Multiplayer Operators can expect to choose a Field Upgrade for their matches, while Battle Royale Operators locate these items during a game. There are 18 Killstreaks to choose from and unlock:
New Players: Unlock Killstreaks as you level up through the ranks or unlock in the Arsenal Store.
MWIII/Call of Duty: Warzone/Call of Duty: WZM Cross-Progression: Any of the 18 Killstreaks that you’ve unlocked already will Carry Forward to Call of Duty: Warzone Mobile at launch, including any Skins. Killstreaks that are unavailable in Call of Duty: Warzone Mobile will not Carry Forward.
