Heiankyo Alien

Heiankyo Alien is a compilation of the original arcade game and three arranged versions.

Arcade version

This is a port of the original arcade version, which was a hit in 1980.

Heiankyo Alien 3671

This arranged version shifts the focus from defending to attacking. It is a five-minute score attack with infinite lives until time runs out. Items you dig up can extend the timer by up to 90 seconds.

Kill a certain number of aliens to earn items that give you advantages. A buried diamond doubles your score, and recovering all buried items earns a special bonus. The game features psychedelic graphics, explosive score growth and effects that reflect the game’s development. Its music is composed by Wing☆ and Ibojima, a Swedish Techno/Trance unit.

Glitch Encore Alien

This version includes a scoring bug from the TK-80BS version that was absent from the arcade game because of hardware limitations. The bug was fixed in Heiankyo Alien 3671, but is retained here as a feature because it affects scoring without causing other negative effects.

Idle version

Made in collaboration with Guildoll, a group described as “2.5 dimension figure idols who want to be loved,” this version sets a goal at each level. Each member has a different scenario, and the gameplay is arranged differently from Heiankyo Alien 3671.
