Perfect Dark/Unused Content By Level/Skedar Ruins

Unused Pads
There are two pads for what likely would have been an elevator platform in the room with the object used to activate the bridge. The first pad is slightly above floor level in the room, while the second is a short distance below the room in the void.

Unused Text
Obtain Scanner. Scanner Picked up Scanner. Text for a Scanner device. While they may have been intended as rename strings for the R-Tracker Joanna begins the mission with, they're not assigned to it, and the Scanner is a device known to have been in the game at one point. It would allow Joanna to identify objects, displaying a readout with their properties at the bottom center of the screen.

WAR!
WAR's selection icon is based on a pre-release screenshot. It's using the game's default dark sky with red clouds. In the final version, both Skedar Ruins missions have a skybox, which gives the mostly blue sky a rainbow appearance towards the horizon.
