The game starts with a maze where the kebiishi and some aliens appear.
The aliens start moving through the maze wherever they please.
While trying to keep from getting eaten, the kebiishi digs holes where the aliens will likely travel.
If an alien comes to a finished hole, it will fall in and be trapped for a while.
While the alien is trapped in the hole, you can fill the hole to bury it.
If all aliens are buried, the round ends and you can proceed to the next round.
The Game Boy version includes both the original arcade version as well as an enhanced version with new graphics and original features such as a super alien that has special powers, moves to avoid holes and chases the keibiishi.
Two players can play via the video link cable.
About Game Boy
The original Game Boy (1989) proved that handheld gaming didn't need cutting-edge graphics to succeed — its monochrome screen and legendary battery life, combined with Tetris as a pack-in, made it a cultural phenomenon. Game Boy cartridges are famously durable, so this remains one of the more accessible retro platforms to collect, though translucent color variants and complete-in-box copies with the original brick-sized manual add real value for condition-focused collectors.
Gamevaro tracks Heiankyo Alien for Game Boy with separate market values for loose, complete-in-box (CIB) and factory-sealed copies, sourced from real eBay sales. Prices also vary by region — PAL, NTSC-U and NTSC-J releases of the same game often sell for different amounts due to print run sizes and regional collector demand.
Adding Heiankyo Alien to a Gamevaro collection takes seconds — search by title or scan the box barcode, and the app fills in cover art, release details and current pricing automatically. This GB release dates back to 1990.
