The four-player, co-operative, multiplayer mode received acclaim. Gaston said it was a "watered down version of Left 4 Dead", but it was nonetheless a fun and pleasant experience for most players. De Matos said the game had encouraged players to work together to defeat enemies and to plan before attacking, which he said had turned the mode to a "gratifying" experience. He criticized the game's difficulty, which he said does not scale well, and the scripted enemies, which made the game less dynamic. Whitehead highly recommended the co-operative mode, which he thought should have been the game's main focus. He added that it provided more freedom to the players than the campaign.
