Warner Bros. Interactive Entertainment has announced that the open beta testing phase is now underway for Infinite Crisis, the free-to-play MOBA game based on the roster of DC Comics superheroes and villains.

Infinite Crisis is the highly anticipated, free-to-play multiplayer online battle arena (MOBA) with a robust lineup of DC Comics Champions, including Batman, Superman, The Joker, Wonder Woman, and more. With Open Beta, Green Arrow, Aquaman and Mecha Superman join the cast of characters that fans can choose to play.

In Open Beta, players will be able to test their skills on three different maps including the recently announced “Gotham Divided,” a tri-lane map where two universes collide and players can battle across Gotham City and its Multiverse variant, Gotham by Gaslight. Since the beginning of Closed Beta in 2013, Infinite Crisis has gained an enthusiastic fan base and dozens of Champions have already been revealed, offering bountiful choices to players of all skills and styles.

Signups can be found at the official website, and the team has revealed a new trailer to help rally the troops, which you can check out below.
