Join Batman to take down the Joker before he ends the SCU launch party with a bang.
- "Here's the plan. We'll divide forces and meet in the main ballroom where the Joker is holding SCU's top brass hostage. The hotel is swarming with Joker clowns and loaded with Joker toxin. Get through as quickly as you can." — Batman
- Defeat Joker and Save the Hostages
- "Good, I figured you'd get yourself out safely. The Joker's escaped, but it's only a matter of time before we track down his toxin source. When we do, Joker's game is over. For good. I'll be in touch soon. Batman out." — Batman
