Guns of Icarus Alliance is the expanded and definitive edition of Muse’s flagship title Guns of Icarus Online, the original player-vs-player steampunk airship combat game. Alliance features all of the content from the original title, but with the addition of player-vs-environment cooperative experiences, an ongoing war between six elite factions vying for control of a world ravaged by machines, and an ever-changing world that is constantly being shaped and reshaped by the players. With a good ship and the right crew, you can conquer the skies - and maybe even the world!
