Gazillion Entertainment's self-proclaimed "Action-MMORPG" Marvel Heroes officially launched this morning for PC, following a brief early access period for pre-ordering players, and can now be found free-to-play via marvelheroes.com or on Steam.

Created by David Brevik, the visionary behind Diablo and Diablo II, Marvel Heroes lets gamers suit up as their favorite Marvel Super Heroes, including Iron Man, Thor, Wolverine, Hulk, Captain America and Spider-Man, as they battle through an extensive original story crafted by Marvel super-scribe Brian Michael Bendis.

“For over three years we’ve been building Marvel Heroes to be an exciting, free-to-play massively multiplayer action game, and we are ecstatic to finally put it in the hands of Marvel fans and gamers alike,” said David Brevik, President and COO of Gazillion Entertainment. “The creation of Marvel Heroes has been a labor of love. As a die-hard Marvel fan, it’s an honor to give players the chance to take on the roles of their favorite Marvel Super Hero in an epic adventure.”

At launch, Marvel Heroes will feature 21 Super Heroes, each with unique and extensive leveling systems, power trees and equipment. Players can choose to wear costumes from over 70 years of Marvel history, including costumes from Marvel’s recent theatrical blockbusters Marvel’s The Avengers and Iron Man 3. At any time, players can swap between their favorite Marvel Super Heroes on the fly. Set across diverse locations from the Marvel Universe, Marvel Heroes offers fast-paced, action-packed game play with a robust crafting system, intense player-versus-player (PvP) combat, End Game, and much more.
