How to Redeem Codes in Deep Descent
Redeeming your rewards is a simple process that can be done directly within the game interface. Follow these four steps:

- Open the Menu: Locate the Twitter Bird (X) icon situated on the left-hand side of your HUD.

- Confirm: Click the Redeem button to instantly add the Cash to your in-game balance.
Frequently Asked Questions (FAQs)
There are usually two reasons a code might fail:
Case Sensitivity: Most codes are case-sensitive. Ensure “CASH!” is typed with the exclamation mark and capital letters.
Expiration: Codes are often tied to specific events or milestones. If a code has expired, the game will usually display an “Invalid” or “Expired” message.
The developers typically release new codes during major game updates, holiday events (like Halloween or Christmas), or when the game reaches a new “Like” milestone on the Roblox page.
No. Every promotional code in Deep Descent is for one-time use per account. Once you have successfully redeemed the 500 Cash from the “2025” code, you cannot claim it again.
For new players, we recommend spending your initial 1,000 Cash (from the two active codes) on Oxygen Tank upgrades or Stamina boosters. Staying underwater longer is the most effective way to earn more currency naturally through exploration.
