Zombie Air Force game passes
Six passes exist at launch. Credit Boost is the best single buy; the Starter Pack is the best catch-up bundle; the MH-6 Little Bird launch sale ends October 15, 2026 at 18:00 UTC.
Zombie Air Force runs six official game passes at launch — the icons below are the official pass artwork from the game's store. None of them are pay-to-win in the sense of buying power you cannot eventually earn — but two of them (Credit Boost and Starter Pack) change how fast your account moves, and one of them, the launch-sale Little Bird, is time-limited.
All six passes
| Pass | What it unlocks | Notes |
|---|---|---|
 Grimhawk Fighter Jet | The ZA-6 Grimhawk strike fighter, unlocked instantly | Upgrade tree still earned in game; no credits, medals or honors needed to get the plane |
 Starter Pack | Vanguard skin and name tag, +50% credits forever, 25k credits, 3 medals, 3 honors | The best early-progression bundle |
 Spec Ops | Four Apache digital camo schemes: Night Ops, Urban Digital, Woodland Digital, Desert Digital, plus 15k credits and medals/honors | Cosmetic + currency bundle |
 Cryo Emitter | A special defense that freezes every zombie around it in pulses, with its own upgrade tree | Adds a new defensive tool, not just a skin |
 MH-6 Little Bird (Launch Sale) | Instant MH-6 / MH-9 Little Bird with no level requirement | Sale price ends October 15, 2026, 18:00 UTC — after that the price increases |
 Credit Boost | +50% credits every battle, forever | Stacks with weekends and the group bonus |
How to choose
- If you only buy one thing: Credit Boost. It is the only pass whose value compounds every single session, and it stacks with the weekend ×2 and group +10% bonuses.
- If you are new and want to catch up: Starter Pack bundles the same boost with currency, medals and honors — it is the "skip the first week" button.
- If you want a different flying experience: the Grimhawk is the strike-fighter fantasy, the Little Bird the fast helicopter one.
- If you defend instead of attack: the Cryo Emitter is the only pass that adds a defensive system rather than a stat.
The launch sale is time-limited
The MH-6 Little Bird pass carries an explicit expiry from the developer: the launch sale ends October 15, 2026 at 18:00 UTC, after which the price increases. If you are deciding between passes and the Little Bird is on your list, that deadline is the only one on the clock.
FAQ
Are Zombie Air Force game passes pay-to-win?
They are pay-to-progress-faster, with one content exception: the Cryo Emitter adds a defensive tool other players do not have. Everything else — the Grimhawk airframe, the Little Bird, cosmetics and boosts — is either earnable in game or purely cosmetic.
Does the Grimhawk skip the upgrade grind?
No. The pass unlocks the airframe instantly, but its upgrade tree is still earned in game, exactly like every other aircraft.
Do passes ever go on sale?
The Little Bird shipped with a launch sale that ends October 15, 2026, 18:00 UTC. The developer has not announced other pass sales.
