In this mission your secondary objectives are to tap all cams, as well as to interrogate a guy.
Not that hard one, just a few places you have to rush abit to reach certain stuff in time. You do have to knock out one dude to get one of the side objectives. You cannot interrogate a random NPC for the info, but atleast the one I ask has it. You see me quicksaving basically all the time, this is a "bad" habbit I have. you see towards the end that it comes back at me. Last thing, press space "asap" in the end, as there are enemies that could possibly spot you, but extracting (from a rather isolated place?) ends it and you're safe.
