About

Published August 20, 2026 · Category: Games

Overview

You can't regularly queue up for combat until October, but a series of Call of Duty: Modern Warfare 4 betas are a chance to try one upcoming campaign mission and several multiplayer maps before launch. Trying to decipher what happens when and how to register is super convoluted, so here's an info drop on the MW4 beta dates and what you'll need to get started.

Call of Duty MW4 beta dates

You've got two options for jumping into the MW4 beta: If you pre-order the game you can participate in the first round (early access beta), or you can wait and play for free in the second (open beta).

Some players need a MW4 beta code to participate in the early access weekend starting on August 21, but it all depends on how you've pre-ordered. The second period on August 28 doesn't require a purchase; it's open to anyone on Steam, Battle.net, or consoles.

The MW4 open beta weekend on August 28 does not require a pre-order or beta code to participate. Anyone can download the open beta build on any platform.

What you need to know about the early access beta codes

  • You can redeem MW4 beta codes through the official COD site
  • Only players who pre-order physical editions or digital copies (through other retailers) of MW4 will need to redeem a beta code
  • Anyone who pre-orders through the in-game store or a platform store (like Steam, PSN, etc) receives automatic access and does not need a beta code

How do I get a MW4 beta code for the early access dates?

Pre-orders are the only way to guarantee you get into the early access beta, but I've spotted MW4 beta code giveaways around places like Reddit and most social platforms. The Call of Duty: Next Showcase also notes it's hosting code giveaways—that starts at 9 am PDT on August 21, and you can watch it on YouTube.

The maps and modes available in both beta weekends

Most maps and modes are available in both MW4 betas, but features like Combat Outpost aren't available until the second weekend. A couple of maps are also limited to just one weekend, so I've put together those key differences in a table for reference
