About Samurai Ace

Sai-Kyo's commemorative first title.

Its simple controls and unexpected world setting sparked discussion, earning it the 1993 “Best Shooting Game Award” from several industry magazines.

Touhou Sengoku Kitan

A tale from the distant past, at the eastern edge of the world.

There, a vibrant town culture, advanced technology, and ancient sorcery coexisted without contradiction, maintaining a long era of peace.

But then, the heretical cult “Shinrakyo” plotted to overthrow the world by resurrecting an evil god, kidnapping Tsukihime, the daughter of the Shogun, as their sacrifice!

Six ace pilots, each harboring their own resolve, gather.

Now, an astonishing aerial battle begins!

● 8-direction lever + 2-button controls.

● 8 stages total.

● Supports 2-player simultaneous play and mid-game join.

● Charge shots with the shot button to unleash special attacks.
