The next Killzone game is the first not to be developed by series creators, Guerrilla Games. Instead, Gamerzines has learned that they have passed on development to Sony's Cambridge studio. While fans of the excellent Killzone Liberation for PSP may be disappointed to hear that Guerrilla isn't working directly on the game, senior producer Steven Ter Heide told the site that "we'll still oversee it because the universe is something we've built up, we know the war and the rules that have been established, but they're driving the development."
