Not to be confused with the recent LEGO Marvel Super Heroes game, Gazillion Entertainment has revealed a launch window for their upcoming MMO Marvel Heroes, debuting sometime in the American Spring (Autumn for Australia). The game will be launched as a free-to-play title for Windows, however players looking to get in early can do so by signing up to the new Founders Program that offers three individual packages ranging from USD$20.00 through to USD$199.99 for the more determined.

“Our team is hard at work to make sure Marvel Heroes is true to hardcore players, Marvel fans and the most casual of gamers through deep, MMO action-RPG gameplay, an expansive interactive storyline and easy-to-play experience,” said David Brevik, president and chief operating officer, Gazillion Entertainment. “We’ve built Marvel Heroes from the ground up to be a free-to-play game where players can find and collect nearly every hero and costume in the game just by playing. The Founders Program gives players the opportunity to play as their favorite hero from the day we launch in addition to enough in-game currency to buy more heroes and costumes as we release new content.”

Marvel Heroes will be available as a Windows download to begin with, but a post-launch effort is looking at bringing it to Mac as well. You can check out the official website for more information.
