The two players have three minutes to clear seven swarms of rogue battle drones, a total of 24-26 enemies. Bosses must be fought in order to complete the seven swarms, the bosses are rogue prototype bots holding prototype weaponry such as the Titan. The bosses are fought during waves three or four and seven.
Update:Recently ngmoco has made an improvement to ACCURACY of every drone in the game to make the game mode more challenging and fun, so you will have to get running/dodging or be shot down. Avoid being trapped by groups of drones! Drones armed with AMJ/Vaporizer/Auto Rifle have become a bigger threat now! Careful out there!
There are six CO-OP Maps, Annex, Junction, Courtyard, Rooftop, Factory, and Warehouse. These are different from PVP maps in that there are no powerups, and you always respawn at the same place. In All Maps, the enemies will converge onto the main room, however, it may be faster to try to anticipate the enemies by going off to the side rooms. Beware, this does take time, and Co-Op can be completed without venturing from the main room in the alloted time
