Project P.I.T.T. Secret Ending Guide — END?, Elevator Code & Route

END? as the Secret Ending — the keypad uses the four digits you discover in your own save (they are save-specific). Short keypad note: the discovery order is Duck → Cash Register → Piñata → Anomaly. For troubleshooting and the broader elevator-code guide, see Elevator Code.

• Collect the four keypad digits in your current save (follow the discovery order: Duck → Cash Register → Piñata → Anomaly).
• When the elevator keypad appears, enter the digits you found in that save.
• Choosing the END? route (secret) or the END! route (main) depends on the in-game choices and which path you take — they are distinct outcomes.

• A playthrough/save that has uncovered the four keypad digits (they are not universal).
• Access to the elevator/keypad event in your save.
• Completion of the associated anomaly phase to obtain the final digit — see Anomaly Phase 4 for details on that step.
• If you care about completion stats or rewards, consult Percentage Pipe and Achievements.

There are two separate endings commonly confused:

• END? is the secret ending — it requires entering the save-specific keypad code assembled from digits you located during that playthrough.
• END! is the main ending and follows a different route; the two are mutually exclusive outcomes based on choices and sequence.

Keypad digits are not a global code printed on a wiki. They are discovered within each save in a fixed discovery sequence: Duck, then Cash Register, then Piñata, then the Anomaly (the latter ties to the anomaly phase). Once you have those four digits in your save, input them on the elevator keypad when prompted to trigger the secret route.

Do not expect a single universal number to work across all saves. Threads and storefront pages sometimes show a specific sequence (or a single-string code), which reflects a particular save — that is why players see conflicting reports like “Lost on ending.” If the code you try fails, consult Elevator Code for troubleshooting steps that respect save-specific fixes rather than blanket codes.

• Treating a single posted code as universal — codes are save-specific.
• Entering digits in the wrong order (use your discovered order).
• Skipping the Anomaly phase or misunderstanding where the final digit appears — refer to Anomaly Phase 4.
• Using sites or comments that post fixed numbers without clarifying save dependence.

• Re-scan your current save for the four digit sources in the order above.
• If you can’t get the keypad to accept your discovered digits, check the troubleshooting steps at Elevator Code and Troubleshooting.
• Track completion and rewards via Percentage Pipe and Achievements.

There is no single universal keypad code. The keypad code for END? is built from four digits you find in your own save (Duck → Cash Register → Piñata → Anomaly). Do not rely on codes copied from other players’ saves.

Find each digit during your playthrough in the four locations listed above, then enter them on the elevator keypad in that same save. If you’re stuck on locating the final digit or the anomaly step, see Anomaly Phase 4 and the general Elevator Code troubleshooting guide.

If you tried “2640” (or any single posted number) and it failed, that’s because keypad codes are save-specific; a number that worked in one save will often fail in another. For troubleshooting and steps that respect save-specific fixes, use Elevator Code and Troubleshooting.

END? is the secret ending triggered by entering the save-specific keypad code and following that route. END! is the main ending achieved through the standard progression. They are different outcomes and should not be conflated.
