In Grand Theft Auto 5 Mount Chiliad stands as the highest peak in San Andreas at 2,744 meters. Beyond its sheer size and history—claimed by the Spanish in 1769, taken under Mexican control in 1821, and held by Americans since 1847—the mountain became famous for hosting one of gaming's longest-running community investigations.
Quick Facts
- Location: Mount Chiliad, San Andreas (highest peak at 2,744 meters).
- Community Hub: The Chiliad Mystery subreddit was created on Sept. 24, 2013, one week after the game's release.
- The Mural: Found inside the summit tramway station, depicting an eye, lightning bolts, a maze, a UFO, a cracked egg, and a jetpack.
The Mount Chiliad Mural and UFOs
Players achieved 100% story completion can stand atop Mount Chiliad at 3 a.m. during cloudy weather to reveal an F.I.B.-marked UFO hovering in the night sky. While players initially hunted for a permanent single-player jetpack and other hidden features based on the summit mural's cryptic drawings, ongoing investigations and datamining over the last 13 years revealed no game files hinting at a flyable UFO or single-player jetpack.
Instead, community theories have linked the mural's five X-marked squares to petroglyphs indicating weather conditions for the Chiliad UFO, or to the 50 collectible spaceship parts scattered across San Andreas. Other elements, like the cracked egg, have been widely theorized to point toward the Paleto Bay underwater UFO or the Epsilon cult.
What It Means for Players
Though YouTuber breakdowns and community sleuths like those on the Chiliad Mystery subreddit have largely concluded that the mystery serves as a satirical nod to government surveillance rather than a grand mechanical puzzle with a secret vehicle reward, the ongoing hunt created a massive, collaborative community. As players look toward the release of Grand Theft Auto 6 the 13-year pursuit remains a defining example of how environmental lore and Easter eggs can keep a player base engaged long after a game's initial launch.
