GTA IV owners who have the game on Xbox One might have received an update on their console. This had a fairly large size and lacked any patch notes.
It was first thought that this might be an update to patch the game and support native 4K resolution and other improvements that are usually featured for the Xbox One X. This didn’t turn out to be the case sadly, as there was no visual improvement made to the game.
The download size of this new GTA IV update was also rather large. It required close to 7 GB of update data to be downloaded on Xbox One. This is unusual for a backward-compatible game which usually gets small updates, even the ones that add support for the Xbox One X.
It has been discovered now that this update will patch back the songs that were removed by Rockstar Games in another update released in April 2018. This discovery was made by a fan account who shared it on Twitter.
Apparently, these songs had their license expire on April 2018, in time for the 10th anniversary of GTA IV. As a result, Rockstar Games had them removed from Grand Theft Auto IV until they were able to get the license to put them back in the game. They are quite happy with the success of Red Dead Redemption 2 and are currently working on their next project as per the reports.
