Secret Fort Zancudo Lab: GTA Online UFO Event Guide

The GTA Online Secret Fort Zancudo Lab is a research lab inside the secret Fort Zancudo Bunker, and the way in is a UFO abduction during the Sightseeing Halloween event. From the 2023 event onward, each Stage 3 UFO abduction has a 25% chance of sending you there. In 2024 and 2025, opening a crate in the lab gives a reward.

How to reach the secret Fort Zancudo lab

  1. Play during Stage 3, the last part of the event, when UFOs arrive at 7:30 PM and stay until 6:30 AM.
  2. Walk into the beam of light of a UFO on foot. Some beams can only be reached from a rooftop.
  3. You are abducted and wake up in a new spot in the UFO Boxer Shorts. One time in four, that spot is the lab inside the secret Fort Zancudo Bunker.
  4. If you wake up elsewhere, you can try again. The abduction can be repeated, although your character is killed each time.

The full process of getting taken is described in the UFO abduction guide.
