Muse Games has released a new gameplay trailer for Guns of Icarus: Online, the sequel to the original dieselpunk shooter where players can fly around in planes and zeppelins shooting at each other. The game focuses on multiplayer airship combat with players filling different roles on the ships carrying out various duties. A closed beta for the game is expected within the next two weeks or so, according to the game’s official website, and the developers told Joystiq it expects the beta to last through July and hopefully see a full release sometime in August on Steam for Mac and PC.
