Grand Theft Auto V is a game with many paranormal and alien secrets, and more continue to come to its Online mode over time. A group of dataminers have found evidence of a new alien spacecraft in the game, and activated a mission that has been added to the game's files but is not properly accessible yet.

Kotaku has reported on the Fort Zancudo UFO Business Battle, which was uncovered by The Game File Gurus. The mission, which quietly slipped into the game's code alongside the Summer Special update, involves breaking into the hanger the UFO is being stored in and stealing spaceship parts.

You can watch the mission--which likely isn't in its final form--in the video from The Game File Gurus below.
