After four days, on December 9th Rockstar released an additional newswire post alongside a new trailer.
On December 5th, Rockstar announced through the Newswire the future opening of a new venue located under The Diamond Casino and Resort: The Music Locker. The next day, Rockstar released a teaser trailer on the Newswire along with the official title of the upcoming DLC and various information about its content.
The next week, on November 19th, a teaser was uploaded on the Rockstar Games twitter account and a dead, mutilated body with a briefcase appeared at random locations along the shoreline of Vespucci Beach. The first hint of this DLC came on the November 12th as a mysterious text message from Tom Connors and the addition of construction props by a service door on the north side of The Diamond Casino & Resort.
