Just Cause developer breaking into downloadable games with co-op shooter for Xbox 360, PlayStation 3, and PC this fall.

Avalanche Studios, the Swedish developer behind the Just Cause series of open-world action games, is branching out. The developer has already explored the free-to-play social gaming space with The Hunter, and now it’s trying its hand at downloadable games with a new intellectual property.

Sega today announced that it will publish the developer’s first downloadable game, Renegade Ops for the Xbox 360, PlayStation 3, and PC. Set for release this fall, the cooperative shooter will see players commanding a variety of vehicles as they rain down destruction on a terrorist group headed up by the matter-of-factly named Madman Inferno.

Renegade Ops will let players form commando teams of up to four players online, though it will also support two-player split-screen on a single system. Although the game is being designed as a co-op-focused shooter, it will also include a single-player mode.
