Vesper Cistern от nhienhoa785

Vesper Cistern is a compact first-person survival game set inside an abandoned night cistern and rain tower. The tower is a single working machine: rain must be collected, dirty water must be filtered, clean water must drive the turbine, and the heat loop must remain stable while charge accumulates for the beacon.

Explore the tower in a ray-cast 3D view, read its physical gauges, and operate each station directly. The challenge is not a pile of unrelated meters. Every resource belongs to one understandable chain, and neglect at one station creates pressure elsewhere. Reach full beacon charge before cold or structural failure ends the watch.
