Gazillion Entertainment throws open the doors to Marvel Heroes this weekend, giving Iron Man fans across the country a chance to slip into a Stark suit and do some damage, Diablo-style.

All a prospective hero has to do is register at the game's official website and they'll be in. The open beta event for the free-to-play PC game runs from tonight at 10PM Eastern time to 1PM Monday morning.

It must be nice, gearing up for the launch of a game that has ties to the first blockbuster action film of the year. If Gazillion can't get at least that many folks playing during the height of Iron Man fever, then they're doing it wrong.
