Start with the in-game tutorial

The developer recommends playing the tutorial before starting a run. Use it to learn the basic controls and the crafting system before committing to a descent.

The free Steam demo is the current playable starting point. It covers five cave layers, so you can learn the survival systems before the planned full release.

Think about survival before going deeper

Your objective is to retrieve lost cargo from an alien planet. Each layer introduces its own challenges, and the official description rewards caution and patience.

Injuries, infected wounds and blood loss can threaten a run. Learn how dressings and crafting work early, and pay attention to your character’s mood as well as physical injuries.

Learn the systems one at a time

Crafting provides tools for travelling through the caves and supplies for treating wounds. The game also lets you adjust loot and danger settings from the main menu.

The demo includes five layers. The full game is planned to include eleven layers, three characters and three endings; those announced features should not be confused with the demo’s available content.
