"The Xbox though is a system that stays the same, which made it a little more challenging to get everything we wanted to get in. We still took the time though to make sure that we had the cooperative campaign in, which is the first time that you can play Doom 3 in a co-op mode. All the other modes like deathmatch and team deathmatch are all included in the Xbox version that can be played either through system link or Xbox live."

"Although the single player game is more or less the same as the PC version, there has been one major addition to the multiplayer side of things. Players now have the option of teaming up and battling Hell's minions via Xbox Live or system link, a feature that's extremely entertaining for a number of reasons. Unlike many games, you don't need to play through the single player portion of the title if you want to play cooperatively, you can simply hop on Live, find a partner, and choose the level that you want to play. While most of the single player levels made it into the co-op mode, nearly all of them have been reworked to make the experience more enjoyable for multiple players. The layout is a bit different, and monsters spawn in different areas, so it's almost like you're playing a new and original game."
