Hi,
i am stuck at one of the places in penthouse mission where i have to go to adjacent building in zaverki's flat n all the city is in darkness plz tell me the way. i tried to go with the wires near the sign board but it didn't work.

That's where a zip line should be at. It's behind that bright reddish sign to the right. Go up the ladder and onto the catwalk behind it and look for a zip line that you can use to go across to the other building. You may or may not have to jump to get to it, I can't remember. But it's there.

hi,
ya when i want to go on the zip line it drops after half the way. so wt i should do.

Do you get dropped off it or does the line itself vanish halfway...? Strange indeed. Just make sure you don't press the jump button midway through (trying to raise your legs) causing you to let go of the line.

i have tried every thing but it drops half way. i am not pressing any jump button but still it drops is there any key point.

Sounds like some weird bug to me. I've never had that problem.

It's a known issue on PC version (which I'm guessing you have).

can any one tell me the cheats to get rid of this mission. mission penthouse

The same problem is being discussed in this thread:
