July 4 is Independence Day in America, and to commemorate the occasion, Rockstar will be making special Independence Day DLC for GTA: Online available for PS4, Xbox One, and PC owners. The DLC will include a new racer Vagner, new skins, new weapons, and new T-shirts.
You don’t have to download anything, either, because the content has been made available from the server-side- just log in, and you should be able to access all the new content. You can also go to AmmuNation, where you will get a fireworks launcher that should let you celebrate Independence Day as it is meant to be celebrated within GTA: Online.
GTA: Online as well as GTA5 are available for Xbox 360, Xbox One, PS3, PS4, and PC; however, the last gen versions are no longer supported with updates and new content, so you will not be able to access this Independence Day DLC on them.
