About Fishing The Abyss - Aquarium - DLC

Fishing The Abyss - Aquarium - DLC - about the game
Dive into your catches from Fishing The Abyss with this free aquarium expansion. Place creatures into a spacious tank, mix and match them freely, and watch them swim in a wide 16:9 view. Run it alongside the main game or solo after heavy playtime-launch via the library menu or manually from the dlc_aquarium folder for dual operation on PC. Measure creature sizes to chase record hauls, inspect their full bodies up close, and feed them to spur massive growth. This casual indie setup lets you observe and nurture abyss dwellers in relaxing detail. Perfect for laid-back players who savor post-fishing downtime.

*This downloadable content is designed to be played in conjunction with the save data from the main game, Fishing The Abyss.

A free downloadable content that slightly expands the world of Fishing The Abyss

Unlike the vertically long window of the main game, this content is played in a 16:9 horizontal window.

You can run both the main game and this content simultaneously, or if you've already played a lot of the main game, you can also run this content on its own.

How to Launch the DLC

In your Library, click the "Play" button on the main application "Fishing The Abyss." A launch options menu will appear—please select "Fishing_The_Abyss_Aquarium" from there.

How to Launch Both the Main Game and DLC Together

If you launch the game using the standard launch options, you can only start either the main game or the DLC, not both at the same time.

To run both the main game and the DLC simultaneously:

・Right-click on the main game title in your Library

・Select “Browse local files”

・Open the “dlc_aquarium” folder in the window that appears

・Run “Fishing_The_Abyss_Aquarium.exe” manually from inside the “dlc_aquarium” folder

With this method, you can launch both the main game and the DLC at the same time.

・View the creatures you caught in a large aquarium

Place the creatures you caught in the main game into the tank in any combination you like and enjoy watching them!

・Measure the size of creatures

Measure the size of the creatures you caught in the main game and aim for the biggest catch!

・Observe the full body of each creature

You can now fully observe the enormous creatures that couldn’t be entirely seen in the vertically long window of the main game!

・Feed them to increase their size

You can feed the creatures to make them grow, allowing you to raise them to sizes you've never seen before.
