It’s hard to be a metal face. Agent Cobalt has learned as much after finding the Space Exploration Foundation’s lost colonization ship The Seed at planet X9CSEC5.5B-blue, Trunkopia. It was once built by a one million strong development team back on Earth, but disappeared merely 30 minutes after its subspace jump. Whatever happened on board during its misadventure, sanity was not invited.
Cobalt is an action game of running, jumping, rolling, shooting, throwing, dancing, hacking, rolling, flying, sliding, climbing, looting, deflecting, racing, piñata-ing, passing, scoring… and even more rolling! Play cooperatively with friends or defeat your enemies in a death match, loot match, race match, or Capture the Plug matches. (Or one of the other game modes, of course!)
The game is initially developed for PC platforms Windows, Mac and Linux. The Windows version will be released first.
