Pre-Order If You Want to Play Call of Duty: Vanguard ASAP
If you want to play Call of Duty: Vanguard the second it's released for your platform, you'll want to pre-order a digital copy.
If you buy a digital copy of the game you'll be able to pre-load it onto your platform of choice ahead of the game's release date in November.
Pre-loading the game files ahead of time will allow you to jump right in when the game unlocks on November 5th. Those of you in western time zones will be able to play starting on November 4th.
If you buy a physical copy you won't get your delivery until the morning, afternoon, or night of November 5th. For some of you, that might not be ideal.
