I'm thinking the bus door at canyon wreckage will be open or something and i'm thinking there will be a very small open area (similiar to how you have to go through the tunnel in honest hearts) and you must walk a very small distance and you will find a rock wall with a large blast door on it with a stars and stripes emblem on it and once you enter this, there is an underground tunnel that is dead quiet and has a lot of graffitti and at the end of the tunnel there is a door that takes you to the divide...... just my theory :celebration: :foodndrink:
EDIT: After watching the video again, i think the tunnel will lead to a window where you can see ulysses and the missile........once again, just a theory.......
