How Can You Argue With More Batman: Arkham Asylum?

Already. Fine, Eidos have got you covered with a further two, free, challenge maps for the excellent super-hero game.

The two new maps, launching this week, will focus on the Freeflow Combat and Invisible Predator aspects of Arkham Asylum's gameplay. The former map is entitled "Totally Insane" and will see you spurning dozens of escaped prisoners. The latter map is entitled "Nocturnal Predator" and will place you in the dark with a bunch of the Joker's henchmen.

It's not a lot, but we admire Eidos for giving away so much content for free.
