I found the monitor above using hackmover. Like the previous secret telepad it shows on the maps but it's not documented in the strategy guide. I also don't know how to get in there without using hackmover. The only possible door seems the wallspace next to the camera at the elevator but I haven't found a bloody switch to open. I recall finding an orange keycard which is not used anymore (though I can't recall where I found it), maybe it's related to this. What the monitor does is opening the door to the final elevator, allowing you to skip the last portion of this mission. Anyone know how to access this room?
