Halo 5: Guardians will have a Massive Day One Patch

343 Industries has revealed just how large the Day One patch for Halo 5: Guardians is. That patch is 9GB, and you’re going to need it if you want to play any of the multiplayer.

Studio Head Josh Holmes revealed the file size on Twitter, confirming it contains large amounts of multiplayer data. In particular, the patch contains a ton of map content.

Halo has always been known for having excellent multiplayer, and 343 Industries hopes to continue that trend with Halo 5: Guardians. There are two new modes in Halo 5, Warzone and Arena. Warzone is a large-scale battlefield where Red and Blue teams battle for control of outposts. Arena is Halo 5’s eSports mode where two teams of four battle to complete objectives. Traditional modes will return just in case Warzone and Arena don’t fit your playstyle.

Halo 5: Guardians is out October 27 exclusively on Xbox One.
