We previously reported that noted R-Star insider Tez2 posted something at gtaforum about Ufos coming to GTAOL in October, and hinted that it might be linked to the GTA6 Easter egg.
Ufos are starting to arrive in the world of GTAOL. And it will be an ongoing event, with different types of Ufos appearing one after another throughout the month.
The ufo Landing campaign in GTAOL will end on October 21. It has been rumored that a special invisible ufo will appear on the day the event ends, bringing GTA6 promotional information to players, and insiders Tez2 have confirmed that there will indeed be a hidden ufo on that day.
Coincidentally, October 21st is also the 25th anniversary of the GTA series, so we'll see.
