They went on to add: “Starting in Season One, player progression will be synchronized across Black Ops Cold War, Warzone, and Modern Warfare based on your current Season Level in Black Ops Cold War.

“All previous unlocks from Black Ops Cold War and Modern Warfare (weapons, Perks, Scorestreaks, or Killstreaks) will remain unlocked.”
