Players assume the role of Gamu Takayama, a member of the fighting force XIG, as he combats evil creatures with the power of Ultraman Gaia. Along the way, he meets other heroes, such as Uchuu Keiji Gavan, Seiun Kamen Machineman, and Kikaider. The battle system of Super Hero Sakusen: Diedal's Ambition is turn-based; characters take turn inputting and executing commands. Neither of these two games were ever released outside of Japan.
