Batman: Arkham Asylum (GOTY)
Get ready to visit the Asylum and all of its inhabitants. Batman: Arkham Asylum has only one quest for you - to stop the Joker. But this time you're in his territory. Having all of his allies in the asylum, can you fight through all of them and get to the mastermind still capable of stopping him?
Although the hack and slash game has only a 3-button combat system, Batman gets numerous gadget abilities (that will have to be unlocked of course) that he can use when fighting Joker's allies.
