This game allows one to eight players to control separate tanks (either as teammates or as opponents). The player(s) can play either in the heart of downtown Tokyo or at the city's bayside dock. However, the players have twenty seconds to make all the decisions before the game automatically locks them in. The tanks are identical except in color; green (representing the Green Godzillas) and white (representing the White Mammoth). The storyline provided by the game's promotional poster states that the game takes place in the 1990s.
