Jump into the hole, being wary of the headcrab that's just around the corner, and you'll come out in the control room. None of the open cells around here have anything in them, apart from the only lit one on the bottom floor which has a hole leading through to an old, battered control room. Head to the stairs at the far end and go down them. Through the door you'll get a look at just what state the place is in - it's been around for a long time, that's for sure. Start by breaking the two supply crates by the door to get some SMG ammo. Your first look inside the eerie Nova Prospekt.
