Joker's Celebration: 15 Years in Arkham

Batsy, darling! 15 years of our dance in Arkham's halls! Come, let's celebrate with a bang! I've "borrowed" some G-Bucks from our dear city. Want them? Then play my game! Answer the signal, face my challenges, crack the egghead's puzzles, and outfox the bird-brain. It'll be a killer party!
