CVG's interview with Ricardo Bare, lead campaign designer of BlackSite: Area 51, about PS3 version, AI, Halo 3, co-op, new demo and more.
From the interview:
CVG: What can you tell us about the co-op mode?
Ricardo Bare: It'll be like Gears of War. You can have one friend join the game with you at any point and play through the game together. It'll be the same features as the single-player campaign; your squad will still be there. Player one is the squad commander and player two is an extra special forces soldier.
