Super Hero Operations: Diedal's Ambition

Super Hero Operations: Diedal's Ambition (スーパーヒーロー作戦 ダイダルの野望, Sūpā Hīrō Sakusen: Daidaru no Yabō) is an RPG for the PlayStation that features popular tokusatsu such as Ultraman Gaia and Kamen Rider. It is the only sequel to Super Hero Operations, also for PlayStation.

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 Space Sheriff 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 Japan.
