Dr. Muto

2002, developed by Midway Games

Dr. Muto is a fully 3D, free-roaming, third-person action adventure game set in a stylized universe full of fiendish puzzles, mind-bending devices, freakish monstrosities, and twisted comedy. You are Dr. Muto, a maniacal and genius mad scientist whose latest experiment has accidentally destroyed his own home planet--all except for his laboratory. The game features a cast of unusual characters including Dr. Muto's sidekick, Janky, and his nemesis, Professor Burnital. By simply sampling some DNA, the doctor can morph into a spider, mouse, gorilla, or whatever creature he sees fit to become. Now he must use his fiendish gadgets and morphing ability to steal organic matter from the neighboring planets in order to rebuild his world.
