(adsbygoogle = window.adsbygoogle || []).push({}); Near the Juggernog Machine there are two windows, one next to it and one further away opposite it. Go to the one opposite one and stand in the entrance to that little room where the window is if you be quiet you will hear some strange noises and i heard a girl saying something (i had the music on at the time so i couldn't understand).

Where teleporter B is (where the GER plank is) go to where the mystery WOULD be (right from the teleporter) and look right into a building with a big hole in it move about a bit and you will see some shapes on a wall, i couldn't see what they were because i had a Browning and MG42 so i couldn't zoom in enough to see what they were.
Can someone confirm this?

I only find it sometimes

strange... ill look into this later nice find though
