Death in Space

The universe itself feels tired and hostile; survival means keeping your crew together and the lights on. The system runs lean, in the OSR/NSR spirit.

Theme and Setting

You make quick tests when outcomes are risky and let the fiction lead otherwise. Characters are classless and fast to build; gear, ship modules, and scars do the heavy lifting.

How Play Feels

Combat is brief and brutal—cover, positioning, and whether to engage at all matter more than granular tactics. Procedures emphasize exploration pressure (time, light, fuel, air) and rulings over rules, so scenes move quickly and consequences bite.
