Doom 3: Resurrection of Evil
DOOM 3: Resurrection of Evil returns the player to the destroyed UAC facilities on Mars, this time to find a beacon within the ruins. This expansion provides players with new challenges, enemies, maps, weapons, and now multiplayer can go up to 8 players at a time.
The Xbox release does not go up to 8 players at a time for multiplayer. However, there are new and different maps to play against one another via split-screen, System Link, or Xbox Live.
