If you weren't sold by the previous demo of TimeShift, you may want to check out the new demo available on Xbox Live Marketplace. The new demo includes the same single player section from the previous demo, but the real meat is the addition of multiplayer. Several game modes are available, though we were unable to find a game when we tried earlier today. If you've got the hardware, system link is available, too. If you haven't tried TimeShift, you may want to give it a go, as the time control elements are also a part of its multiplayer. Then again, maybe you're too busy playing Assassin's Creed.
