The Early Access Beta runs from August 21 at 2 PM ET / 11 AM PT to August 25 at 1 PM ET / 10 AM PT. It’s available on PS5, Xbox Series X/S, and PC, and access requires a pre-order code or Discord Nitro. Preloading for this phase already opened on August 20.

2 Ways to Get a Modern Warfare 4 Early Access Code

To join the Early Access phase without waiting for the Open Beta, players can secure a code through two main methods:

Pre-Order Modern Warfare 4

Digital Pre-orders: Buying digitally via platform stores (PlayStation Store, Xbox Store, Steam, or Battle.net) automatically grants access—no registration code required.
Physical Pre-orders: Retail purchases include a digital code on the receipt or via email, which must be redeemed on the official Call of Duty website.

Claim via Discord Nitro

Active Discord Nitro subscribers ($9.99/month) can claim an Early Access code directly without pre-ordering the game:

Open Discord and navigate to Nitro Home.
Scroll to the Nitro Rewards tab and select the Call of Duty: Modern Warfare 4 reward.
Copy the code and redeem it on Activision’s beta page.

Modern Warfare 4 PC System Requirements

To ensure smooth performance during the multiplayer beta, make sure your rig meets or exceeds these official PC specs:

PC Hardware Requirements

For the minimum requirements, you’ll need Windows 10 64-bit with the latest updates, an Intel Core i5-8400 or AMD Ryzen 5 1600 CPU, 12 GB of RAM, and a NVIDIA GTX 1060, AMD RX 470, or Intel Arc A580 GPU with 3 GB VRAM. An SSD is required for storage.

For the recommended specs, upgrade to Windows 11 64-bit with the latest updates, an Intel Core i7-8700 or AMD Ryzen 5 3600 CPU, 16 GB of RAM, and a NVIDIA RTX 3060 Ti, AMD RX 6700 XT, or Intel Arc B580 GPU with 8 GB VRAM. SSD storage is still required.

Basically, minimum gets you in the game, but recommended will give you much smoother performance.
