    I LOVED this game for years, and replayed it so many times. But I'm gutted to say it's just too much hassle to play now. Three levels in and can't get half way through before one glitch or another from running it on modern hardware, or a machine with multiple screens, gets in the way. I can't be bothered messing around with widescreen fixes, or external tools to force windowed mode, and no one should have to. Or the way the night vision keeps glitching until you change resolution and back…

    Tested on Steam Deck OLED! Still the gold standard for Splinter Cell and stealth in general. On the Steam Deck OLED, Chaos Theory feels tailor-made for portable play. It automatically supports 1280×800 16:10, with proper aspect ratio and crisp visuals. Runs flawlessly at 60 FPS, even on max settings. Cinematics are full-speed, sound design is intact, and load times are near-instant. Menus are slightly awkward - D-pad doesn’t navigate, but the analog stick works fine. Battery life: about 6…

    A legendary stealth game. Splinter Cell stealth mechanics and levels refined to almost perfection. This review will basically act as rating boost and also so my love for this game and the series is on record here on Steam. Multiplayer is still alive thanks to the efforts of fans.

    Great game. The best Splinter Cell out of all of them. Horrible PC port that requires mods to get it running though. And even then its a gamble whether the game will boot up sometimes. It should not be the consumer's job to get something they paid for running. Had I known I would have just torrented it. It is not a crime to steal from Ubisoft.

    The DEFINITIVE Splinter Cell game. After SC: Pandora Tomorrow, I expected SC: Chaos Theory to feel more like a DLC to its predecessor..... It's safe to say I was entirely wrong. This is the best Splinter Cell game anybody will ever play. It does everything better than the last two instalments. Gameplay has been refined with a comb, allowing you to play with a more versatile approach. For starters, before getting into a mission, you can choose whether you want to go in with a stealth or combat…

    This is peak Splinter Cell. That is it. There are no other entries in the Splinter Cell series that even come close to what this game did in terms of gameplay, aesthetics, story, mechanics. For a dark, stealth shooter with high levels of realism - I would even say this game is peak for the entire stealth genre if those qualities are what you are looking for.

    This, right here, is peak Splinter Cell. No game in the series is better than this one, despite this one still having its flaws. Graphically, this game may have aged in texture and model fidelity, but the shadows are top-notch. The gameplay is similar to SC 1 and Pandora Tomorrow, but refined to its limit. Pandora Tomorrow might have conceptually cooler levels, but Chaos Theory has significantly better execution. Gone are the forced combat sections, mostly anyways. The gadget selection is…

    So, this is the MGS3 (both in number and quality) of the series. Massive improvements to stealth, gameplay, and mechanics. A gripping story with a great blend of seriousness and humor. Fantastic level designs, interesting mission objectives, and it even has bonus objectives (though that only appears to affect ranking which offers little else than to stroke your ego). We also get loadout options (though it’s mostly assault vs stealth) to give a greater variety to playstyles. There are more…

    This game is as fun as it was for me back when I was playing it back in 2005. This review is more to discuss it's playability on handheld consoles. The game runs just fine on my legion go s. There are multiple controller layouts made by the great steam community. If you are on the fence about it's non steam deck verified status, rest assured it works just fine.

    Valve claims Chaos Theory isn't Steam Deck or SteamOS compatible, but I can confirm that it works very well and there's a custom controller layout that makes the game almost 100% playable on gamepad with my Ally running Bazzite. The only issue you'll have is the map screen can't be rotated outside of changing camera angles in game. Still one of the best stealth games ever created.

    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.

    This game is amazing, IF you can get it to run. I have played this game numerous times but never on the Steam version. This sucks, can't even start the first mission without crashing. Tried many fixes online, nothing works. I will be refunding this. Even for 75% off, it's not worth it to buy a game that doesn't work. Avoid buying this unless you can get it working.

    Classic Ubisoft man. This was my favorite game in the series and I have been desperately wanting to replay it. Can't change the settings, start a mission, or even open the menu without it crashing. Good thing I got this for under 5 dollars or I would be extremely pissed off by the fact that I was sold an unplayable game. You'd be far better off either getting an original Xbox, a 360 or even just an Xbox altogether and just using the disk.

    I finally played Splinter Cell: Chaos Theory, apparently for many players the best game of all time. Personally, I wouldn't go that far, but I definitely enjoyed it a lot. Although it's an old game, it still has all the important mechanics we modern gamers need: tutorials, classic level design, an understandable interface, typical keyboard controls, etc. So don't be afraid that the game has aged badly. The gameplay here is great and very different from other stealth games. The enemies…

You essentially play it without touching any enemies unless impossible. - First mission, have to take out the Lighthouse guy - second mission, kill Hugo (doesn't show up on your kill count). - Fourth mission, have to interrogate a one guy. - Sixth mission, kill Milan Nedich (doesn't show up on your kill count). Otherwise you can do every other mission with 0 on…

    "Yeah, I'm the real kind. Not the tuxedo kind. " Chaos Theory is still very worthwhile, but it has aged with a handful of sharp edges that can make the experience quite unpleasant. The level design mostly holds up, the interrogations and Michael Ironside's performance are still charming and funny (perhaps the best thing about the game), and the cheesy, cartoonish plot is adorable. I laughed out loud at one of the early descriptions of one of the villains being something like, "Imagine Che…

    The hardest part about this game is making all of the settings work. I have messed with the shaders on several different levels and everything is so inconsistant. It's probably a good game, but I'm at the New York level and it looks like I just got flashbanged every time I turn on night vision no matter what I do. If you buy this, be aware that you are going to need to do some modding.

    TLDR: This is a great game that has no tutorial. And it really needs a tutorial. If you're unfamiliar with Splinter Cell, be prepared to read the manual. I'm honestly on the fence about recommending this game. Let's get into why that is. Tom Clancy's Splinter Cell: Chaos Theory is a classic stealth game that puts you in the shoes of Navy SEAL officer Sam Fisher, who is equipped with a whole bunch of cool gadgets like night vision, thermal and EMF goggles, surveillance cameras, and some more.…

    Tom Clancy’s Splinter Cell: Chaos Theory is one of the best stealth games ever made. It gives players real freedom to approach missions quietly, use gadgets creatively, and decide how much force to use as Sam Fisher. The light-and-sound stealth system remains satisfying, while the detailed levels encourage patience, exploration, and careful planning. Its co-op mode is also excellent, creating tense missions that require communication and teamwork. A few controls and visuals show their age,…

    I played this game 20 years ago already. And a week ago I decided to replay it. It's a great stealth game with a capturing story. In fact, more than half of story and missions I could remember, which says how good it is. It's a stealth game and I would like to compare it to Hitman. The gameplay itself is very simple. You sneak your way through levels, taking out enemies, getting or achieving objectives in some location of the level. Many times, the game provides you two (sometimes even more)…

    Many would refer to this game as the epitome of the stealth action genre in video games. With a deliberate slow, methodical, almost sim-like flow to the mechanics, and coupled with an expressive Amon Tobin original soundtrack; this game has yet to be surpassed or even imitated in its systems and aesthetics.

As always, the game starts with an epic opening, but this time, unlike the others, it shows both stealth and assault gameplay, while the music changes depending on the playstyle being shown. For me, it’s one of the best openings in the series, at least up to the third game. After that incredible intro, we’re greeted by a menu that instantly gives me pure nostalgia.…
