Via een recente post op de website van Killzone.com is bekend gemaakt dat het developers team momenteel bezig is met het testen van de multiplayer van Killzone 2. Op de officiële website lezen we onder andere het volgende:
“Me and my boys have been mostly busy testing Online this past week and making sure that the rewards and ranking are working as intended as well as checking the collision and geometry for MP02, also known as “Road Block” currently, but I’m sure it’ll get a much more exciting name before release. I can’t really give you much in the way of details about Multiplayer otherwise, eventhough I am itching to share it all with you. I guess you’ll have to wait a wee while longer though.”
