I have once again found my brother. He is accross from me on a balcony fighting and ask me to join him at the front gate. OK....now, I have slid down to a lower balcony, ran up wall and pull down on rail to rise a column. Jumped on to column to other balcony, again ran up wall to grab other rail. Another higher column rises. OK...now I jump to activiate the button on the wall, jump back between the two columns but can NOT get to the door to crawl under in time. Have tried for 2 days but not enough time to reach the door before it closes. Whats the secret to keeping the door open long enough to crawl under and move forward. Very frustrated. Help needed.
