Okay so you can glitch out the map in that construction area, you can do so by using and angling the pallets in such a way on the staircase to the cylinder in the middle ish (right in front of where the pallets spawn) and then you use the angled pallets to get on top of the cylinder than use the pipe connected to it to get across and on the fence, go to the right of that warehouse building (it has a barrier) and then you can walk around out of bounds and then get to the end of the map and fall forever
