Details about Battlefield 3's co-op mode have been sparse as developer DICE has kept quiet on the subject. But thanks to the Jr. Product Manager at DICE, Tommy Rydling, their silence has finally been broken. BF3's co-op will have a pick-up and play gameplay style, similar to the way they have built BF3's muliplayer. It will be important to stick together, "You fight together. You die together. And you score together."
"For the most part, the missions in the co-op campaign are asymmetric. This means that one mission can have you piloting a helicopter while your friend is the gunner, for example. Other situations have one player disarming a bomb and the other one defending him. Or (as you could see in our press conference play through at gamescom) you can do tandem kills to avoid detection. There are also other mechanics requiring teamwork, such as spotting enemies to make large firefights easier, or the essential concept of reviving one another to avoid ending up at the game over screen."
It sounds a lot like the way I played Battlefield: Bad Company 2's co-op in team missions like Capture the Base. I spent way too much time playing BF:BC2 so if my feelings are correct, I'm in. The way co-op mode is actually set up sounds like the team based co-op modes in SOCOM 4. Either way, I'm sold.
Battlefield 3 co-op will take place in the same world as single player. Co-op follows its own unique story though. Unlike in single player, you won't be assigned to any official rank or position in the Armed Forces. This was intentional; they want to make sure you'll be able to take on as many badass rolls as possible.
Battlefield 3 will be released on the PC, Xbox 360 and PS3 on October 25, 2011.
