An assault unit lands on a low-gravity refinery moon to secure central control and investigate a biological contamination. Inside the complex, the system begins absorbing workers into its structure, forming a living network that controls the station.

The deeper they move, the more the station stops behaving like a place and starts reacting like something aware.

Comms fail, corridors change, and the structure itself turns into the threat while time and oxygen begin to run out.

What looked like containment becomes something else...
