Mount Chiliad's History

A man looks out over the city in GTA 5

Mount Chiliad was claimed by the Spanish in 1769, taken under Mexican control in 1821, and remains in American hands since 1847.

“Claimed by the Spanish in 1769, Mount Chiliad is the highest peak in San Andreas, sitting at a height of 2,744 meters”

The UFO Revelation

After 100% story completion, standing atop Mount Chiliad at 3 a.m. during cloudy weather reveals a UFO with an F.I.B. logo.

“It's marked with an F.I.B. logo, aka the Federal Investigation Bureau, implying that it was created by the government”

UFO Behavior

The UFO doesn't react to bullets and raindrops nearby become pixelated, suggesting it's not a physical object.

Hologram Theory

Hologram Theory

The UFO is likely a hologram, unlike the two functional UFOs in the game that emit electromagnetic pulses.

“The running theory is that it's a hologram, as opposed to the two other functional ufos in the game”

Mural Clues

A mural at the summit shows an eye at the top, lightning bolts on the exterior, and a maze of lines connecting to eight squares.

“Inside the mountain is a maze of perpendicular connecting lines. Each one connects to one of eight squares”

The X's and Petroglyphs

Five X's on the mural correspond to petroglyphs hidden around the mountain, each depicting a weather status for the UFO to appear.

“The community worked out that the X's correspond to petroglyphs hidden around the mountain, each of which depicts a weather status required for the Mt. Chiliad UFO to appear”

Jetpack Theory

Jetpack Theory

The jetpack drawing on the mural may refer to the UFO above Fort Zancudo or a jetpack vehicle in GTA 5's single-player mode.

“In the gta online mission involving the nuclear facility, the player escapes by using a jetpack”

Cracked Egg Mystery

The cracked egg on the mural has theories linking it to the Epsilon cult, the Maze Bank Tower fountain, or an underwater UFO in Paleto Bay.

“It could refer to the Epsilon cult, as they believe the world hatched from an egg”

Subreddit Creation

One week after GTA 5's release on Sept. 24, 2013, fans created the Chiliad Mystery subreddit to solve the mystery.

YouTuber Gator Keys claimed the mystery is a satirical take on real life, with the government being all-seeing and all-powerful.

“The answer is essentially that the government is all-seeing and all-powerful, as represented by the F.I.B. logos on the UFOs and the eye on top of the mural”

Longevity of Mystery

GTA 5's unsolved mystery has engaged players for 13 years, with new theories emerging even in the last year.
