Well, we may not be getting co-op gameplay , but Guerilla Games is considering another significant enhancement.
It seems that many Killzone 2 fans really want a party system for the online multiplayer; this will allow us to hold groups together as we pass from map to map. It's a feature that most avid participators would appreciate and thankfully, it appears that Guerilla may indeed add it at some point in the near future. According to one of the team's latest Twitter updates, the team is "investigating" the option and we hope to hear more about it soon. Here's the exact wording of the update- "We're investigating various possibilities for implementing a party system." Doesn't get much more straightforward than that, right? Most will agree that an online FPS without this feature is kinda irritating, and you can trust us when we say Guerilla isn't about to sleep on updates and patches for the KZ2 multiplayer experience. The new maps are great, but if you want to keep yelling at 'em to make things better in certain ways, we're confident they'll listen. We didn't get co-op, true, but has there ever been a time in the past year where the developers weren't fairly up-front with the gaming public? We think they've been pretty darn forthcoming, actually.
So we'll be on the lookout for the possible addition of a party system. We don't know a thing about the technical angle of this, but we'd like to think it wouldn't be that immensely difficult to implement such a feature.
