A downloadable game


Welcome aboard the Nauti Buoy, our research facility's latest state of the art submarine;  capable of diving down deep waters and destroying anything that gets in the way.

Recently, our scientists have discovered some underwater ruins overrun by gigantic and dangerous sea creatures.

Your latest mission as the captain piloting this new vessel would be to traverse deep underwater and clear the site so it may be suitable for research.

We wish you and your crew a safe return!

Nauti Buoy is a classic retro 8-bit top-down shooter game, capable of being played on the original 1989 Nintendo Game Boy.

Install instructions

Playing on an Emulator
You can play the game on an emulator. We reccommend Emulicious as it is cross-platform.

Playing on a Game Boy
You can also play the game on an actual Nintendo Game Boy by downloading the game into a flashcart.

Nauti Buoy comes in either Japanese or English! Just download the language you prefer to play in! As we translated the game into Japanese by ourselves without a professional, we apologise for the poor translation.

このゲームはエミュレーターでできる。クロスプラットフォームの Emulicious をお勧め。

Nauti Buoy は英語版も、日本語版もあり、お好みのバージョンをダウンロードして下さい。プロではなく、自分でゲームを日本語に翻訳したものですから、下手な翻訳で申し訳ございません。
