In Campaign Mode, the player must win these minigames in order to continue with the main game. The fourth stage is a multiplayer minigame that varies with each time zone, usually as a parody of games such as Asteroids or Breakout. After each city is destroyed, all three monsters are awarded stars for inflicting the most damage on buildings, people, and each other.

Campaign Mode is only playable with one player, but the CPU will randomly select two other monsters to oppose the player in that time zone. The first three consist of traditional Rampage gameplay, in that the player must destroy all the buildings in each city while avoiding attacks from enemy forces. In Campaign Mode, each time zone consists of four stages. Eventually, the monsters are finally defeated. Later, a UFO-like craft is created to stop the monsters, only to fail.

They surprise Scumlabs and enter the time machine, and begin terrorizing the past, present, and future, bringing mayhem to the space-time continuum.

Unfortunately, monsters from the previous games (George the ape, Lizzie the dinosaur, Ralph the wolfman, Boris the rhino, Curtis the rat and Ruby the lobster), have somehow returned to Earth, this time joined by a new monster: Harley the warthog. To speed up the cleaning process, the evil and corrupt Scumlabs creates a time machine to send employees back in time to deal with the destruction without having to do so in the present. The world is yet again rebuilding after the events of Universal Tour.
