Secret Ending

The hidden path runs through the Fuses, 200 KG platform, Percentage Pipe, IGTAP, Mining, UV Light, Keycard, and elevator Keypad. The route is clear; the exact code and END? / END! labels still conflict.

Spoiler-light answer

Finish the upper-facility puzzle chain before taking the obvious ending. The community route is: three Fuses → 200 KG platform → Percentage Pipe → IGTAP → Mining → UV Light → Keycard → elevator Keypad.

Spoiler boundary

The next section names the puzzle sequence and final interaction structure. Stop here if you only wanted confirmation that a secret ending exists.

Community result: complete route

  1. Disable or destroy the surveillance cameras, then collect and install all three Fuses.
  2. Load the upstairs platform to 200 KG or more.
  3. Feed Anomalies into the Percentage Pipe until it reaches 100% and opens the next route. Guides disagree on whether this takes about two Anomalies or ten.
  4. Complete the IGTAP parkour minigame.
  5. Complete Mining to obtain the UV Light.
  6. Put the Pickaxe into the Anomaly Crafter to make a Keycard.
  7. Use the Keycard to reveal the elevator Keypad.
  8. Use the UV Light to find four digits near the manual Duck, Cash Register, Piñata, and Anomaly machines; read them in that order.
  9. Enter the code from your own save and take the elevator route before committing to the ordinary ending.

Community results conflict on the code

One guide publishes 2640, another recorded route shows 6827, and two detailed routes say the four digits are generated per save. The safest method is to read the UV digits in your own game instead of copying either fixed number.

About SECRET?, END?, and END!

Steam keeps the descriptions for these achievements hidden. Community guides currently conflict over whether END? or END! labels the secret route. Because the punctuation is easy to transpose and Steam does not expose the descriptions, do not rely on either third-party mapping until the unlock notification is recorded.

Community results conflict on the ending labels

Whisper and the Field Manual map END? to the Secret Ending and END! to the Main Ending. NineWiki maps END? to the first stats/internship ending and END! to the later second ending. Keep both labels unresolved until the unlock notification is recorded beside each ending.

Final report UI

The end sequence closes with a black-and-green PERSONNEL FILE / FINAL INTAKE REPORT screen showing run statistics, then offers RETURN TO MAIN MENU and TERMINATE SESSION. Record the Steam unlock notification or timestamp before leaving this screen if you are testing the END? / END! mapping.

If the keypad route does not open

  • Confirm every prerequisite puzzle has actually resolved, not merely been visited.
  • Check for a missed fuse, gate, or minigame result in the late-game spaces.
  • Do not trust a demo-era guide for the release build.
  • If a copied code fails, return to the four manual machines and read the UV digits from your own save.

Secret ending FAQ

Is there one keypad code that works for every save?

No reliable universal code has been confirmed. Published runs show 2640 and 6827, while detailed routes report save-specific digits. Read the four UV digits in your own game.

Where are the four UV digits?

Check near the manual Duck, Cash Register, Piñata, and Anomaly machines, then enter the digits in that order.

How many Anomalies does the Percentage Pipe need?

Community reports conflict between roughly two and ten. Stop counting and watch the pipe: keep feeding it until the display reaches 100%.

Is END? or END! the secret ending achievement?

Still unconfirmed. Steam hides both descriptions and current guides swap the labels. Use the route, then note the exact Steam unlock notification instead of choosing an ending by punctuation.
