1512No locks match. Clear the search or change your filters.
The combinations and locations were cross-checked against GamesRadar’s illustrated code guide (external site, opens in a new tab), PowerPyx’s route (external site, opens in a new tab). This is a source-based checklist; we have not entered these codes in the game ourselves.
READ BEFORE THE FIRST LOCK
9901 or 0199?
Both numbers appear in published guides for the red hallway cabinet. PowerPyx’s 8 October comments report 9901 where the original guide had 0199; its guide now includes both. GamesRadar also lists both. We cannot establish whether the difference is build-related, randomized or an earlier reporting error.
Match the portraits and cabinet first. If one reported combination fails, the other is a reasonable next check. Do not assume that reversing every other code is a game mechanic.
The checklist stores “opened,” not “code verified.” Only mark a lock after you have opened it in your own run.
Make the checklist work for your run
- Choose your current section. Avoid looking ahead if you want to limit location spoilers.
- Read the room clue. Similar cabinet names across guides can refer to different locations.
- Check loot before moving on. Keep a manual save when the game lets you, especially before committing to the next area.
- Mark the container only after opening it. The counter tracks your entries; it does not promise an achievement unlock.
Do not mix up the late sewer cabinet with the early sewer ladder progress blocker. If the floor disappears after climbing toward the merchant, use the sewer ladder report guide.
