Buy the upgrade your last flight used

Pick a tree from the last flight

The developer advertises more than 180 upgrades. The useful cut is the branch for the weapon or airframe you just used. Read the Credit price on that node. If you cannot name the job the node improves, do not buy it to fill the menu.

Reported chain-gun nodes are Hot Barrel, Linked Belts, Twin Feed, Gatling Conversion, and HE-Frag Rounds. Reported rocket nodes are Airburst Fuzes and Pod Extension. Reported airframe nodes are Turbine Tuning, Kevlar Cockpit, and Armored Hull. A code roundup also mentions Twin Guns and Hot Barrels on the Apache tree. Hot Barrel and Hot Barrels may be the same heat node under two wordings. The screen label wins.

What each branch is for

Chain gun is the sustained crowd tool, and it overheats. Heat and feed nodes match the first-flight job. Rocket nodes match splash on clumps and shielded targets, which is the second attack to add. Airframe nodes are the durability branch when you are the one getting shot down, including Howler lasers.

Defense nodes belong to a placement you already use. Do not open a Cryo tree, if that pass is what your Store shows, until the squad has agreed who shoots the frozen group.

Respec and the October warning

A respec that refunds points into a new build is reported. Its cost is not published, so do not plan on a free rebuild. The October developer note says pre-existing content did not get a real balance pass and that new systems may be too weak, too strong, or too grindy. Re-open the node after that update and read the current price before you spend a large balance.

A simple order

  1. One chain-gun node if the M230 is your repeat attack and heat or uptime is the problem you felt.
  2. One rocket node if clumps or shielded targets are surviving the gun.
  3. One airframe node if you are leaving fights early.
  4. One defense node for an approach you already drop on.
  5. Stop and fly again before a second branch.

The Calculator payback form can turn a price you typed into a run count. It cannot tell you the node is good.

FAQ

Frequently Asked 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.
