Survey 01-480x270


Surveying is the act of identifying Buildings, Enclaves, Vehicles, threats (Hordes, Infestations, Freaks) and other elements from a high vantage point called a Survey Point. There are multiple Survey Points scattered thoughout Trumbull County.


Climb to the top of a Survey Point and enter aim mode, then hover the crosshair over Question Mark icons. Wait for the circular meter to fill around the question mark, indicating surveying progress. Once meter is filled, the question mark icon will change to the name of the identified element (such as "Vehicle", "Horde", "SWAT Zombie", "House" or "Storage"). In addition, an icon representing that element will be placed onto the player's map.
