Redeem in this order
- Launch Zombie Air Force and finish the introductory tutorial if the account is new.
- Open Store from the left side. Some redemption guides describe that control as a shopping-cart icon.
- Scroll to the code box at the bottom of the Store window.
- Paste a single code with no quotation marks and no spaces before or after it.
- Press Redeem and wait until the result is obvious before you paste another code.
The current experience description tells players to use 1MIL, 2MIL, and TYFORPLAYING in the Store for free gifts. A fresh green beans group post tells players to use AC130, also with no quotes, for a gift. Enter the letters and numbers exactly as published. Guides that discuss case say a changed letter can fail. This site does not treat case as optional.
What the result can mean
A working redemption is reported to show the boost timer or the Credit payout immediately. If nothing changes, separate these cases before you retry:
- Extra characters. The official lines include the quote marks only to show the word. Do not type the quotes.
- Already claimed. Code lists describe one redemption per account. A second try of the same code is not a new reward.
- Expired. SORRY is on an October 16 expired list even though older posts and some same-day posts still called it active. GEMDROP and RELEASE are widely marked expired, without a published payout.
- Old server. The earlier THANKYOU and SORRY announcement said to use new servers. If that wording was attached to the code you are entering, join a new server and submit the same spelling once. Do not assume every later code has the same server rule. The current 1MIL, 2MIL, TYFORPLAYING, and AC130 lines do not repeat it.
Reward disagreements to expect
The live description says free gifts for 1MIL, 2MIL, and TYFORPLAYING. It does not itemize them. An October 16 roundup reports 2 Medals, 5,000 Credits, and a 60-minute 50% EXP boost for 1MIL and for 2MIL, and 1,000 Credits plus a 30-minute 50% EXP boost for TYFORPLAYING. AC130 is only described as a gift.
LITTLEBIRD and THANKYOU are still on some working lists. Their boost is not stable across reports: earlier posts say a Credits boost for 30 minutes, often written as +50 Credits, while the October 16 roundup says a 50% EXP boost for 30 minutes. Both versions also include 1,000 Credits. Read the in-game result instead of assuming either sentence.
FREE12 is reported as 1,500 Credits and a 15-minute XP boost, with +50% XP where a multiplier is stated. The October 16 four-code list left it out and did not call it expired.
After a code works
A timed boost is only useful if you deploy while it is running. Open the flight line, take the attack job you already know, and spend the window on dense groups. The Codes page keeps the string list. This guide is only the procedure and the failure cases.
