Bunker Curves [v0.4-Beta Demo] [Overflow Studios]

October 24, 2026F95

Deep beneath the post-cataclysmic surface lies Shelter-09. You take on the role of the bunker’s chief technician, responsible for keeping life support running and scavenging surface ruins. Trapped alongside you is Alice — a sharp-tongued, cynical corporate heiress completely unsuited for subterranean survival.

As experimental nutritional compounds and radiation scrubbers alter her physiology, manage daily bunker maintenance, run surface expeditions, assist in intensive gym workouts, and oversee dramatic, irreversible bodily transformations.
