The team bills its game as the "first cooperative airship combat game mixing together first-person shooter action with team-based strategy." Crews of up to four players may band together on a ship, filling the Captain, Gunner, or Engineer roles and taking on other crews in the post-apocalyptic unfriendly skies.
Muse recently added a spectator mode, costumes, achievements, stat tracking, and friend lists to the game. The firm has also produced a launch trailer, which you can view after the cut.
