This mission, often given by Joker or Circe, involves orchestrating or capitalizing on a breakout at Arkham Asylum in Gotham City. It's one of your first forays into an instanced area.

Objectives:
- Enter Arkham Asylum: Locate the entrance to Arkham Asylum on your map. It will be marked with a mission icon.
- Free Inmates: Inside, you'll encounter Arkham guards and orderlies. Defeat them and interact with cell doors or control panels to release inmates.
- Collect Arkham Files: Find and interact with several filing cabinets or computer terminals to gather sensitive information. Be wary of hero patrols.
- Confront Arkham Security Chief: You'll likely face a mini-boss encounter with a more powerful Arkham security officer or a low-level hero. Utilize your full power rotation and offensive abilities.
- Escape Arkham Asylum: Once your objectives are complete, find the exit.
Reward: Significant experience, cash, and a rare piece of gear (e.g., shoulders or back) with improved stats. This mission also introduces you to instanced content.
