Expired codes
(none)— No codes are known to be expired right now.
Why codes might not work
- The code has expired. Event and holiday codes often stop working without warning after a short period.
- There is a typo or extra space. Codes are case-sensitive, so every letter, number, and symbol must match exactly.
- The code was already redeemed on your Roblox account. Most codes can only be used once per account.
- The game server or your client is outdated. Close the experience, rejoin a fresh server, and try the code again.
Where to find more codes
New Zombie Merge Turret Defense codes are usually released to celebrate updates, events, or milestones. To catch them quickly, you can:
- Join the official Nova Impact Studio Roblox group, where announcements about the game and rewards are posted.
- Check the game’s description on its official Roblox experience page for any codes added by the developer.
Bookmark this page — code lists are reviewed and refreshed on a regular basis.
Remember that codes are free, time-limited bonuses. Always enter them exactly as written, and avoid any third-party “code generators” or sites that ask for your password or personal details, as legitimate codes are only shared through official channels.
