What the map can confirm
No complete, downloadable official map of Saint Heritage Hospital was found in the collected sources. The Steam description establishes the hospital as the principal setting and says previously inaccessible areas can be revisited. Developer replies name specific floors and rooms, but they do not provide a coordinate-complete floor plan. This page is therefore a verified room-and-route index, not a drawn map pretending to cover every corridor.
Known floors and room names
Players in the developer discussion refer to first, second and third floors and a basement. Developer answers use names including Medical Storage and Examination Room in response to those requests. Those references confirm that clues and objectives span multiple levels, but they do not fix every room’s position relative to elevators or stairs. Exact room-to-room paths for the current build are 待确认.
A verified basement clue
The developer specifically directs players seeking the full-game first-floor Locker Room clue to basement medical storage. That is the most concrete route fact in the collected map material. It identifies the clue’s destination floor and room name, but not a full path through every intervening door. The free Prologue has its own first-floor locker answer, so a map note from one product should not be assumed identical in the other.
How backtracking works
The official feature list says players return to areas that were previously inaccessible to obtain abilities and valuable items. A review author reports that the in-game map marks visited, locked and cleared rooms, but the precise interface behavior has only that one independent account. Mark that map-display detail 待确认 until it is observed in a current game capture. The confirmed practical point is that revisiting old areas is part of intended progression.
Missing map details
No verified high-resolution floor image, complete key list or current-version coordinate chart was available. An official patch moved the first pouch upgrade closer in version 1.1.1, so even a once-accurate old route can become stale. Do not infer a chest, key or shortcut location from an unlabeled video description. Use the puzzle index for verified clues while the full map remains 待确认.
