Arkham Asylum is reinstated by the Wayne Foundation with Hugo Strange at the head and head psychiatrist Harleen Quinzel. Sparks fly between her and Joker and they orchestrate a breakout with multiple criminals making factions as they slowly take over Gotham. The takeover causes the origins of people like Harvey Dent and Victor Fries. The police hold on to the precinct firmly. Batman goes after the bosses after stopping an arms deal between Penguin and Black Mask. When Batman finds Sionis, Catwoman is making a deal with him, and Batman intervenes. Batman follows Catwoman and finds out Penguin has cryogenic weapons made by Victor Fries. Batman defeats Penguin with ease. Batman beats him and convinces him to leave the criminals alone. Batman goes after Riddler next, who is holding the mayor hostage and beats his games. Two-Face gets his attention by blowing up half of the Gotham Supreme Court. That earns him a face in the ground. Last, Batman goes after Joker, who is trying to recreate his origins. Joker and Batman fight with Harley Quinn getting knocked into the chemical vat. Batman beats Joker and gets Harley out but she’s already insane. Hugo Strange turns out to be behind the breakout and a bomb goes off causing chemicals to gush and flow all the way out into the streets of Gotham. Batman goes to Strange in Arkham Tower and beats him into all of the machinery, and returns to the precinct to let them know that it’s over apart from the rounding up of the criminals.
