Splinter Cell Chaos Theory is the third game in the Splinter Cell franchise. Picking up where the previous game left off, Chaos Theory takes on the features that made its predecessor a great game. The visuals are stunning for a 2005 game. The lightning effects are probably the best. The game is all about stealth. You play Sam Fisher, a secret agent who goes in when things aren't going well for the government covert operations. Thus, many of the missions are in dark scenarios, in which you HAVE to take advantage of shadows and blind spots to approach your enemies. They will hear any sound that you make, and that couldn't be good. So you need to walk slowly to them. This has been around since the first Splinter Cell game, but it is so much realistic with this one. This game introduced several new multiplayer modes that certainly help build the popularity of these games in terms of multiplayer capabilities. The game is quite long to finish if you play it on hard. It gets kind of frustrating at times that you have to do everything so slow to not get killed, but I guess that if they hear you, you're dead.
