Five layers in the free demo
The official Steam demo contains five of the game’s planned eleven layers. Each layer brings its own survival challenges and hazards.
Use the demo to learn exploration, crafting and the injury systems. It is a separate release from the full game.
Eleven layers planned for the full game
The developer’s launch announcement lists layers six through eleven as part of the full release, alongside three characters, three endings and forty achievements.
The September progress update describes ten main layers, a shorter eleventh layer and an optional bonus ending sequence. These are announced plans, not a claim that every area is present in the demo.
Prepare before each descent
Tools help you travel through the caves; dressings and other survival supplies help you manage injuries. Caution and patience are rewarded.
As of the November 8, 2026 research check, the full release is planned for November 9. The developer says the demo will not receive the full game’s launch changes.
