There are many mysteries yet to be uncovered in GTA 5. Having such a huge open-play map, there are plenty of things to look for in Los Santos. Players who are sci-fi freaks are in for some great news.
The mystery behind Mount Chilliad has been solved; at least for the most part. If you are one of Los Santos explorers, you should be able to recall that huge ‘illuminati’ poster depicting Mount Chilliad with three boxes right at the bottom representing an egg, UFO and a jetpack.
We all know where to find the UFO. As for the egg, there is actually a cave under a remote village on Mount Chilliad itself. A video got uploaded to YouTube which actually reveals everything. It all make sense now.
Looking at your map right at Mount Chelliad, there is an unchartered gap that shapes like a UFO. Travel to that region. Best mode of transport is with an aircraft.
Once there, search for the village. It is close by. The moment you found the village, the folks there will shoot you while affiliating you with the government. It is much easier if they are all dead so kill them all.
The moment there is a dead silence, circle the village downwards and you should spot a cave with mysterious markings around it. This is a big clue to the egg. We are definitely nearing its discovery.
As for the Jetpack, another video got uploaded to YouTube suggesting it to be in Fort Zancudo. There have been plenty of discussions on the mysterious elevator in the military base which can only travel underground. The video shows a player going underground with a helicopter trying to unmask the mystery.
A black square tile is found underneath the elevator believed to be a hidden room that contains the jetpack. However, some players refuse to acknowledge this suggestion calling it to be the beams that supports the UFO coming at 3am.
It is still unproven but with evidences like these beginning to pop out, it will only be a matter of time before a GTA 5’s Dora the Explorer and Mythbusters make another major discovery.
