The PS4 version of Borderlands: The Handsome Collection will require a rather large 8.31GB patch on day one.
The reason the update is so big is because the update includes the latest DLC, Claptastic Voyage, which was not completed in time to be included on the disc so will be a free download instead. There has been no information on the size of the patch for the Xbox One version of the game at the time of writing.
The patch will also fix some bug issues as well as make some tweaks to improve the gameplay of Borderlands 2 and Borderlands: The Pre-Sequel, the full list can be viewed here.
Gearbox have strongly recommended, due to the amount of content and changes, that players download the patch before playing the game. If you have pre-ordered the digital version of the game, the update should automatically download with the title.
Borderlands: The Handsome Collection releases on Xbox One and PS4 this Friday.
UPDATE: It’ll be even worse if you’re on the Xbox side of things, with the patch for Xbox One being a mighty 16GB in size.
