About This Game

AN ASYLUM AT THE EDGE OF THE KNOWN WORLD

St. Erasmus Sanitarium stands on a remote island. You are its keeper. Every new patient needs help, but the forces beneath the island demand very different offerings. Sanitarium of the Void blends asylum management, island exploration, and a dark story about the cost of every decision.

RUN THE SANITARIUM

Admit and examine patients, choose treatments, and watch their health and sanity. Build and upgrade wards, an operating room, a laboratory, a workshop, and other facilities. Manage your time, money, and materials as new illnesses and events disrupt your plans.

CHOOSE YOUR PATH

Discharge recovered patients for guineas and reputation, or sacrifice them for Dark Favor and forbidden power. Rituals come at a cost to the keeper's sanity. Follow a path of science, cult, or balance through the story and toward different endings.

EXPLORE THE ISLAND AND THE ABYSS

Visit the lighthouse, village, Blackwood, crypt, and shore. Gather rare resources and descend into procedurally generated caves. Fight directly on the map: swing your sword, dodge enemy windups and flying spells, and use consumables to survive.

GROW, CRAFT, RESEARCH

Tend individual garden plots, make medicines, meals, and equipment. Research unlocks recipes and lasting improvements. Summon servants and assign them to tasks around the sanitarium.

Follow a medical investigation from a patient's bedside to clues in Blackwood and a specimen in the caves. Study your finding, craft a remedy, and discover how treatment changes the patient's life after discharge.

Each passing day brings the island closer to another turning point. What will St. Erasmus become under your care?
