I can't be the only one stuck on a part in Half Life (at least I hope not) so I thought I would start this thread. My problem: I just got inside the citadel and I have no idea how to proceed. This pics, I hope, provide a better a description of my current surroundings:





I don't see any ladders or anyplace to drop down to so I am hoping that someone might help me figure out where to go. Much appreciated. Thanks
