About this game

Abyssonaut - is a survival exploration game with base building and resource management elements, where you play as the last surviving employee of a laboratory that was studying a mysterious abyss.

Lore

You are one of the last surviving members of a laboratory that discovered the abyss and began to investigate it.

After several expeditions, the laboratory was heavily damaged, and the path back was sealed. During their research, the team discovered the first unidentified entity, which they named the <Appraiser>.

The Appraiser accepts various items retrieved from the abyss:

  • resources

  • artifacts

  • relics

By evaluating their value and consuming them, it can create anything that is already known. An item becomes known only after its formula has been discovered.

The team had no choice but to descend deeper into the abyss to gather more value and repair the laboratory.

And you… were left behind.

Explore, Gather, and Survive

There are two main ways to craft items:

  • Crafting using laboratory equipment

(Laboratory equipment requires maintenance and resources)

  • Crafting using the Appraiser

Both methods require the crafted item to be known.

Power and Life Support
