Killzone 3 is sounding better and better with each passing week. According to the developers, Guerrilla Games, Killzone 3 will definitely support split-screen co-up, but there has been no official work about online co-op. TheSixthAxis contacted a trusted source to learn that the game will support both online and offline co-up.
The trusted source had the following anonymous statement:
“Guerilla Games wanted to improve on Killzone 2 in every way, which means campaign co-op. Both online and offline.”
Until we get official word from Sony / Guerrilla games, we’ll treat this as a rumor for now. Needless to say, you can expect lots more news between now and February 2011, when the game is released.
