Warner Bros. Interactive Entertainment this morning launched the PC open beta for Infinite Crisis, the free-to-play multiplayer online battle arena game from Turbine. It's been in closed beta for the past 10 months.

To coincide with the launch, Warner Bros. has released a new trailer titled "What Do You Fight For?," which you can watch below.

Announced nearly a year ago, Infinite Crisis features player vs. player battles set within the DC Multiverse, where gamers can control different incarnations of their favorite heroes and villains. The open beta features three maps, including "Gotham Divided," and 27 champions -- Nightmare Batman, Shazam, Wonder Woman and Gaslight Catwoman, among them -- with new additions Aquaman, Mecha Superman and Green Arrow.

Players can sign up on the game's website.
