I thought you can only play the Splinter Cell: Chaos Theory, Multi-Player through XBox Live! Or can you also play it on system link? Aside from that, I'd recommend Ghost Recon 2: Summit Assault for a good Multi-Player game. In comparison though, Ghost Recon's movement is a lot different. As in more realistic, and you actually have to use some sort of tactics in the game in order to survive. If you hate those types of games, then I take back my recommendation!
