Here's the latest character trailer for Infinite Crisis, the free-to-play MOBA, with the Boy Wonder himself set to make an appearance this Wednesday 18th in the free-to-play game's open beta.
According to Warner Bros, "As an acrobatic support, Robin empowers his allies and disrupts his enemies with devastating team-fight setups."
So he jumps around a lot and lets other superheroes punch people for him. Sounds about right. Here's some more screenshots.
