The Great Battle III

Set in the Compachi Hero universe (which serves as a crossover for the Gundam, Kamen Rider, and Ultraman series), the four heroes Gundam F91, Black RX, Ultraman Great, and Warrior Roa survive their spaceship crashing into a stray asteroid, then find themselves stranded in a forest on an unfamiliar planet. Brought before the king of a local castle, the heroes are assigned a quest to defeat the evil wizard Zanel and his army, before the wizard summons the dormant demon lord Dark Brain.

The Great Battle III is a side-scrolling beat 'em up, in which the player plays as one of four heroes, each with their own fighting abilities. Heroes can be switched throughout the game. The player navigates the hero around the battlefield to beat enemies on-screen, and avoid any stage hazards like pits and falling rocks. Each enemy beaten earns the player collectible gold, which can be used to purchase power-ups in shops.
