Trivia Edit

The 2 rooms which contained the Bubble. G. and PadShield are actually still in the current version of the map, however, all light was removed from them and they are only accessible through the /noclip command. There is a sinister flashlight pointing at a key, which is probably a test of the key that opens the cell door upstairs once stepped on.
