The Joker
Gotham City’s most heinous Super-Villains have descended upon the city, all determined to rule the metropolis once and for all. Most of them are in it to corrupt the city and gain points, while The Joker sends Gotham City further and further into anarchy with each passing round, slightly altering the way the game is played.
You are secretly one of these Super-Villains, filling character wallets with Corruption Cards worth positive or negative corruption points. Throughout the game, players can eliminate wallets from the game, sending the caught Super-Villain to Arkham Asylum. Each round, The Joker will cause anarchy and change the rules for the next round! At the end of the 7 round game, everyone will score bonuses for any players they eliminated, and, if not eliminated themselves, will reveal their Super-Villain identity and add any corruption points contained in their Super-Villain’s wallet.
