Guns of Icarus Online flies this August for PC and Mac, using Steam power

Guns of Icarus Online, a steampunk airship combat simulator, which was shown this past weekend at PAX East, will launch sometime in August.

"We plan to be in closed beta until middle of July, then we'll be opening the game up to more players," Muse Games founder Howard Tsao told Joystiq. "And our current target launch date is middle of August for PC/Mac on Steam."

The game features a class-based crew of four flying airships, using a variety of gun emplacements and airship types to blast others out of the sky. The methodical PvP battles are expected to support 32 players.

Tsao tells us the closed beta, which should be ready in a couple weeks, will invite Kickstarter supporters, with info on more invites posted on their site as capacity grows.
