We haven’t the slightest idea what the free Batman: Arkham Asylum DLC is -- other than it’s downloadable and it’s content -- but here’s one confirmation: it’s hitting all the platforms the game graces simultaneously. See, PC people? Eidos is demonstrating that the world is not such a cold and shallow place for your kind.
The multi-platform release confirmation comes from the official Batman: AA message board, in a topic devoted to the DLC’s release. An Eidos representative (and moderator) swooped into the conversation and wrote, “I'm happy to inform you, it will arrive at the same time.”
We’re guessing that “free” thing applies to the PC as well.
I’m still bitter, nay, deeply saddened, that I didn’t get a straight jacket, but at least there’s some other free stuff heading my way. Look forward to an announcement of the DLC, hopefully, in the near future.
