open it and jump in, it's nice to die in the blue fog. i can't remember but i think u can open the trap if u shoot the buttons.
u right there are 2 lifts on both sides on the map (the map is mirrored). between the lifts (the tunnel from tunnel to tunnel) is a hole in the floor with a teleporter to the room with the quad! if you jump is this hole while some other press the button u'll jump in ur death :) (a trap!) but ur enemy must been realy close to you because the button is close to the hole (in the small room with the computers) there is also a megahealth behind the computers!
p.s. sorry about my bad english i hope u understand what i talked about ;)
The PG room was rather pointless. Such a large room, with such dangerous things below, is hardly made worthwhile by the inclusion of a meagre RA and a PG. Putting the RG back there could have worked great. The "anti-camper" measure is also a bit extreme. The rockets will fire even if you jump off right away, perhaps fragging the poor soul who followed you down the pipe instead of you (even though neither of you were camping). Gets a 7 from me...cool looks, but the map that inspired it can't possible have been that good.
