Can You Use Cold War Weapons in Warzone?
All weapons unlocked in Modern Warfare, along with all weapons that will be unlocked in Black Ops Cold War, should be available in Warzone. The developer's plan for Warzone is to include all Primary and Secondary weapons available throughout the entirety of Black Ops Cold War.
However, players will not be able to take Modern Warfare weapons into Black Ops Cold War, and vice versa. Only Warzone will be the weapon's melting pot.
Players will be able to distinguish between Black Ops Cold War and Modern Warfare's weapons by checking on weapon's menu tile and looking for the logo. When a player unlocks a weapon in Black Ops Cold War, it should immediately appear in Warzone.
