Players choose one of six monsters (four in the 16-bit ports) for battle, and two players can join forces to fight the monsters together. Battles end when one of the monsters is pinned for a three count or if time expires (in which case both sides lose). During each round, the player must fight using the punch, kick, or by grabbing their adversary to perform a body slam, pile driver, or an atomic back drop. The game consists of 12 total levels (8 in the 16-bit ports) which takes place in 6 cities in a futuristic 1996
Japan. Each city is featured twice with the game beginning and ending in
Tokyo. Other cities include
Kyoto,
Okayama,
Osaka,
Kobe and
Hiroshima (the latter two are omitted from the SNES port. The Sega Genesis port only features Tokyo with the other cities being "Mega Port", "Dragon City", and "Castle City"). The player first must defeat all six monsters, with the last monster being oneself, but in a different
palette. Then the player must defeat the six monsters again, in the same order, but this time in different cities. ==Characters==
