Galaxy Deka Gayvan — About this game
Hiro and Michiko fight criminal forces in a scrolling brawler where collected energy lets them transform into stronger superhero forms. Enemies drop useful resources, so clearing a group can prepare the heroes for a more dangerous encounter ahead. Watch both sides of the screen, keep opponents from surrounding the active character and use the limited transformation energy when its additional power can make a difference. The superhero presentation changes the fighters' attacks as well as their appearance. A separate versus mode turns the cast into one-on-one opponents, while the main adventure follows the cooperative rescue-and-combat journey.
