Bunker Curves
About Bunker Curves
Bunker Curves is a Ren'Py RPG sandbox from Overflow Studios, presented with 3D CG visuals. It is set in Shelter-09, a bunker deep beneath a post-cataclysmic surface. You play the chief technician, responsible for life support and scavenging ruins while sharing the shelter with Alice, a cynical corporate heiress unprepared for underground survival. Experimental nutritional compounds and radiation scrubbers change her body as you manage daily maintenance, run surface expeditions, assist gym workouts, and oversee irreversible transformations. The game explores a dystopian setting, corruption, and transformation.
The current build is the 0.4-Beta Demo, released on October 20, 2026. It is an initial public demo, so development is ongoing. It runs on Windows, Linux, Mac, and Android, with English text and no censorship. The update adds a complete interactive playthrough covering Stages 0 to 2, along with minigames for scavenging supplies, spotting workouts, and distributing stock. It ends with a cliffhanger that points toward the Stage 3 transformation milestone.
Developer's description
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.
