THE MURAL SIMPLY REPRESENT THE STORY LINE WITH THE GOOD ENDING EXPOSED AND GIVES SOME OF THE CONDITIONS NEEDED FOR THE CHILIAD UFO TO SPAWN : Story complete ( Completeness (100%)) + Top of Mt. Chiliad location (Platform) + Weather : Lightning
What's the point of the other boxes with the Xs? Why include them when there is no choice to be made like the endings? You can't choose another route. The top 2 boxes are dead ends which makes sense, but the other boxes also lead to dead ends which doesn't make sense.
There's no route. It's an abstract representation of the story line. The key word is abstract here. Imagine a time line starting at the bottom of the mural and going all the way up. That's how the story line progress in reality , because time advance for all of them during that story line.
The red boxes are the major conflicts in that story. I explained it already , several times and in details . Judging by your other answers in other threads , you don't even like GTAV story line anyway. Do you actually do something else than trolling on these forums ?
