To access the Museum or Developer Commentary content in The Stanley Parable Ultra Deluxe, you must first unlock the special Bucket Museum Ending by entering a specific keypad code in the boss’s office. Here’s a detailed step-by-step guide to help you reach the museum:

Step-by-Step Instructions

1. Locate the Boss’s Office
Start by heading to the boss’s office, which you can find by going through the left door in the two doors room and proceeding upstairs.

2. Input the Keypad Code
Once inside the boss’s office, locate the keypad and enter the following code: 2-8-4-5. This will trigger a mechanism that opens a hidden passage.

3. Access the Secret Passage
After entering the code, look near the fireplace; a secret passage will appear. Walk through this passage to begin your journey into the hidden area.

4. Take the Left Path
Upon entering the passage, you will encounter two pathways. Take the left path, which will lead you to a lift that descends deeper into the secret facility.

5. Navigate the Corridors
Continue moving through the twisting corridors until you spot a hallway marked with an “Escape” arrow. This may seem ominous, but it is part of the experience.

6. Follow the Escape Route
Proceed down the escape route. Initially, it appears to lead towards a scenario where Stanley meets an unfortunate end. However, just before this happens, a female narrator will interject, changing the course of events.

7. Enter the Museum Area
After the narrator takes over, you’ll find yourself dropped into the museum area dedicated to the Bucket. This section is filled with various displays showcasing game elements, additional cut content, and interactive developer commentary.

Overview of the Museum

The museum serves as a meta-commentary space, providing insights not just into the game’s new elements but also into its development process. It’s akin to a developer commentary mode found in many games, presenting a unique and immersive way for players to engage with the creative behind-the-scenes aspects of The Stanley Parable Ultra Deluxe.

Additional Notes

Keep in mind that this content is unique to the Ultra Deluxe version of the game, which has expanded upon the original by incorporating new endings and materials. Enjoy exploring the fascinating layers of this innovative work!
