I make my way back to base and find out I need to go find my brother held up in his apartment. Upon leaving im flown out to a new map. I didn't realize right down the fire escape is his room and I walked around the map for awhile looking for how to find the brother. Then realized it was just down the first flight of stairs I started on in the beginning of the level facepalm.. lol
Doing some side missions I take out some baddies and then find my way into the apartment to do the main story line. Going into the main entrance to the hotel I would think I could get to the brothers room but it seems I cannot without knowing which door is his.
