I have a cold seed glitch in alpha base where you can camp the entire map.
This is in bravo base right of the tunnel right next to the power box.
You camp the entire map
becareful though if you move to far forward you'll fall/die and if you move too far back your still vunerable to the people in the tunnels. it doesnt matter really where you are in the glitch you can still see the map but i recommend the spot in the picture.
