Roblox Terminal Escape Room Chapter 3, titled Descent, places players inside a stalled service elevator following the train explosion in Chapter 2. Developed by CCF Studios, this chapter separates multiplayer team members into individual elevators at the start, requiring each player to decode a randomized elevator code within a 15-minute time limit before the elevator cables snap. After exiting the elevator, players enter a central hub area beneath an unstable ceiling with a 75-minute limit to solve four branch puzzle rooms, unlock the Nursery, and escape.
Elevator Puzzle Walkthrough
Each elevator generates a unique combination, meaning static codes from external playthroughs will not work. Players must read the elevator interior posters from top to bottom to solve four separate digits.
In Standard Mode:
- Look upward, open the ceiling emergency hatch, and climb the ladder to the top of the elevator cab. Examine the lit symbols on the shaft wall. Decoding the Pigpen cipher against the elevator chart translates to "Count the triangles." Count every triangle drawn on that wall to determine your first digit.
- Return inside the elevator and inspect the "How to read Braille" chart. Look at the illuminated light pattern near the ceiling. Match the light grid to the corresponding Braille numeral to find the second digit.
- Locate the "Iguana Identification" poster on the elevator wall. Compare the pattern of eight illuminated light blocks on the elevator floor with the iguana tail charts on the poster. Match the light and dark segments from right to left to identify the matching tail number, which supplies the third digit.
- Check the "Archery Practice" poster and examine the concentric markings on the elevator carpet. Identify the red-highlighted rings, match their point values on the archery scoring chart, and add them together. The resulting sum is your fourth digit.
- Input the four digits into the wall keypad to open the elevator doors into the main chamber.
In Beginner Mode, the elevator hatch uses illuminated border segments that spell out a direct four-digit number when read across the wall edges. After climbing to the roof, players count shapes according to four wall posters: circles for digit one, triangles for digit two, squares/rectangles matching the elevator rug for digit three, and stars for digit four.
Standard Mode Hub Room Solutions
Exiting the elevator leads to a circular corridor connecting four dedicated puzzle rooms and a sealed Nursery door requiring four keys. Players need to collect eight colored boxes, eight paint cans, eight newspaper pages/posters, and four arcade coins scattered throughout the hallways and unlocked rooms.
Box Room (Code: 6824)
Collect all eight colored boxes and enter the Box Room. Place the boxes onto the storage racks according to the layout dictated by the Math Pages and App Design Pages found throughout the circular corridor:
- Math Pages display the required color placement on the shelf.
- App Design Pages indicate which item icon must show on the visible face (such as pillows, plates, nails, knives, soap, and bleach).
- Rotate each placed box until the items match the App Design specifications.
Once all boxes sit in their correct color positions and orientations, step back to view the white lines etched across their faces. The lines form the digits 6, 8, 2, and 4. Enter 6824 into the locked container to claim the Blue Paint Can, Key 1, Coin 1, and a poster page.
Paint Can Room (Code: 5431)
Gather all eight paint cans and enter the painting room. The large wall canvas functions as a paint-by-numbers grid. The color numbers appear on walls across the facility:
- 1 = Blue
- 2 = Yellow
- 3 = Purple
- 4 = White
- 5 = Orange
- 6 = Black
- 7 = Green
- 8 = Red
Apply the colors to every numbered tile until the full image is complete. Next, inspect the "All Finished Painting" poster on the room's right wall. The paragraph conceals four color names: purple, orange, blue, and red. Check the remaining liquid levels in the tubes beside the completed canvas from right to left:
- Purple: 5 ml
- Orange: 4 ml
- Blue: 3 ml
- Red: 1 ml
Enter 5431 into the wall keypad to open the metal toolbox, retrieving Key 2, Coin 2, and another poster page.
Newspaper Room (Code: 7083)
After collecting all eight poster pages, go to the Newspaper Room. A newspaper on the counter displays underlined shape names: Plus, Square, Triangle, and Minus. Align the collected poster pages inside the viewing slot to read the clues associated with those four symbols in that specific sequence:
- Plus ("The number of yellow paint squares"): Count the yellow squares filled during the paint puzzle, which equals 7.
- Square ("The shape of the main room"): The blueprint in the Box Room shows the circular central chamber, corresponding to 0.
- Triangle ("The number of brown boxes without an X"): Count the plain brown boxes in the Box Room, which equals 8.
- Minus ("How many arcade games have the letter N"): Inspect the arcade cabinet names in the Arcade Room. Orange Juice Tycoon, The Grass Is Always Greener, and Fishing Sim: The Yellow River contain the letter N, totaling 3.
Enter 7083 into the room's numpad safe to unlock Key 3 and Coin 3.
Arcade Room (Password: CHAINS)
Retrieve the fourth arcade coin by jumping onto the orange arcade cabinet. Insert one coin into each of the four powered arcade machines to register ticket values: Player 1 (5 tickets), Player 2 (15 tickets), Player 3 (100 tickets), and Player 4 (50 tickets).
Examine the prize counter board to check the highest-tier prize affordable for each score, then isolate the capitalized letters:
- 5 Tickets: CHip clip
- 15 Tickets: pAnIc button
- 100 Tickets: rubber sNake
- 50 Tickets: the beSt slime
Combine the capitalized characters to form the password CHAINS. Enter CHAINS into the counter cash register to release Key 4.
Standard Mode vs. Beginner Mode Progression
The core puzzle layout changes depending on the mode selected in the main lobby. The table outlines how each section operates across both difficulties.
| Area / Stage | Standard Mode Requirements | Beginner Mode Requirements |
|---|---|---|
| Elevator Exit | Decode Pigpen, Braille lights, iguana tail bars, and archery carpet circles. | Decode border light text, then count wall circles, triangles, rectangles, and stars. |
| Outer Room Doors | Doors remain open; items are collected freely across the circular corridor. | Doors require four-digit codes: Storage (4781), Art (4213), Newsroom (4896), Arcade (2514). |
| Storage / Box Room | Shelf color and app icons reveal code 6824. | Box color shelves reveal 5923 for the chest and 4695 for the blue paint container. |
| Art / Paint Room | Fill the full grid and measure remaining paint levels for code 5431. | Fill numbered colors on the wall to reveal the static code 8450 on the easel. |
| Newsroom Puzzle | Cross-reference Plus, Square, Triangle, and Minus clues to enter code 7083. | Match Plus, Minus, Diamond, and Square clues from collected notes to enter code 7849. |
| Arcade Register | Combine prize uppercase letters from individual ticket tiers to spell CHAINS. | Subtract ticket costs (100 - 50 - 35 = 15) to identify the prize word SUCKER. |
The Nursery Final Puzzle (Code: 0743)
Take all four keys to the locked black door in the main corridor. Insert the keys to access the Nursery.
Inside the Nursery, four columns of alphabet blocks stand between red platforms. Read "Ms. Potata's Clean Up Rules" on the wall to determine block orientations:
- Column 1 forms the word CLOUD.
- Column 2 forms the word SPAC3 (or SPACE).
- Column 3 forms the word OCEAN.
- Column 4 forms the word PL4NT (or PLANT).
Locate the themed posters placed on the walls adjacent to the red platforms. Climb each red platform to look directly downward from above:
- Above the Ocean poster platform, the red blocks shape the number 0.
- Above the Cloud poster platform, the red blocks shape the number 7.
- Above the Space poster platform, the red blocks shape the number 4.
- Above the Plant poster platform, the red blocks shape the number 3.
Climb to the top of the central red pillow tower, enter 0743 into the keypad, and press the green button to power the exit elevator and finish Chapter 3.
Frequently Asked Questions
Why does my elevator code not match other walkthrough guides?
Elevator codes in Chapter 3 are randomized for every individual elevator instance. Both Standard and Beginner modes generate custom parameters for the shapes, lights, and floor patterns, requiring each player to decode their own values using the posters inside the cab.
What is the password for the arcade cash register in Standard Mode?
The cash register password in Standard Mode is CHAINS. It is derived by taking the uppercase letters displayed on the prize chart for the 5, 15, 100, and 50 ticket prizes (CHip clip, pAnIc button, rubber sNake, and the beSt slime).
How do you find the fourth arcade coin in Chapter 3?
The fourth arcade coin sits on top of the yellow arcade cabinet inside the Arcade Room. Jump onto the cabinet from the adjacent counter or machine to pick it up.
