6 ›A room that splits into 3 paths. The left or right side can be SS, depending on where the correct door is. Desks with their drawers open or crates can be PSS as long as you crouch behind them. The rock formation is also solid, so if you are on the side with the fake door and pressed against it and a wall it is also PSS.
4 ›The door is straight ahead. SS is to the left by the broken door. The corners are PSS (both the one with the item locker and the one with the crates.)
7 ›To get to the correct door, go straight then take a left turn. | SS: Anywhere in the sideroom, as long as you are not close to the doorway. | PSS: Against the wall with the doorway. Make sure you cannot see the outside of the room. Correct positioning for the PSS is shown in screenshot 3.
4 ›A room in the Normal roomtype consisting of a straight hallway followed by a 90-degree turn. This will always lead into a vent. One can hide in the vents so that they are not visible to either entrance or exit from the vents, as seen in image 4; This is PSS/SS. The green arrows point to the correct path.
