The previews arent really telling.. i think there is 4 players in Doom 3? How many maps? What modes? New weapons? Jeeez.. it's out in like 2 days, where are the reviews?
The FAQ on this board says 2-4 players in Doom 3 on consoles (online only, no offline for D3). Presumably the same maps as previous versions of the game since there's been nothing new announced in that area.
