Project Zomboid Helicopter Event (Build 42)
The helicopter comes once a game has run 6 to 9 nights — the night is picked at random when the world starts — and arrives inside a window that opens between 9:00 and 18:00 and stays open for 1 to 4 hours. That day the emergency broadcast adds “Air Activity detected.” after its forecast. Whether it ever comes back depends on the “Helicopter” sandbox setting.
Timing, settings and radio text from the Build 42 server's code (depot manifest of 23 Sept 2026); effects and tactics adapted from PZwiki, Helicopter (CC BY-NC-SA 3.0).

How often, by game mode
| Game mode | Helicopter setting | What that means |
|---|---|---|
| Apocalypse | Once | One visit, after 6–9 nights. |
| Extinction | Sometimes | First after 6–9 nights, then again 10–15 nights after each visit. |
| Outbreak | Once | One visit, after 6–9 nights. |
| Rising | Never | No helicopter. |
| Six Months Later | Once | One visit, after 6–9 nights. |
In a custom sandbox the same setting offers Never, Once, Sometimes, Often: “Sometimes” schedules the next visit 10–15 nights later, “Often” 6–9. The game's tooltip: “How regularly a helicopter passes over the Event Zone.”
What it does
You never see it — the helicopter is invisible — but zombies across a huge area hear it and walk toward it. In multiplayer it picks one player. If it does not see you it searches the area around you; if it spots you, it hovers over you for about 60 real seconds before flying on (the code gives it a 100-square search radius and a 50-square hover radius). It can come back a couple of hours later, and the zombies it draws keep walking after it leaves, so cleared ground is not safe again that day (PZwiki, Helicopter).
How to survive it
Stay in and hide
The easier way. Have a day of food and water, something against boredom — skill books, or tapes and a TV — cover every window and keep the lights off. A basement is best. The cost comes later: the area around your base may be full of zombies the helicopter pulled in.
Drive away
Riskier, but it pulls the crowd away from home. That morning, fill a reliable car's tank, pack a day of food and water and drive slowly through the wilderness all day. The helicopter will find you; the zombies it draws end up far from your base. Come home by a different road, and expect to drive back in the dark.
