Infinite Crisis, developer Turbine’s take on the multiplayer online battle arena genre featuring heroes and villains from the DC Universe, will launch its open beta on March 14. Turbine announced the upcoming PC title’s open beta start date at an event yesterday, alongside reveals of three new characters: Green Arrow, Aquaman and Mecha Superman.

Infinite Crisis is a free-to-play MOBA game, a genre that has exploded in the last few years with titles such as Riot’s League of Legends and Valve’s Dota 2.

In the last ten to eleven months of development, Infinite Crisis content has drastically increased in size, Executive Producer Jeffrey Steefel claims. “We now have three maps, three modes, a huge amount of different ways you can play the game. Twenty-seven characters and, in fact, we are adding a new character every three weeks.” Steefel also outlined a plan to launch new costumes for existing characters every week.
