Rockstar have already mentioned in the past that they have plans for new DLC content for Grand Theft Auto 5, however unlike previous GTA games, the developer has solely focused on releasing new free content for the online portion of the game since it's release.
However, despite this, Rockstar still have been quietly working out their plans for new singleplayer DLC for Grand Theft Auto 5, and thanks to new rumors, we may now know a fair amount about the new upcoming content.
Allegedly, Grand Theft Auto 5 will soon be receiving a brand new DLC pack that will include some kind of zombie related content. The rumors surrounding this report are very loosely based on some leaked code found within Grand Theft Auto 5, so we'd better take this with a very large grain of salt.
However, we've also been hearing a lot about a set of casino based DLC content from a few various sources, some of which suggest that the new DLC pack will include multiple casinos, three mini games 12 new assassination missions, as well as other missions for Trevor, the IAA and other characters.
So, can we expect a brand new zombie themed DLC pack alongside a casino DLC pack for GTA 5 in the near future? Honestly, we have no clue, but it could be possible. Hopefully we'll hear something official from Rockstar as soon as the PS4 and Xbox One versions of the game are released.
