Myths & Mavericks pack will add new multiplayer content in September.
The Myths & Mavericks Bonus Pack, released in September, will allow users to play as Landon Ricketts, among other familiar faces. It sounds as if the new multiplayer locations will all be culled from the existing game world, however.
The update will also allow players of Overrun Mode in the Undead Nightmare expansion to play using the original settings, something that had been in demand.
Rockstar described the Myths & Mavericks pack as "a show of appreciation for the awesome long-term support for the game's multiplayer modes since its release in 2010."
