Credits, EXP, and the three listed buffs

Farm dense kills for Credits and EXP, then apply the group, friend, and weekend buffs without inventing a stacking formula.

Where Credits and EXP come from

Most Credits and EXP are reported to come from kills. The same coverage says the payout follows how many enemies you defeat, not how hard each enemy is. A chain gun held on a dense pack is therefore the farming pattern that matches the reported rule. Splitting the same minute across rockets, a sniper, and a shotgun is described as slower Credits per minute.

Mini-bosses are the exception people chase by mistake. The Flakmaw is reported to pay a 25 Credit bounty. That is real money, and it is small next to a packed wave if the bounty pulls you off the group.

Busier servers are reported to field fuller waves. The server cap on the listing is 10. You still need someone on the ordinary horde when a titan is up. Tunneling the titan as a full server is a reported way to lose the position even while the kill feed looks busy.

Lobby payouts

Published footage of the lobby describes three extra Credit sources:

  • Daily objectives in the Missions menu. One example on screen is Fly 15 km.
  • Playtime Rewards that build while you stay.
  • A Bounty Board that pays Credits and Medals.

A leave prompt reading HEY! WAIT! DON'T LEAVE! is reported to grant +50% Credits, +50% XP, and +1,000 Credits if you accept it. That is a lobby prompt observed in footage, not a code.

Paint Shop skins, name tags, and pilot voice packs such as Commander, No Voice, and Valkyrie are described as cosmetic. They are not reported to change the Credit rate.

Three listed buffs

Use each condition on its own. Nobody has published a stacking formula.

  • Group. The experience description says joining fresh green beans gives +10% XP and Credits.
  • Friends. Inviting friends gives a free XP and Credits buff. No percentage is printed.
  • Weekend. The description says play on weekends for an x2 buff. Gameplay coverage shows that multiplier on EXP and Credits. No timezone is printed, and the description does not say how it combines with the group percentage.

Check the live bonus indicator after the October update. The developer said older systems did not get a full balance pass.

Spending

Put Credits into the weapon or defense you repeated, then stop. The payback planner on the Calculator page is only arithmetic: the price you type, the extra Credits you think one run gained, and how long that run took. It does not know the live tree.

Medals are a separate reported currency on the Bounty Board and in the October 16 breakdown of 1MIL and 2MIL. Merits are new: the developer says wars pay them into a Warbond track. No merit price table is published.

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.
