You're driving through Blaine County at 3:00 AM. It’s raining. Suddenly, a neon green glow pulses from the top of Mount Chiliad. Most players remember that first time they realized Grand Theft Auto 5 aliens weren't just a throwaway joke or a hallucination from Michael’s bad trip. Rockstar Games didn't just put a few Easter eggs in the game; they built a sprawling, decade-long mystery that honestly feels like a second job for some of the community’s most dedicated hunters.
It’s weird.
For a game about stealing cars and committing high-stakes heists, the obsession with extraterrestrials is staggering. It started with a mural. You know the one. That cryptic drawing at the cable car station on Mount Chiliad that looks like a cross-section of the mountain with a UFO, an egg, and a guy in a jetpack. People lost their minds. They spent years—literally years—trying to "trigger" the mural’s secrets. Some thought it was a map. Others thought it was a schedule. Turns out, it was a little of both, but mostly it was a massive rabbit hole that led to some of the most complex secret-hunting in gaming history.
The Mount Chiliad Mystery and the 100% Barrier
Basically, you can't even see the most famous Grand Theft Auto 5 aliens until you've basically conquered the game. It’s a reward for the completionists. To see the UFO hovering over the peak of Mount Chiliad, you have to hit that 100% completion mark on your save file. Even then, it’s picky. It has to be 3:00 AM, and it has to be raining or stormy.
If you meet those criteria, a holographic UFO appears.
It has "FIB" written on the side, which suggests it might just be human-made tech, but the implications are still creepy. However, that’s just the tip of the iceberg. There are other ships. One sits at the bottom of the ocean off the north coast, rusted and covered in seaweed. Another hangs silently over Fort Zancudo, projecting a weird light beam onto a bunker at night. Then there's the one over Sandy Shores, decorated with "Lose Pole" (an anagram for "Pole Loser") and other bizarre markings.

Why the GTA 5 Alien Mystery Is Different from Other Games
Rockstar is the king of the "slow burn." In most games, an Easter egg is a one-and-done thing. You find it, you take a screenshot, you move on. With Grand Theft Auto 5 aliens, the developers kept adding layers through GTA Online updates long after the base game was cold.
Remember the Gunrunning update?
Players discovered a secret mission involving a crashed alien ship and a stolen extraterrestrial egg. It wasn't just a random event; you had to complete 600 bunker supply runs before it would even have a chance of triggering. Six hundred. That is an absurd amount of grinding. Yet, the community did it. They documented it. They proved that the "Chiliad Mystery" wasn't just a relic of 2013, but a living, breathing part of the game's code that Rockstar was still tinkering with years later.
Then came the "The Diamond Casino & Resort" update. Players found a way to get a secret tattoo—a massive alien glyph on their back—by drinking a specific shot of Macbeth Whiskey at the bar during a thunderstorm. But there was a catch. You had to have already completed the alien egg mission from the bunker. It’s this kind of layered complexity that keeps the search alive. It’s not just about looking at a UFO; it’s about becoming part of the conspiracy.
The Los Santos Slasher and the UFO Abductions
Lately, things have gotten even weirder during the annual Halloween events. Rockstar stopped being subtle. Instead of just one ship hidden at the edge of the world, they started filling the Los Santos skyline with them. In recent years, players could actually get abducted.

If you walked into the light beams under the ships during the October events, you’d wake up in a basement—or even on a ship—wearing nothing but boxers branded with alien icons. It’s hilarious, sure, but it also confirmed something the "hunters" had been saying for a decade: the aliens are active participants in the world of San Andreas, not just static background art.
Facts vs. Fiction: What We Actually Know
Honestly, there is a lot of misinformation out there. You’ve probably seen the clickbait YouTube thumbnails with red arrows pointing at "Giant Alien Bosses" or "The Secret Alien City." Let’s get real for a second.
- The Jetpack is real, but not how we thought. The Chiliad Mural showed a jetpack. For years, people searched the mountain for it. It finally arrived in the "Doomsday Heist" update as the Thruster. It wasn't hidden in a cave; it was a purchasable vehicle.
- The Alien Egg is a prop. It exists in the game files and appears in the secret Gunrunning mission, but you can’t "hatch" it or use it to unlock a secret ending.
- The Frozen Alien is the start. In the very first mission of the game (the prologue in North Yankton), if you drive under the bridge before reaching the train tracks, there is an alien encased in the ice. This is the first confirmed Grand Theft Auto 5 alien encounter, and it's been there since day one.
The Omega Connection and the Space Docker
One of the weirdest NPCs in the game is Omega. He’s a paranoid hippie Michael meets in the desert who claims he was abducted and that his ship crashed. This kicks off the "Far Out" mission, where you have to find 50 spaceship parts scattered across the entire map.
It's a slog.
Your reward is the Space Docker, a modified buggy that looks like it was built in a garage using bits of a UFO. It makes weird sci-fi noises and has glowing blue lights. While it doesn't fly (much to everyone's disappointment), it’s the most direct link players have to the extraterrestrial presence in the story mode. Many theorists believe the Space Docker is the "key" to the Chiliad Mural, though no one has ever found a way to use it to trigger a "true" ending.

If you’re looking to jump into the mystery yourself, don't just wander around aimlessly. You need a plan.
First, get that 100% completion in Story Mode. It’s a rite of passage. Once you’ve done that, head to Mount Chiliad at 3 AM during a storm. If you don't want to wait for natural weather, you can use the weather cheat code to cycle through to rain. Seeing that holographic ship for the first time is a core memory for any GTA fan.
Second, if you’re playing GTA Online, keep an eye on the Halloween season. That’s when Rockstar goes all out. The UFO sightings usually progress through several stages, culminating in a massive blackout or city-wide events.
Finally, check out the "Epsilon Program" missions. While they are technically about a cult, their beliefs about "Kifflom" and extraterrestrial ancestors tie heavily into the broader alien lore. Some players believe the Epsilon tracts actually contain instructions for interacting with the UFOs, though the language is so intentionally dense and nonsensical that it’s hard to be sure.
The Grand Theft Auto 5 aliens mystery persists because Rockstar never gave us a straight answer. They gave us fragments. They gave us code that only triggers under impossible conditions. And in a world as cynical and grounded as Los Santos, that bit of "the truth is out there" keeps the world feeling much bigger than just a map of streets and skyscrapers.
Actionable Next Steps for Alien Hunters:
- Check your stats: Verify you have 100% completion in your "Brief" or "Stats" menu before attempting the Chiliad summit.
- Location Scouting: Visit the "UFO Camp" (the hippie habitat) in Sandy Shores. Look for the "Save Us" signs and the mural painted on the ground; it contains the same symbols found on the actual UFOs.
- Underwater Exploration: Grab a Submersible or a Kraken and head to the northernmost point of the map (Paleto Bay). The sunken UFO is located deep underwater—look for the distinct circular silhouette on your sonar if you’re using a vehicle that has it.
- Join the Community: If you want to get into the deep lore, the "Chiliad Mystery" subreddit is still the primary hub for debunking fakes and tracking new discoveries in the game files.
