Zombie Air Force Chain Gun Upgrades: Priorities and Spending

Last updated 2026-10-09Unofficial player article

Decide when chain gun upgrades deserve Credits, match a purchase to your combat task and preserve a reserve for the next relevant step.


Prioritize chain gun upgrades in Zombie Air Force when chain gun fire is the combat job you intend to keep using. If most of your next session will be rockets, air strikes or frontline defense, save toward that role instead of buying a gun improvement simply because it is affordable.

This introduction shows the aircraft combat setting behind the spending decision.

Decide whether chain gun fire is your main job

A beginner learning one attack at a time can reasonably put chain gun development first. That recommendation is about repeated use: Credits spent on the tool you use throughout the session have a clearer purpose than a purchase for an attack you rarely select.

If the squad already assigns you to defense support, keep that responsibility ahead of a chain gun branch. Likewise, a player intending to focus on another attack should not buy across every weapon branch merely to have something in each one.

Choose a purchase that addresses the gun task

When to prioritize or defer gun spending
Next-session goalSpending priorityReason
Keep chain gun horde coverage as your main jobPrioritize a displayed purchase that improves the gun task you use.The purchase connects to repeated combat work.
Learn aircraft handling and target selectionKeep practice as the first change.An upgrade does not choose a target or handle the aircraft for you.
Support the frontline with defensesKeep the defense goal ahead of unrelated gun spending.Your Credits follow the role the squad needs.

Match the actual purchase description to that goal. Do not assume a node changes range, ammunition, firing rate or damage unless the game says so. The selected effect and displayed price should explain the decision; a branch name alone does not make every purchase equally useful.

Keep a reserve for the next relevant step

Credits unlock progression within an offering of over 180 upgrades. A small balance does not need to touch every system immediately. Saving for one relevant gun purchase is a sensible editorial choice if the cheaper alternatives serve tools you do not plan to use.

After choosing the purchase, return to the same combat role so the next session has a clear purpose. If you still need a firing routine, use the chain gun guide. For the wider aircraft-and-frontline loop, read aerial combat.
