As expected, it was a false information created through mods.

It's time to temper tempers. If yesterday we told you that there had been a series of images around GTA Online that seemed to augur the launch of GTA VI . Already then we warned you that it was most likely that it was something false as a result of a hack and now it has been Rockstar who has denied it.

"It is a fraud made with the use of mods, and is not an official message or any type of announcement from Rockstar Games, " they comment from the official Twitter account of support of the company that created the GTA saga .

We already told you yesterday that it was not very plausible that GTA 6 was launched in 2019, due to the usual rhythm of Rockstar's own releases that are already selling their much anticipated Red Dead Redemption 2 this year .
