You are a Corpsec agent dispatched by the Nostos Group to a derelict gone dark. Your orders are simple: Recover the Datacards. Reach the evac. Return with the salvage.

Nostos is a single-player sci-fi survival-horror dungeon crawler played with dice and cards. Think mint-tin game in digital form. Every run drops your salvage crew into a derelict ship crawling with Endoparasites where you'll be stalked by the Matriarch, a terrifying predator that is always right behind you.

Reveal the ship one module at a time; it's a unique layout and a different story each time. Scavenge for grenades, deploy turrets, and make use of medstations. Fight through wave after wave of Endoparasites with a fistful of dice. If you make it to the evac point, the Matriarch corners you for a push-your-luck final stand. Every Endoparasite you fail to kill along the way adds to her HP bar. Bank your hits, or push for more and risk going bust.

Your Agents go from Full Health to Injured to DEAD — and there's no coming back. Endoparasite infection spreads invisibly through the team, costing you dice and, if you don't purge it before evac, possibly denying your survivors a seat home on the dropship. Escape clean or you won't escape at all.

Key Features

• A pocket-sized squad-survival card game. Every run is a tense, self-contained 15-minute adventure — pull it out, play it, put it away. Made to be replayed, not finished.

• Push-your-luck dice combat — the final boss battle is a gamble between banking damage and losing everything by going bust.

• An alien predator that hunts you — the Matriarch closes in each turn; use your items well to reach the evac point with all four members of your Fireteam intact.

• True permadeath roguelike — a freshly shuffled derelict every run, and dead Agents never come back.

• Hidden infection — Endoparasite Embryos spread unseen, sap your dice, and can strip a win at the final bioscan.

• Use your items strategically — grenades, turrets and datacards can modify dice rolls; medstations can patch up injured agents and remove Endoparasite embryo infections; recruit a Survivor to expand your Fireteam, or bring the boss-killing Exo online by recovering all three datacards.

• Multiple endings, four difficulties — from Story to Nightmare, with a legacy game feature called the Contractor that unlocks as you play.

• Atmospheric terminal horror — a cold corporate-salvage future rendered in glowing CRT readouts.

• Fully localized — playable in 8 languages; single-player and offline.

Quick-to-play by design. Nostos started life as a mint-tin tabletop game — a whole experience that fits in your pocket. A single run is about 15 minutes, so it's built to be pulled out on a break and played in one sitting. The depth is in the replay, not the runtime: every run reshuffles the odds, forces new decisions, and tells a different story.

Nostos pays well. Nostos keeps track. Nostos does not pay for bodies left behind. Bring back the Datacards — and as many of your Fireteam as you can.
