Pre-orders of all editions grant "early" access to the open multiplayer beta. The Vault Edition grants access to a "Red Team 141" operator pack, a "FJX Cinder Weapon Vault" pack, plus access to the Battle Pass of a Season for Modern Warfare II (dependent on the time of purchase), and double XP tokens.
