Muse Games today announced the launch of Guns of Icarus Online, the first co-operative airship combat game mixing together first-person shooter action with team-based strategy. Up to four people will crew a ship, taking on one of the key roles of Captain, Gunner, or Engineer, and battling it out against other ships above the post-apocalyptic waste. In Guns of Icarus Online it will take teamwork and tactics to dominate the skies.
