Closer-than-ever stealth system that lets you hide in the darkness inches away from bad guys

The funniest guards of any stealth game (apart from Metal Gear)
Pipe-climbing, vent-crawling, ledge-shimmying, shadow-sneaking action
And more

Ubisoft gets:
your money ($2.49 on sale)

You will need to patch the game a little bit, but so long as you follow the pcgamingwiki page on Chaos Theory to a T, you'll be playing no problem.

You'll want to put "-nointro" into the steam command line (accessible by right-clicking the game and entering its settings), the widescreen fix on thirteenag (linked on pcgamingwiki), and you'll want to disable mouse acceleration by going to the game's "System" folder, opening "splintercell3settings.ini", and editing all instances of "biasCut" to "biasCut v=0.0" (use the Find tool in notepad to locate all instances of biasCut).

If you want to get co-op working, use RadminVPN or any other software like it to set up a LAN party network. You'll want to disable the widescreen fix though, due to the fact it messes with the other player, at least in my case.

My only problems with Chaos Theory is that it is old, a few parts of levels are broken or buggy; the AI can have really dumb moments, but at their best they'll use teamwork to clear a room, at their absolute best they'll 360 noscope you like a Counter-Strike spin bot, punishing you for going too loud in a stealth game with absurd hilarity; some of the levels are less inspiring than others, but that's up to preference; the story isn't amazing, but at least it isn't trying too hard to be serious like other entries in the franchise.

There are few feelings greater than coming back to Chaos Theory and knowing a level like the back of your hand, breezing through it, slowly, smoothly, and quickly, without saving your game once. That's the bank level for me, and I'm proud to say I stealthed that level around 10 times before I became so used to it I could beat the whole thing without a guard even becoming curious.

Play this game. One way or another, you'll be wearing night-vision goggles and crab-walking through banks, boats, and batteries soon enough.
