Halo 5: Guardians will not only require a massive 46GB installation on the Xbox One, chewing up a huge 13% of your Xbox One HDD, but it will require a rather large 9GB day one patch.
343 Industries boss Josh Holmes announced the news through Twitter, with the 9GB patch for Halo 5 filled with multiplayer content. Holmes added that the 9GB patch includes map content for Halo 5, but the question remains: why isn't this data on the Blu-ray for Halo 5: Guardians - were 343 Industries not finished with the game when it went gold or what?
Not only will there be a 9GB day one patch, but 343 Industries will be pushing out some post-launch content. The post-launch content for Halo 5 will include 18 new maps that will join the 21 maps included in the game at launch, as well as a new Forge game mode that will launch in December.
