A revamp based on the arcade classic Heiankyo Alien, the player must exterminate aliens invading Heiankyo by digging holes that aliens can be trapped in and then burying them before they escape. Once all the aliens are gone the stage is cleared. Two players can play in coop mode as well in the new version. In the new mode the graphics are improved as well as music. The original arcade game mode is included as well.
