It is enabled until you equip your gun or engage in combat allowing you to be in 3rd person when travelling and doing looting etc.
It is always enabled in a car.
Free look in 3rd person, so you can look at your awesome survivor (I believe we allready have this confirmed for 1st person.)
Also to counter camping a spot, you could have it so when your characters face is into an object, the 3rd person will zoom in drastically/ go back in 1st person.
I also still think there should be option for: Full 3rd person server, 1st person only, and balanced 3rd person.
Made this in a hurry.
