, On its own damn ground, IS THE BEST Splinter Cell you'll ever play, The atmosphere, voice acting, gameplay, story line, graphics and mechanics go so well togheter its like the meat in the ♥♥♥♥ing dinner. Alright now, being an "old Splinter Cell veteran", ever since the first Splinter Cell back in the days, I find this game the best of the series. Let me break it down for you. :)

You are Sam Fisher a loving father ever so protective over his daughter, you got a dark sense of humour, and your character is voiced by Michael Ironside, and you literally scare the hell out of anyone you interrogate. You're working for the NSA's Sub Agency called Third Echelon (Later in Blacklist 4th Echelon). And you're under the program of field operatives or mind you Black Ops then I mean the blackest of the Black Ops, callsign code "Splinter Cell" Or refference from the game, you're also known as a "Sigint Ninja" in other words a Spy. You are the most secret asset the US Government have, If you get caught or killed you officially and unofficialy doesent exist.

The Year is 2007 June: Tensions are running high between China, North Korea, South Korea and Japan, due to Japan's formation of an Information Self Defense Force (I-SDF). It was and Is a considerate violation of Article 9 of the Post-World War II Constitution, and blaming the I-SDF for information warfare attacks against their countries, Chinese and North Korean forces establish a blockade in the Yellow Sea against Japanese shipping. Because Japan is an ally of the United States, and thus the NSA's Third Echelon, the U.S. Navy dispatches a highly advanced warship, the USS Clarence E. Walsh (CG-80), to the Yellow Sea with the hopes that China and North Korea will back down at its presence.

Dont Worry No Spoilers here just giving you the same briefing as you will see in the first mission here.

You are dispatched of to a Lighthouse on the Talara, Peru coastline, To locate Bruce Morgenholt, an American computer programmer who has been captured by a Peruvian separatist group called "The People's Voice", led by El Salvadorian revolutionary, Hugo Lacerda. Morgenholt was working on deciphering the Phillip Masse's weaponized algorithms, who had been assassinated by Fisher (in Splinter Cell). The resulting Masse Kernels are being touted as the superweapon of the 21st century. Fisher is tasked with making sure they do not fall into the wrong hands.

Alright this is the very fist Splinter Cell game where the Tri-Vision Modes where introduced, WAIT, NOT Tri-Goggles but vision! In the 2 first Splinter Cell's (Splinter Cell and Splinter Cell Pandora Tomorrow), You had only two vision modes Black and White Night Vision and Thermal, However in this game it reintroduces the Night Vision capabilities with a updated, Green Shade Vision Night Vision, Pretty much the same Thermal Vision and lastly the real change the ElectroMagnetic Field Vision (EMF). EMF is used to spot Cameras and other electronical gear you can use for your advantage IE. Distractions. This is also the first title of the Series where you can use a Knife to kill your enemies with :D and also introducing certain kits you can grab with you, Foregrip Attachment (a More stable shot with your rifle) Shotgun Attachment (Secondary firing mode, ♥♥♥♥ing reks anyone near you) Sniper Attachment (High powered anti material attachment that will ONE hit anything from long range and even through certain walls!). and you can just as easily take off the attachment and go back to the Standard Launcher Attachment. Like you never had those attachments haha, But mind you gears are only presets you cant grab whatever you want of what quantity (sadly).

More to the atmosphere of the game. This game HAS AMAZING music soundtracks made by Amon Tobin. Here let me give you a link to a playlist Listen to it and you can just sense the tensity and the need of UTTER Silence and Stealth, The Mysterious aspects of this game just amplifies up. More on to voice acting. fantastic when you have Michael Ironside voicing Sam Fisher, and all of the other main characters have great voice acting, and not to mention the NPC's or Goons that you can Interrogate, hahaha alot of twisted humour here and reverse psychology and just plain trolling when Sam talks to them. Some panic and pee their pants, other tries to act tough but fails, and some are just stupid.

You will have a Stealth rating in this game and also a Sound level that you emit when you walk around according to your surroundings, like if you're in thunder storm, the ambient sound will be alot higher meaning you can make more noise without being heard than you would when being inside in a room where the sound level is far less than outside, Of course if you run like a ♥♥♥♥ing ♥♥♥♥♥♥ past a guard despite the ambient sound HE WILL hear you. What kind of flooring or ground you walk on affects how much sound you produce, when walking around and it does affect it alot. This game also introduces a new difficulty Elite Mode, Where you only have your Knife, OCP and wits to beat the levels. ALSO Controls are TIGHT as♥♥♥♥, real pleasure to move about in this game! huge plus on that.

Multiplayer? Well yes, Coop and Versus mode, in Coop you are Two Spies, dubbed "Steve and Bob", or Agent One and Agent Two, set in the same storyline as Official/Unofficial Splinter Cell's in Training you are inserted into War thorn Seol. Its in the same setting where Sam Fisher just independently played from the main campaign but you however assist Sam Fisher in completing his tasks and also taking on tasks where a lone Splinter Cell cant do the job.

Versus Mode, (2vs2) You can more or less say its a rebooted version of the Pandora Tomorrow Versus, with slightly updated Graphics and new gadgets and gear and maps, However there are not many players left in the Official servers anymore or none at all, So if you want you can sign up for this Steam Group we do have a few nights where we play Versus. here:

Graphics: Great for its time and it still has better Graphics than some modern games today.

Okay enough "Theory" crafting is the game WORTH IT? Yes definently, One of the few games without a doubt straight from the box I can recommend. But sadly there are downsides to this game. It is not moddable, but thank lord there exist alot of Map Packs for the Versus mode, and workarounds on spesific problems you may bump into. The good side again you dont need UPlay to play this game (YOU WOOT MATE, THIS IS MADE BY UBISOFT!) I know m9, this game dont have cancer like the rest of the UPlay affected games.

Pros and Cons:

-Fantastic Storyline
-Coop and Versus Mode
-Atmospheric Setting
-Superb Voice Acting
-Lots of Choices and Approaches you can do
-LAST of the Legendary Splinter Cell title that lived up to its name

-Non Moddable
-Almost no players in Versus mode

Well there not many cons with this game, But they can limit the replayability value over the course of time. Thank you for reading my review and have a lovely day, Or atleast try to make it better if you have a bad day, Cheers!

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.
