Credits are the currency that keeps you alive in Survive Zombie Arena, and codes are the fastest way to stock up on them without grinding waves. Redeem the active ones below to buy weapons, upgrade damage, and unlock classes before the horde gets harder.
Quick answer: Open the Shop menu, scroll to the codes box at the bottom, paste a working code such as DELAY, and press Redeem. Your credit balance updates the moment the code is accepted.

You know it worked when the credits are added to your balance and, for crate codes, the Bloodmoon Crate lands in your inventory. Repeat the process with each remaining code, one at a time.
Why a code might not work
Most redemption failures come down to a few fixable causes. Run through these before assuming a code is dead.
- The code expired. Compare it against the active list above and drop any that are no longer listed.
- A typo or wrong capitalization crept in. Copy and paste instead of typing by hand.
- The game just updated. New codes sometimes arrive alongside a patch, so wait for servers to reset before trying again.
- The code was already claimed on your account. Each code redeems once per player.
What credits and rewards do
Credits are the core currency you earn by clearing zombie waves, and codes hand them to you directly. They feed straight into your loadout across three areas.
| Reward | Use |
|---|---|
| Credits | Buy weapons for your four weapon slots, upgrade damage, DPS, and fire rate, and unlock new classes. |
| Bloodmoon Crate | A crate reward tied to update codes, claimed straight to your inventory. |
| Void Shards boost | Doubles Void Shard gains for 24 hours after redeeming GALACTIC. |
You can also spend credits mid-battle on barricades, auto-turrets, and landmines to hold a position, so a fresh code top-up gives you more room to experiment with defensive builds.

Where new codes appear
Fresh codes tend to drop when new content goes live. The official Survive Zombie Arena Discord is the primary place developers post them, and it also carries patch notes, polls, and giveaways. Keeping an eye on the Nectarforge Studios Roblox group is a solid backup for update news.
Because releases are inconsistent, check back on the active list above whenever a new wave of content lands and redeem quickly. Update codes like DELAY and UPDATEDAYSWAG carry the best rewards and often expire soonest.
