X-Men: Madness in The Murderworld A great side-scrolling arcade game featuring all the X-Men and their cool powers, Madness in Murderworld pits the team against their arch-enemies Arcade and Magneto in Murderworld, the deadly amusement park of terror. The game boasts over 500 action and combat screens, and some puzzle-solving (e.g. find the right key for the door). The game also came with a limited edition comic book that leads up to the action.. and no, I'm not selling mine .
