Phagocytosis

Phagocytosis; The process by which a living organism's immune cells absorb and kill antigens—external threats.

A self replicating space craft (Von Neumann probe) threatens all matter in a single system. If not dealt with, it will replicate ad-infinitum until every last speck of material is itself part of a probe.

The only way to kill it: get inside and destroy its brain. The only problem? That brain is thinking, learning, and trying to kill you at every turn.

Phagocytosis is a system-agnostic sci-fi adventure module designed to be played in a single session. Inspired by the likes of Factorio, Universal Paperclips, Mass Effect, and Alien.
