After a nearly 10-year hiatus, the cult classic first-person shooter game is back, this time for Windows and Linux, as well as Macs; and it’s available for free download. You’ll find yourself a decade from now and The Walt Disney Company has purchased Florida. Your job is to infiltrate the Magic Kingdom, blasting your way through animatronic pirates, holographic ghosts, clowns, kids, camera-toting tourists, security guards; and even Mickey, Donald, and Goofy. Your objective, seek and destroy the frozen head of Walt Disney and stop Michael Eisner’s doomsday device. For the game averse there’s always downloadable screensavers, artwork, and souvenirs available.
