The Call of Duty series is known as one of the worst sinners when it comes to storage, sometimes hogging almost 200 gigabytes for a full installation.

One of the reasons Vanguard needs less storage space than it recent predecessor is "due to new on-demand texture streaming tech". We assume this means the game needs to be connected at all times for this to work properly, but that pure speculation on our behalf. We're also promised that PC info is "coming soon".
