This page contains information on the various alien and UFO sightings that can be experienced around San Andreas in Grand Theft Auto 5 and GTA Online.
The latest alien encounter was recently discovered by GTA super-sleuths Chilliad Mystery Gurus. In the Gunrunning update, one of the supply missions sends players recovering an alien egg from a crashed UFO in the Zancudo riverbed.
How to Unlock the Alien Mission
The mission is a supply run for your weapons manufacturing bunker, so it is launched from the Disruption Logistics laptop in your bunker. However, according to the CMG team, the requirements for receiving this assignment from Agent 14 are as follows:
- Players must have completed at least 600 weapons sales missions.
- Launch a Steal Supplies mission between the in-game hours of 21:00 (9:00pm) – 23:00 (11:00pm).
After achieving 100% game completion in the single-player story mode of GTA 5, players will be able to see UFOs hovering about Los Santos and Blaine County at certain times of day or under specific weather conditions.
The Ongoing Mystery
Amidst a hodgepodge of GTA 5 UFO appearances, Alien sightings, Flying Saucers, strange codes, and jetpack rumors, a tantalizing unsolved mystery continues to frustrate players.
What Do These Symbols Mean?
Explorers have found spacecraft hovering over mountaintops and concealed in the skies high above significant landmarks. After meeting Omega in the desert, a series of glowing, pulsing Spaceship Parts appear scattered throughout San Andreas. Tracking them down leads to the creation of a tiny spacecraft, and unlocking of the Space Docker.
Delvers have reportedly made some progress in the meta-game, discovering Jetpack References in Source Code, but the mystery remains perplexing and unsolved. Is there something still hidden in the game waiting to be discovered by a world full of searchers, or does an answer await in DLC?
The Truth is Out There, Somewhere
For over a year, dedicated GTA 5 players have combed the map of San Andreas amassing clues, searching for anything which might explain the meaning of the glyphs. Online communities have grown up around the mystery, with members swapping notes, exchanging discoveries, and systematically testing, substantiating, and debunking theories.
The Beginning of the Search
A cryptic painting on the wall of the Cable Car station atop Mt. Chiliad was one of the earliest sources of intrigue for GTA conspiracy-hunters.The main map is remarkably similar to the shaft and chamber layout of a pyramid, suggesting the possible existence of a subterranean dungeon. Also scattered around the image are a number of smaller markers. While the meaning of many of the symbols within have been encrypted, the large icons of cracking egg, a spaceship, and a humanoid form remain an intriguing puzzlement.
The symbol matches the UFO depicted in the Cable Car station painting. On the back of the platform it reads “Come back when your story is complete.”
The carefully hidden painting beneath the platform atop Chiliad’s highest point is the sighting point for a well-documented postgame Flying Saucer appearance, which takes place late at night during thunderstorms. Other symbols likely indicate other known Glyphs spaced around the mountain. The evidence strongly suggests a relationship between the mountain and the mysterious uninterpreted Glyphs.
Working together, members of the Reddit community have discovered methods for locating interiors to structures all over the GTA map…including a flying saucer interior. One of these chambers might prove to be a secret area or a teleporter leading to hidden content. Some interiors have been explored and proved to be set pieces for cut scenes, but others remain to be examined.
The image above, created by Reddit’s TMBSTruth, indicates some of these locations.
Meanwhile, other users have drawn a connection between the fountain outside Maze Bank and the egg. Look carefully for the shape and the crack.
Reddit user Huge_Dabs notes a possible connection to Sacred Geometry indicating a hidden egg clue as well: Note the similarity in the Egg of Life pattern to the fountain’s center.
Could something be hidden in or near the Maze Bank building?
Other Theories and Connections
Dedicated players have used exploits to spawn Vehicles under the map. Using their new-found mobility, they have discovered hidden FIB textures beneath the Mt. Chiliad platform and strange objects beneath Ft. Zancudo. 
Some players speculate that the Mt. Chiliad Map should be laid over the GTA 5 pack-in paper map to reveal a number of significant locations. Current efforts center around centering the map above the northward edge of the island, though this produces no discernible explanation for the three main Glyphs.
An alternate theory (image below) involves lining up the eye at the top of the mountain (red dot) with the glyphs on the the side of the mountain (green dots) leaving one half faded glyph (green circle).

Glyphs line up as per the image below:
While intriguing, these theories fail to address the purpose of the connecting lines between Glyphs, as well as the three large symbols. Source code for the 1.12 update reportedly includes Jet Pack references. As reported, the new code reads:
p_SPA_Jetpack<br />CTaskJetpack<br />TASK_JETPACK<br />DRIVEBY_JETPACK // Setting it so you can shoot from the JETPACK just like parachute<br />.?AUTunables@CTaskJetpack@@<br />?AVCTaskMotionJetpack@@<br />.?AVCJetpack@@<br />.?AVCTaskJetpack@@<br />.?AVCGadgetJetpack@@ // the actual jetpack just like parachute.<br />TASK_JETPACK(int unk);<br />XBL Toothpik found possible skis .data:838E1118 00000012 C .?AVCGadgetSkis@@<br />.rdata:820571DC 0000000D C START_SKIING<br />.rdata:820571D4 00000007 C SKIING<br />.rdata:820571C4 0000000E C FINISH_SKIING
Alien Flying Saucers
To date 4 confirmed UFOs have been located in GTA 5. Details on each are available at UFOs. Most pertinent to the search is the presence of a UFO directly over Mt. Chiliad, appearing in the rain at 3 AM after 100% completion.
The Search for Underground Tunnels at Mt Chilliad
Recent reports of players using clipping glitches to gain access to the inside of the mountain to show tunnels have mostly been dismissed as known and already accessible tunnels:
- The Road Tunnel joining Paleto Bay to the Alamo Sea
- The Rail Tunnel joining Paleto Bay to the Alamo Sea
- The Road Tunnel that passes under the runways at Fort Zancudo
Though the hunt still continues as tunnels are not made visible until in close proximity. Current searches are revolving around the Saw Mill drain grates.
After the release of the GTA Content Creator, players utilizing the tool discovered that a sealed elevator door in Ft. Zancudo can in fact be opened. The door has often been a source of speculation as a possible entry point to an underground area related to the Mt. Chiliad map. Unfortunately, the elevator inside is currently inoperable.
The Jetpack Connection
Online communities of UFO hunters have focused largely on a resemblance of the humanoid glyph to a person riding a jetpack. Many people believe that unlocking the riddle of Mt. Chiliad will unlock access to this GTA unicorn item.
The UFO hippie camp near Sandy Shores is ringed with a trail of Alien script. Some players believe the script might contain a decipherable code, others believe it to have ties to Yoga positions which are themed throughout the camp.
The breaks between examples below are limited by video capture capabilities, not by any distinctive breaks in the text. Viewed left to right from the outside of the ring, the code reads:
Possible Alien Code Part 1
Possible Alien Code Part 2
Possible Alien Code Part 3
Possible Alien Code Part 4
Possible Alien Code Part 5
Possible Alien Code Part 6
Possible Alien Code Part 7
Possible Alien Code Part 8
Possible Alien Code Part 9
It’s also possible that the code reads from the inside of the ring, in which case the images would be flipped and the order reversed.
Other GTA 5 Alien Stuff
These flying saucers aren’t the first hint of extra-terrestrial life in GTA 5. The GTA 5 Special Edition map includes a UFO part location revealed by exposure to black light.
Alien Glyphs are concealed throughout the map, including drawings on Mt. Chiliad, near the Altruist Camp, and at the Hippie Camp.
Aliens also make cameo appearances frozen in ice in the Prologue Mission and wandering the lots of the movie studio.
Aliens are also seen several times during hallucinations by Michael and Trevor. What does this mean? Is there a secret cavern beneath Chiliad? If so, how does one access it? Or is it a deliberate red herring? When we know, you’ll know, gentle readers. Check back for updates, and add your own discoveries to the GTA 5 Wiki.
