When a player first joins Overthrow they are allocated a random house in a random city, town or village on the map. When the player dies they will respawn here. Your home can be changed easily to:
To change home you must physically be at the location, it cannot be done remotely. For a house, use the "Real Estate" menu. For an FOB or base, use the action menu on the flag.
You can also Fast Travel to any of the above (including your camp)
