Robin's Hood: Harley Quinn's Revenge Trailer Goes Batty 

Sometimes, it's easy to forget that sidekicks have a purpose. They are, after all, easily kidnapped by arch-nemeses, generally ineffective unless dwelling in their natural habitat of the hero's shadow, and rarely capable of putting together a costume that doesn't implicitly beg for a super-powered swirly. I have to say, though, that Batman: Arkham City's Harley Quinn's Revenge DLC looks pretty promising. Robin's doing his best Ezio impression while searching for his missing Batmentor, and Harley Quinn seems to have completely lost it, which has apparently put her in a bit more of a murdering mood than usual. Admittedly, the "Payback's a bitch" tagline seems a bit ill-advised given Arkham City's less-than-savory history with the word, but the rest looks rather impressive. Grapple past the break for the full trailer.

The DLC's release date is still sadly TBD on PC - especially given that it's not even dropping on consoles until September outside the US. And so, at this point, we can only watch, wait, and be ever vigilant. Or we can tab back over to Diablo III.
