The most important change comes with how the game selects players to go up against each other. Instead of the randomized setup in Pandora that could potentially put a first time player against three competitors with hundreds of hours under their belts, Chaos Theory will pit players against each other based on how long they've spent with the game. "Splinter Cell Pandora Tomorrow was a deep and complex game," says Mametz. "That means that you had a lot of things to learn before facing other players. One of the big difficulties of Pandora Tomorrow was that during your first sessions, you could fight players who were much better than you...in Chaos Theory, beginners with a similar 'played time' will be placed together when they search for a session."
