At‑a‑glance: OSR/Black Hack lineage • d20 tests with Advantage/Disadvantage • 3–5 + GM • Low prep • Rules‑lite • 2–3h sessions
Futuristic bug hunts, derelict ships, and corporate black ops. You play hardened marines facing overwhelming threats with limited gear and no backup.
Simple d20 tests with Advantage/Disadvantage, escalating tension clocks, and resource pressure on ammo and wounds. Character creation is fast and classless with specialty gear.
Combines OSR lethality with mission‑driven objectives and panic‑inducing attrition. Emphasizes team positioning, suppressive fire, and evac timing over build math.
Perfect for Alien‑style survival and 80s military‑sci‑fi action. Great for convention slots, pick‑up nights, and groups who want fast resolution and high stakes.
A fast OSR one-shot game of space marines under pressure. Reviews highlight quick prep, punchy Black Hack–style rules, and a tense ammo-and-stress loop; common caveats: it is lethal by design and tuned for missions over campaigns.
Compare Stay Frosty with other great ttrpg games.
Shares lethal sci‑fi survival and stress management; Stay Frosty is lighter and faster for one‑shots, while Mothership supports longer campaigns and deeper subsystems.
Both deliver grimy space survival with failing tech; Death in Space leans toward scavenging and cosmic dread, Stay Frosty toward military missions and fireteam tactics.
Alien offers cinematic stress dice and franchise horror; Stay Frosty strips it to OSR bones for speed, trading branded depth for quick setup and immediate action.
