What console are you on?
Which mission are you on?

If you are talking about the Penthouse mission and are looking for extraction, it's not via the helicopter that you first encountered on your way to the penthouse. The extraction point is in the elevator that the technician was working on when you first entered the second building.

Go to the area with the spiral staircase. Straight across from it is an opening with a red light emanating from it. Go in there, find an opening on the top of the elevator and drop into it - extraction!

hi any one help new to the psp got splintercell essentials stuck at the start of the cargo ship to blow up the conteners not sure what to do or where to go.
