They are also usually unannounced and generally consist of nothing more than minor tweaks to the game.However, this update contains a bit more than that. The 'Sightseeing' event hinted at in this update appears to be linked to the game's Halloween preparations for 2021. Players in GTA Online can expect a 2021 Halloween update next week, possibly on October 28, 2021. In the midst of all the hype, data miners have also discovered evidence of Rockstar's preparations for the upcoming Halloween events.One of these is a car that is reenacting a scene from John Carpenter's popular horror film Christine. As of now, the full scope of the changes that Rockstar is bringing to GTA Online with the Halloween update is unknown. However, players will surely be informed of all upcoming events quite soon.
