ZA-6 Grimhawk

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.

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.

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.

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.

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.
