Eidos has announced that pre-ordering Batman: Arkham Asylum from GAME will grant you access to a special Villains Challenge Map.
The game, which is out on 28th August, sports numerous challenge levels in addition to its main campaign, and these generally involve fighting waves or enemies or taking down scattered guards on patrol.
In this one though, "Batman must descend into the depths of his own nightmares and come face-to-face with The Scarecrow and his army of skeletons." Ooh.
You can get a sense of that in our Batman: Arkham Asylum Villains Challenge Map screenshot gallery, where you can see Scarecrow strutting his stuff.
If you fancy seeing Batman do that, perhaps you'd like to read one our innumerable previews, like the most recent one?
