DICE executive producer Patrick Bach has confirmed with UK publication PSM3 that Battlefield 3 will include ten maps for its dedicated co-op mode.
Details on Battlefield 3's co-op mode has been scarce, but Bach has said that the co-op mode ships with ten maps and is designed for two players. He would not say anything else. However, now that they've started talking, perhaps DICE will make a formal announcement soon.
Battlefield 3 is out October 25 on PC, PS3 and Xbox 360. A beta's scheduled for September.
