About This Game

〈ARTDINK GAME LOG Series〉

ARTDINK GAME LOG is a project to port and re-release game titles previously developed by ARTDINK onto modern gaming hardware.

It serves as a record (log) of ARTDINK's game development journey. By reviving past masterpieces using current technology and platforms, it delivers nostalgia and rediscovery to longtime fans, while offering an unprecedented experience to new players.

〈Curiosity takes a stroll by the sea〉

“Aquanaut's Holiday” is a simple 3D adventure game in which you explore a mysterious underwater world aboard a submarine. Released for the PlayStation™ in 1995, the game has no specific objectives to achieve. It can be considered a pioneer of free-roaming games designed simply to let players enjoy the environment.

〈What you've been looking for is right here〉

You are an employee of the International Oceanographic Research Institute.
Having taken a vacation to rest your weary mind and body,
you set off on an underwater adventure aboard the state-of-the-art submarine “Holiday,” entrusted to you by your superior.

What you discover in the vast ocean is entirely up to you.
You can swim around without a care in the world, interact with the fish, or discover ancient ruins and let your imagination wander to civilizations of the past.

The underwater world is full of freedom and adventure.
Take on the challenge of mapping your assigned waters, and you’ll encounter familiar, adorable fish and strange creatures wherever you go.

Don’t forget to stack blocks to build artificial reefs.
As your artificial reefs grow, more marine life will visit the area.

Here, you’re sure to find a sense of peace you won’t find on the ground.
Relax and enjoy your holiday, letting your curiosity lead the way.

〈Scenes from the past come vividly to life〉

ARTDINK GAME LOG has added a “Remaster Mode.”
The textures of the aquatic creatures have been upgraded to high resolution, allowing you to admire their patterns and expressions in detail.

Of course, it also features a “Classic Mode” that lets you enjoy the game just as it was back then.
What’s more, by using screen filters like ‘Scanline’ and “CRT,” you can immerse yourself in the atmosphere of “those days” when you used to play.

The package also includes the original manual from that era, which explains the background story and how to enjoy the game.
Why not return once more to the beautiful underwater world that captivated you back then?
