The free Steam demo contains five of the full game’s eleven layers, with the current mechanics available in those playable areas. Each layer presents its own challenges. The official sources do not provide a stable, complete hazard list for every layer, so this guide avoids invented routes and enemy placements.
Prepare at every transition
- Before descending, inspect wounds, bleeding, supplies, and your ability to recover.
- Keep useful crafting materials and medical resources; do not fill every slot with speculative loot.
- Enter an unfamiliar area slowly. Learn its hazards before committing to a route.
- After a near miss, reassess. A minor injury can snowball when the next layer is more hostile.
Demo versus full game
The demo gives access to five layers. The official Steam demo description says the full game has eleven. Treat footage or guides from later areas as full-game material; they may describe content you cannot reach in the demo. Start with the beginner guide if you are learning the survival systems.
Official descriptions: Steam demo and Orsoniks on itch.io. Where this page gives a recommended order, it is a general survival strategy, not an official rule or verified item recipe.
