It is commonplace these days for a game to have an update on release date, and Uncharted 4 is no exception.
Due to people getting hold of the game two weeks early in the UK it has been revealed that Uncharted 4 will have a 5GB day one update to unlock content such as network features. With this update it will unlock a bunch of bonus features. These include render modes, photo mode, singleplayer character skins, weapon selector, and gameplay modes among other features. Like all patches, there will be general fixes and improvements included.
Personally I don’t find a point in this update but that is because the added features don’t impair me playing through the single player campaign, but I suppose it will be important for those who don’t buy Uncharted for Uncharted.
