Heiankyo Alien — About this game
Heiankyo Alien turns a maze into a set of traps rather than a shooting gallery. Dig a hole in an alien’s path, lure it in and fill the pit before it climbs out. Old and New game choices change the presentation and challenges, while linked play offers ways to share the hunt or compete with another defender.
