Upgrade payback

Upgrade payback planner

Estimate how many runs it takes for one displayed Credit upgrade to pay for itself. You supply the in-game price and the extra Credits you expect from a run you can already clear.

Enter values from your session.

Payback cycles = upgrade cost ÷ extra profit per cycle, rounded up.

The sample numbers are blanks for the form, not Armoury prices. Type the Credit cost shown on the upgrade you are considering, then your own estimate of how many extra Credits one repeatable run would pay if that upgrade is the only change. The result is a payback estimate in runs and minutes. It does not read your balance, and it does not know weekend, group, or code boosts unless you already folded them into the extra-Credits figure.

FAQ

[UPDATE] Zombie Air Force ✈️ calculator questions

Is Zombie Air Force still in Alpha?

Yes. The experience description still says Alpha and tells players to expect bugs and imperfection. The developer, kobra, has also said the newest infantry, vehicles, and gunship work is early and may be too weak, too strong, or too grindy.

How many players are in one server?

The Roblox listing shows a server size of 10. It is a co-op PvE shooter: aircraft, dropped defenses, and allied ground pressure against zombie hordes and giant Behemoths.

Which codes does the developer currently name?

The current description names 1MIL, 2MIL, and TYFORPLAYING as free gifts in the Store. A developer group post adds AC130 for a gift and does not list the contents. Older codes such as LITTLEBIRD, THANKYOU, and FREE12 are still reported by some October 16 lists, but the live description no longer names them. SORRY, GEMDROP, and RELEASE have expiry reports.

Where are official announcements posted?

Join the fresh green beans Roblox group. The listing says members get +10% XP and Credits. A public write-up of the codes page says there is no separate Discord or Trello to follow, and no working invite for either was confirmed for this game.

What are Credits, Medals, merits, and Honors for?

Credits buy aircraft, weapon, and defense upgrades. The developer says there are more than 180 upgrades. Medals show up in reported code rewards and on the Bounty Board. The October update adds merits earned through wars for a Warbond-style track. Honors is named only as something the Grimhawk access description says you do not need.
