"In every Brink mission, you’re a member of an eight-man team, tasked with doing a wide variety of military objectives (rescue, search and destroy, infiltration, you name it, the list goes on and on). If you play by yourself, you’ve got seven AI buddies who are all capable of making their own decisions and doing every single action you can do. If your friends come online and want to join you mid-mission, they can jump in and replace one of those AI squaddies with their own custom character - and bang you’re playing co-op. And yes, this means you can have a full eight man co-op session. You’re all tied together through a dynamic mission system that automates communication and keeps everyone working towards the same goal."
