Arkham Asylum has been taken over by super-villains Poison Ivy, Mr. Freeze and Scarecrow. Batman summons the Heroes in order to bring the situation under control, while The Joker hires Villains to find out what is going on in "his house" and why he wasn't invited to the party. The asylum consists of four wings. Players need to talk to the inmates outside each wing to open it and they can do the first 3 in any order they wish. It is a hard alert with medium difficulty and should not be attempted without each person having a few Tier 1 pieces.
