3D gaming isn't the only new feature in Killzone 3's bag of tricks – this time around you can shoot up stuff with a couple of friends, too. According to the latest episode of FirstPlay, a UK-only show that is available weekly via the PlayStation Store, Killzone 3 will feature "a special objective-based four-man co-op mode to go with the standard two-player stuff."
Although that's not a whole lot of information to go on, it's good news for co-op fans – especially if it turns out to be anything like Battlefield: Bad Company 2's recently-released Onslaught mode, which is also a four-player objective-based co-op mode. Whether Guerrilla Games has something more substantial in mind remains to be seen, but based on how aggressive the developer has been in pushing the PS3's hardware, we're looking forward to checking it out. We'll bring you more on Killzone's 3 multiplayer just as soon as we possibly can.
