"Rampage is a 1986 arcade game by Bally Midway. Players take control of gigantic monsters trying to survive against onslaughts of military forces. Each round is completed when a particular city is completely reduced to rubble.
Up to three simultaneous players control the monsters George (a King Kong-like gorilla), Lizzy (a Godzilla-like dinosaur/lizard), or Ralph (a giant werewolf), created from mutated humans. They need to raze all buildings in a high-rise city to advance to the next, eating people and destroying helicopters, tanks, taxis, police cars, boats, and trolleys along the way.

Monsters can jump and climb buildings, and punch enemies and buildings. Buildings also take damage when jumped on by a monster.

The player receives damage from enemy bullets, grenades, shells and so forth, and from falls. Damage is recovered by eating appropriate food such as fruit, roast chicken, or soldiers. If a monster takes too much damage, it reverts back into a naked human and starts walking off the screen sideways, covering its genitals with its hands. While in this state, the player can be eaten by another player. If the player continues, the human mutates back into the monster, or flies in on a blimp if off-screen, with a full life bar."
