It may have mutated into a questionable Dwayne Johnson movie, but Rampage started as an '80s arcade hit, centered around three erstwhile scientists who tear their way across the country after transforming into giant monsters. Players choose a character and then must destroy all the buildings on a level to advance, eating people and other food for health and avoiding attacking helicopters and soldiers. Like the arcade version, the MAME version ties the character to the controls, so you may need to edit the controls in the Tab menu to get the character you want. Rampage's pixelated cityscapes, tiny denizens, expressive creatures and addictive gameplay make it a classic worth playing today. It also spawned a sequel, Rampage World Tour, over a decade later.
