Metal Mutant

Metal Mutant is an action game, where you control the eponymous machine, sent to the planet Kronox to find and destroy the insane computer AROD 7. Each level is not side-scrolling fluidly, but is divided into separate screens; upon getting to the edge of one screen you move to the next one. The Metal Mutant has the ability to transform into 3 different forms: humanoid, dinosaur and tank. (mobygames.com)
