Starbreeze Studios, makers of the Riddick FPS and owners of Payday devs Overkill, have announced a new co-op FPS based on Smilegate’s F2P mega-hit CrossFire (pictured above). How big a hit? Up to six million players online at once big. I’m familiar with South Korean developers making free-to-play versions of western FPS–and still fascinated by Counter-Strike Nexon Zombies–but can’t think of many times it’s gone the other way. Fingers crossed their CrossFire embraces the original’s weirdness.
