Gazillion Entertainment has announced that its massively multi-player online action role-playing game “Marvel Heroes” will launch worldwide June 4.

The free, downloadable game will be available initial only for PCs, with a Mac version following post-launch.

Fans will have the chance to play as Iron Man, Wolverine, Hulk, Spider-Man and other Marvel characters as they team up to stop Doctor Doom from devastating the world with the power of the Cosmic Cube.

“When we started working on ‘Marvel Heroes’ we knew exactly what we wanted to make–an unrivaled multi-player free-to-play action-RPG experience that allowed gamers and comic fans to play as their favorite Super Heroes,” says David Brevik, president and chief operating officer, Gazillion Entertainment. “This is an incredibly exciting day for all of us at Gazillion, and we can’t wait to let gamers experience the ‘Marvel Heroes’ world and our fresh take on the massively multiplayer online genre.”
