The upcoming September update for Infinite Crisis is only a few days away, and it's one of the biggest we've seen so far.

Two new champions, Nightmare Robin and Atomic Joker, are making their way to the roster. In the video above, we sit down with Cardell Kerr, creative director for Infinite Crisis, and break down their abilities and roles on a team.MOBAs are a difficult genre to jump into, so Turbine revamped its tutorials and added a coaching mode to get new players into the action faster, while adding more context about the conflict in the DC Universe. Tutorials still explain the basics of gameplay, but they're also interjected with cut scenes that help ground you within the game's fiction.So, if you're like me (a MOBA fan who doesn't know much about DC), you can either accept the crash course or skip it. If you're coming from the other side, the familiar characters and story arcs can ease you into a traditionally difficult kind of game.The new coaching mode offers more in-depth training for those who want it. Say you want to play a bruiser type of champion. Superman, who's a bruiser himself, will walk you through how to play that role. It's not specific training for one champion; it's information about how to thrive within your spot on a balanced team.You can download the Infinite Crisis September update on September 24.
