Killzone 2 had rumors of co-op DLC before it was officially released. Now that the game has been out for nearly 2 months, Guerrilla Games has decided to lay that rumor, hope, or legend, depending on how you see it, to rest. Hermen Hulst of Guerrilla Games had this to say regarding a co-op mode:
“We looked at all the different flavors of co-op early on, but decided our first priority would have to be the single-player experience and the multiplayer,” Hulst informed Game Informer. “Rather than just tack on co-op, it would have to be integrated and done to a similar standard as the single and multiplayer.”
“Having looked at it again now. I do not think we would want to add it as DLC,” he said.
Disappointed? It’s ok. Killzone 2 is still one of the best games of 09 and this generation as a whole. And Hulst’s high standards for co-op implementation are actually a relief, and show that if Guerilla does decide to do co-op, they’ll do it right. New DLC is being released on April 30th as well. We’ll be sure to keep you up to date on this topic, so stay tuned!
