Halloween arrived in Grand Theft Auto Online some time ago, but the horrors appear to have seriously escalated in the multiplayer live service game. UFOs began showing up in-game on October 15, first appearing at remote locations and then disappearing if Grand Theft Auto Online players got too near. The day of Halloween has brought this alien incursion to its peak, however. There are now hovering UFOs across Los Santos in San Andreas. What these UFOs' goals might be in Grand Theft Auto Online remains a huge mystery.
