Rampage World Tour is a video game released in 1997 and is the second game in the Rampage series.
Up to three simultaneous players control the monsters George, a King Kong-like gorilla, Lizzie, a Godzilla-like dinosaur/lizard, or Ralph, a giant werewolf, created from humans who were mutated by experiments conducted at Scum Labs. They need to destroy all buildings in a high-rise city to advance to the next city. On their way they can destroy helicopters, tanks, taxis, police cars, boats, and trolleys, as well as eat people.

The monsters can jump and climb buildings, and attack enemies and buildings with punches. Some buildings also take damage when jumped on.

The player receives damage from enemy bullets, grenades, shells, etc., or from falls. Damage can be recovered by eating the right 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 themselves with their hands. If the player continues, the human will mutate back into the monster with a full life bar.

The game was originally released as an arcade game and was then ported to the Sega Saturn, Nintendo 64, Game Boy Color, PlayStation, Microsoft Windows and as a download on the Playstation 3's Playstation Network. It has also been re-released on Midway Arcade Treasures 2, as well as being an unlockable in Rampage: Total Destruction.
