In this game your health bar will be very crucial and will be emphasized from the beginning to make sure you are observant of it at all times. Since I picture the game being military based I can see the armor system being either the same or very similar to how  Call Of Duty: Warzone has their armored plates. You can find them all across the map as you are looting and only have to hold a button to be able to put one on. I am not sure if I want to have up to three armored plates or just one.
