Re: Overlord II Demo Takes Over Your Xbox 360
According to gamestop's website
# Two of the multiplayer games are Co-op:
* Arena Survival – Two players, both as Overlords with their own minions, help each other stay alive as they battle against wave after wave of enemies coming at them in an arena setting.
* Kill A General – Two players, both as Overlords with their own minions, go through a series of lands together on a mission to kill a Glorious Empire General.
Doesn't sound like the main campaign will be co-op, but the "Kill a General" mode also sounds like it may be it's own campaign. Also, this is from gamestop, so it may be entirely wrong.
I must say, based on the demo, this game is even better than the original.
