when bromley gives u a gun the first thing you should do is go to the place where you came in and beetween the staircase are doors walk up to them and they pop open shoot the 2 guys then go left or right there should be a door on 1 side go into the door and youll walk into the kitchen there will be a staircase leading up there are four guys when you get fully up there then there is a hall full of doors go to the second to last pair go in the right then there will be a padio go on it shoot these guys and you will see bromley after you talk to him a bus will pull up jump onto it and there ur done! hope this clears things up because my hand hurts. CHEAT ON YEAH!
