Key facts (sources on each linked page):
- US$22.99 base price (check Steam for current discounts). Windows only on Steam. Steam Deck rated Playable. No controller support in-game. Single-player; multiplayer only through a fan mod.
- 11 layers: Gravel lands, Deeper gravel lands, Dried desert, Wasteland, Overgrown depths, Frozen chasm, Fungal pools, Crystalline hollow, Geothermal vents, WHERE WE MUST REACH, CRIMSON ASCENT. A bonus lab sequence follows for some endings.
- 3 characters: Experiment (STR 9, RES 8, INT 7), Milky (unlocked by finishing a run as the Experiment; INT 16), Dune (unlocked by finishing a run as Milky; STR 16, RES 16, INT 0).
- 3 endings, all triggered from the top of layer 11: bio-pod, escape, M.E.R.C. Dying ends the run.
- Saving only happens between layers. The console command saveandquit saves mid-layer but disables achievements. Open the console with the backtick/tilde key.
- Hemothorax: stop internal bleeding (L.R.D., procoagulant or helluce), then use a chest drain (-35 per use).
- Dislocation: use "Fix dislocation" with a wrench (INT 12 to craft). Bare-handed pushes hurt and can fracture the limb.
- Intelligence rises from first-time crafts, reading E-PDAs (35 XP) and blueprints (25 XP), haggling, buying and reaching new layers.
