1. Going back to "The Hatch".
Has anyone taken the sub and parked it directly on top of the hatch and tried to directly ascend? The reason I ask is because of how "The Bomb" is picked up in the Merriweather dock mission.
2. Has anyone tried to map the mural lines to map lines IN Los Santos?
At this point, I think its fair to say that the meaning of the Xs is entirely unknown.
3. I'm beginning to think that the mural refers to multiple parts of the map and IS NOT just a simple overlay. As with any idea, I could be smoking crack, but the glyphs don't directly map to anything on an overlay, so why not "SECTION" the mural into pieces.
a. The mountain (metaphorically a pyramid) + all seeing eye + lightning/radio signals + "return once your story is complete" seems to be linked to the Chiliad UFO.
b. The UFO, Egg, and Jetpack boxes don't appear to map to an object on the map. They seem relevant to the overall solution.
c. The lines don't appear to map to mountain cartography
