How to Redeem Codes in Fortress Frontlines
- Launch Fortress Frontlines on your device.
- Open the main menu or the settings panel by selecting the gear or profile icon.

Why Your Code Isn’t Working
- Case Sensitivity: Codes are usually case-sensitive. Ensure you are typing capital letters exactly as they are shown.
- Expiration: All codes have a limited shelf life. If a code has passed its redemption window, it will no longer grant rewards.
- Redemption Limits: Many codes are limited to a single use per account. Check if you have already claimed the reward previously.
- Typing Errors: Copying and pasting is the safest way to enter codes to avoid common typos like mixing up zeros and the letter O.
