The add-on chronicles Lo Wang's adventures after the original game. He visits his relatives in USA, but is forced to fight off Zilla's forces again. The game culminates with a battle against Master Zilla above the streets of Tokyo, which ends with Master Zilla's death. The game features 12 new levels, new artwork and a couple new enemy replacements, such as human enemies; though they still act as their original counterparts. (wikipedia)
