Hold the ground

Zombie Air Force Defenses

Zombie Air Force defenses connect your aircraft’s support to the ground your allies are trying to hold. Start with the defense overview, then separate placement decisions from upgrade decisions. The Cryo Emitter adds a specific option: its official pass describes pulses that freeze nearby zombies and a dedicated upgrade tree.

Access and progressionTreat a defense unlock and its upgrade plan as separate choices.

Give the defense a job the aircraft can support

A defense plan starts with the pressure you want it to cover. Choose a part of the frontline that needs attention, tell the squad why it matters, and keep someone responsible for ordinary horde pressure while other players focus on larger enemies. The placement guide develops this decision without turning a useful support idea into a rigid route everyone must follow.

For Cryo Emitter planning, separate access from later improvements. The official pass sells access for 299 Robux and describes nearby pulse freezing; the dedicated tree is a further progression choice. Decide whether ground control is the responsibility you want to take before making that purchase. Then use the upgrade guide to connect your next improvement to the same support goal, rather than treating an unlocked defense as a finished build.
