Killzone: Shadow Fall has been completed with a new co-op mode which has four players fight against massive waves of AI soldiers. The goal is to reach a certain score (1500, 3000 or 10000 points depending on your initial choice) by defending positions and shooting enemies. Things can quickly become pretty hectic, particularly when you only team up with one friend, as proven with our two gameplay videos inside.

@nostradamus: I played cross-play in 1989. Amiga + Atari ST with null modem cable in Populous and Stunt Car Racer. That's almost 30 years ago, and the industry's not moved much further since then. (13 Hours ago)
