Galaxy Deka Gayvan is a brawler. Players can choose to control either of the two heroes, or both of them in a co-op mode. Like in other beat-em-up games, the player must defeat all the enemies on screen in hand-to-hand combat before being able to proceed. Both Hiro and Michiko can accumulate special energy (dropped by the enemies along with health power-ups and money) that allows them to transfer into the superheroes Gayvan and Mittchi and stay in that form until they run out of energy. The superhero forms are stronger and are able to execute special attacks. In addition, a two-player versus fighting mode is included. Players can choose either the protagonists or three enemy characters to compete against each other in one-on-one fighting. Less
