"After four intense games, it’s time to give the Helghast and ISA forces a break. Indeed, Guerilla Games has already hinted that they are preparing to move on to a new IP. However, the universe is still expanding with the live action short that recently released, as well as the novel Killzone: Ascendancy. It would be a shame to leave the game side dormant for too long, so we look ahead to the future with what we’d enjoy seeing in Killzone 4."
