Spotted in the wild was footage of Killzone 3 with split-screen action going on, featuring players as story characters Sev and Natko facing each other.
It would appear that Killzone 3 is packing co-op but in what exact game mode isn’t known. It could be co-op in campaign, multiplayer, offline or online.
A leaked image clearly shows the two main story characters bogging at each other via a split-screen, so does this 99% confirm Guerrilla Games have story co-op? Maybe.
