The Deadzone Node is a game mechanic in Unturned.
When created in the Map Editor, it creates a permanent radioactive field around the node. The size of the Deadzone can be adjusted.
When a Player enters a Deadzone, a message saying "Entering deadzone" will appear and their Immunity will drop rapidly. If the Player exits the Deadzone, the message "Exiting deadzone!" comes up on the screen.
Gasmasks and Biohazard Hoods will block out radiation from deadzones, but will eventually need to be repaired with a filter to continue to filter out radiation.
