Scope and Evidence

Editorial review: October 8, 2026. This guide covers the Part I four-key escape described in September gameplay sources. The official experience listing now includes Part 2, but we have not checked fresh Part 2 gameplay. The official description still states a four-key and one-code objective. The scene image is official promotional media, not a verified key-spawn screenshot.

Four-Key Search Checklist

Use this checklist alongside a Part I walkthrough. It is a search method based on the reviewed sources, not a map of four guaranteed spawn locations.

  • Identify the elevator lobby, four-lock panel, keypad, and return route before starting a sweep.
  • Clear one connected corridor section at a time and inspect its interactable dressers and drawers.
  • Look for the Take Key prompt and complete the pickup interaction when a key is visible.
  • Leave searched drawers open as a visual marker where the current session allows it.
  • Return to the elevator panel when the route is safe, insert recovered keys, and check the green indicators.
  • After four indicators are green, check the separate keypad requirement before attempting the exit.

Where to Look for Keys

September walkthroughs show players searching downstairs dressers and drawers. The reviewed sources do not establish four permanent named key rooms or a complete spawn table. Follow the furniture-search route in your session instead of treating a room name from another run as a guaranteed location.

A visible Take Key prompt is a useful pickup cue. If it does not appear, check the container and interaction position before deciding the drawer is empty. A missing prompt alone does not prove that the container has no key.

Track Searched Rooms and Installed Keys

Choose one adjacent branch, check its furniture, and preserve the route back to the stairs. Open drawers can help distinguish searched furniture, but they are a route aid rather than a guaranteed persistent record across resets or updates.

At the elevator, count green indicators after each insertion. The reviewed sources describe one green indicator per installed key. Use the panel state to distinguish installed keys from keys you may still be carrying.

Missing the Fourth Key

If fewer than four indicators are green, first check whether you are carrying an uninstalled key. Then return to the last unchecked branch, inspect missed furniture, and use your route markers to avoid repeating the same loop.

The official description does not guarantee how carried or installed keys behave after every death, reset, or update. Recheck the actual panel state after an interruption. Returning keys promptly is a navigation recommendation, not a promise that it banks progress through every reset.

Four Keys but No Exit

Four keys satisfy only the key requirement. The official objective also requires one code. Compare your keypad entry with the clue in the same run, then check the elevator interaction in your current build.

For a video description or community resource list, describe this page as a Part I four-key search checklist. It should not be cited as a current Part 2 map or evidence for fixed key coordinates.
