To coincide with the release of the Game of the Year Edition for Batman: Arkham Asylum in the US today, those that already own the game can now download two more add-ons.
The Dem Bones Challenge Map, previously only available with GameStop pre-orders and the Crime Alley Challenge Map, previously only included with the collector’s edition, are now both available on PSN and XBL.
Both will run you 240 MSP on 360 and GFWL with Dem Bones being called the Villain Challenge Mapon PC, per Shack.
PS3 users will get the maps through the PSN update later.
The Joker Challenge Maps and Prey in the Darkness are still exclusive to PS3.
