Guns of Icarus Online is an upcoming co-operative online shooter where you and your team pilot and fight from your airship against other airships, all set in a post-apocalyptic, pseudo-Victorian Steampunk era. It's a sequel to the indie hit Guns of Icarus, except now, as an MMO, a server can handle many players flying in the skies at once, all vying for territorial control of resources.
Players choose from a variety of classes such as Pilot, Engineer, Gunner, and Captain. Each have their own special abilities such as Engineers who have the ability to resurrect dead team-mates and the Captain who has the ability to rally the team. The team has to work together on their ship in the sky if they're to defeat their enemies.
