Ultraman Great is the ultimate warrior and protector of peace in the entire universe. For eons he’s been fighting an intergalactic battle against Gudis, an evil virus that attempts to wipe out all competing life forms. Now the Gudis virus has infected Earth, producing a horrifying group of giant mutant monsters to carry out its goal of the complete obliteration of every organism on Planet Earth.
Ultraman must now battle Gudis and his mutant monsters on Earth. But the Earth’s polluted atmosphere poses a threat to Ultraman and he has to become part of a human’s molecular structure. Jack Shindo has the ability to transform into Ultraman Great by using his Delta Plasma Pendant (which holds Ultraman within his molecular profile) to transfer his molecules into that of the interstellar hero.
Cast in the role of the titular Ultraman, Ultraman Great, the player must defeat many of the same monsters that appeared in the original series. As a one-on-one fighting game, Ultraman can punch, kick, and grapple his opponent, in addition to using a variety of various special moves that must be charged.
However, in order to actually defeat his opponent, Ultraman must deplete their continually-recharging life bar, and at that moment hit them with the Burning Plasma (which is his most powerful attack). As the game continues, different enemies may develop ways to evade the final blow. Ultraman must adapt to their changing ways.
