How to Register for the COD MW4 Early Access Beta

The steps are slightly different depending on whether you pre-order the digital or physical version of the game.

Method 1: Digital Pre-order

If you pre-order the digital version of the game, you actually don’t have to sign up anywhere.

• Go to the digital version of the game store.
• Pre-order Call of Duty: Modern Warfare 4.
• Wait for the beta client pre-load to be available.
• Download the beta client.
• Run the client on August 21 when servers launch.

Method 2: Physical Pre-Order

• Pre-order the physical version at one of the authorized retailers.
• Obtain the beta key from the retailer.
• Use this key on the official Activision beta redemption site.
• Choose the platform where you intend to play the game.
• You will get the platform-specific download key before the start of the beta.

What Can Players Expect During the Beta?

The multiplayer beta lets players try the Kill Block map, explore new maps revealed at Call of Duty NEXT, experience gameplay updates and weapon balancing, watch developer showcases, and provide feedback before the game's official launch.

With the COD MW4 beta release date now confirmed, players can join the Early Access Beta by pre-ordering the digital edition or redeeming a beta code with a physical copy. Those who don't pre-order can still play during the Open Beta a week later. The beta will also give players an early look at the game's multiplayer before its official launch.
