Apparently, Rockstar has already begun working with partners and bloggers as part of an advertising campaign to promote Grand Theft Auto 6, having started sending out letters with the date of the first showing of the upcoming sandbox.
This letter with the title “ Introducing the next chapter ” was shared by tester nima02l, who works with various companies on a number of games.
nima02l intentionally hid the main details of the letter for fear of Rockstar’s legal department, but the accessible part of the text shows what exactly it contains.
Rockstar itself has not yet shared official information about the timing of the game's release.
