Are there Mulberry County codes?
No. Mulberry County does not use a traditional Roblox promo-code system. There is no code box on the main menu that grants rewards, currency, or items, because the game is a linear narrative horror experience rather than a simulator or tycoon.
The 8137 file code
At the end of the files on your desk in Chapter 2 is a locked Section 4. The combination is:
8137The clue is hidden in the lore: 137 refers to the day (the 13th) and year (1997) that ELC Inc was declared bankrupt, with the leading 8 completing the combination.
How to enter the code
- Progress to Chapter 2 and return to your bedroom after the woods.
- Interact with the files on your desk and read through to Section 4.
- Enter 8137 on the combination lock.
- Two additional document pages unlock, revealing more about ELC Inc and Project 12.
The De-classified badge
Entering 8137 correctly awards the De-classified badge ("Enter the correct passcode to gain access to extra documents."). It is optional and not required to finish the game, but it is the easiest collectible badge in Volume 1.
Codes FAQ
Will Mulberry County add promo codes later?
Nothing has been announced. Given the narrative design, traditional reward codes are unlikely, but Volume 2 could introduce new puzzle codes like 8137.
Does the code expire?
No. 8137 is a fixed in-game puzzle solution, not a time-limited promo code, so it always works.
Do I need the code to beat the game?
No. It only unlocks extra lore pages and the De-classified badge.
