The 15-minute loop
Sheriff James Cooper wakes in Saint Heritage Hospital with a wound that will kill him in about fifteen minutes. Death restarts the loop, and the official description says he carries memories into the next attempt. That is the central answer to how this walkthrough works: learn from a run, then use that knowledge when the clock starts again. The source material does not justify a guaranteed minute-by-minute route through every room.
Two independent full-game videos label chapters one through nine, and the achievement catalogue also names chapter goals through chapter nine. That supports a nine-chapter navigation outline for the full release. The videos do not provide a checked written step list for every objective, and their runtimes should not be mistaken for a typical first playthrough. Use their chapter markers to locate a scene, not as proof of every hidden item or route.
What carries into the next run
The official Steam description confirms that Cooper retains memories, gains experience and can tailor abilities to his playstyle. It also describes branching dialogue that reacts to early choices. The store does not publish a full inventory-persistence table, so do not assume that every item survives a reset. Specific item-by-item carryover rules are 待确认 in this research.
The story presents each failed attempt as useful because Cooper remembers what happened. That is different from a confirmed promise that weapons, ammunition or keys remain in inventory. If a guide claims a precise carryover rule, check that it refers to the same game version and has in-game support. The research cannot turn the broad official progression description into a detailed save-system chart.
Explore the hospital
The game encourages returns to areas that were previously inaccessible. Search Saint Heritage Hospital for clues and revisit blocked routes as the official ability system develops. The store also names Cooper’s deputy, Rose Watters, as a key person in the story. It does not supply a verified order for every locked floor or room.
Developer answers identify several discrete obstacles across the hospital. A first-floor Locker Room clue for the full game lies in basement Medical Storage, while another response directs a player with a computer puzzle to numbers on the wall beside the machine. These are location-specific hints, not a complete map of connecting corridors. The map guide keeps confirmed room names separate from missing floor-plan details.
When you get stuck
The developer’s progression thread includes targeted hints. For a chapter-three Blood Exchange Station interaction, the developer says to hold the input instead of tapping it. Other replies address chapter-two kitchen access and later puzzle rooms. The thread is organized around player questions rather than a complete chapter-by-chapter route.
The research also found a developer hint for the chapter-seven Anger fight involving mines and red barrels. Its exact combat sequence was not independently checked frame by frame, so a guaranteed tactic is 待确认. A separate page covers the chapter-nine final boss with the patch history that affects that fight. Do not transfer a hint from one chapter to another simply because both involve combat.
Version notes
The free Prologue is a separate Steam product, so its old locker instructions are not automatically valid for the full game. The official 1.1.0 update says saving with a regular, non-red film reel after choosing a door no longer permanently locks that choice. You can reload that save and choose the other door according to the patch note. Earlier developer comments describing an irreversible choice are Legacy / Old Version information.
Later official notes also adjust boss phases, puzzle interactions and the first pouch upgrade location. A pre-patch video can be a genuine record of its day while still failing as a current route. When a step disagrees with your build, check the publication date and the developer’s update history before assuming you missed a clue. The research did not find a current, independently verified written walkthrough for every chapter, so full step-by-step coverage remains 待确认.
