[help] stuck in sin episodes emergence

[angel-TDw!]

hey bro....
i went there through the stairs.....
cleaned up everything.... then came out of the window.....walked on the pipes...
that u can c above my gun pointer in the 3rd photo...then climbed down 2 the roof of the building ..then down...again....

Outside, shoot the guy on the right and go up the ladder, then the fire escape
to arrive outside the office windows. Inside are plenty of mercenaries waiting
for you. Take care of them and leave via the door to the staircase. Go up
(down is a med canister and the security station from earlier). Make your way
through the corridors and turn left into the conference room. Jump out of the
window, then onto the roof and finally the pipes on the left. Chat with JC
before dropping down to the bottom. Jump over the railing on the left side,
not into the deep end.

this is wot is written in the guide....
c the last line....but i cant do the stuff....

thanx
