Xbox Series X/S: 61 GB download | 61 GB required space. Xbox One: 56.6 GB download | 56.6 GB required space.

Unlike some other Call of Duty titles, namely Warzone and Black Ops Cold War, Vanguard does not ask for a lot in terms of storage space  around 50 GB including the campaign mode, as I said before. And, if you are a fan of multiplayer, you will not be disappointed since it also supports crossplay.
