Overview
General Route
Challenge Mode Specific
This chamber is one of the few Challenge Mode chambers to utilize Out-Of-Bounds. The beginning of this chamber is the same as the normal route, however instead of portaling over to the button, the player will place a portal at the bridge and another in line with the first Laser Receiver. From there, the runner will fire a shot through a gap in the model of the Observation Room and portal into the room. Once in the room, the runner will make their way to the left corner and place a portal on the ceiling. From there, they will shoot the portal that was in line with the receiver onto the bridge portal surface. Ensure that the floor portal is as straight as possible, as this will aid with getting out-of-bounds.
After that, hold a directional key so that you're pressing into the corner of the room, and fire the opposite portal in the general area highlighted in the image.
Because of the inconsistent nature of the orientation of these portals, an exact lineup is not used, and a general area is applicable. If done properly, the bridge will push you out-of-bounds, ontop of the exit room. NOTE: Ensure that you have r_portal_use_pvs_optimization set to 0 to see Out-Of-Bounds. Once you're out of bounds, move to the edge of the floor, and slightly move off of it. Once falling, quickly strafe back inwards and place a portal on the surface underneath the door. Jump off the bridge provided from the portal, and strafe into the flags.
