Samurai Aces

Sengoku Ace (Sengoku Ace (戦国エース)), fully titled Sengoku Ace: Tengai Episode I and also known as Samurai Aces in the English version, is a vertically scrolling shooter released in the arcades by Psikyo in 1993. The first game by Psikyo, Sengoku Ace was designed by Shinsuke Nakamura, the creator of Aero Fighters (Sonic Wings) and the company's founder.

Plot
The science fantasy story of Sengoku Ace resolves around the six Feudal Japan (Sengoku period) characters sent on a mission to stop an evil cult and rescue the Shogun's kidnapped daughter, princess Tsukihime (Moon Princess), before she can be used as a sacrifice to resurrect their demon god. The game features 21 endings, different for various characters and two-player pairings.
