Fans of Call of Duty do not have to wait for the full launch to experience the latest story. Call of Duty: Modern Warfare 4 offers Campaign Early Access, allowing eligible players to begin the single-player story before the official release. The early access period began on October 16, 2026, giving players a full week to explore the campaign before launch day.

If you want to know how to play the Modern Warfare 4 campaign early, here is everything you need to know about pre-orders, supported platforms, installation, and the content available during this period.
How to Get Early Access to the Campaign
The main requirement is owning an eligible digital edition of Call of Duty: Modern Warfare 4. Activision has confirmed that players who digitally pre-order or purchase the game can access the complete campaign during the early access period.
You can qualify by purchasing either of these editions:
- Standard Digital Edition: Includes the base game and campaign early access.
- Vault Edition: Includes the game, campaign early access, and additional bonus content.
You do not need to purchase the more expensive Vault Edition just to play the campaign early. The Standard Digital Edition also provides access to the early campaign.
Supported Platforms for Early Access
Campaign Early Access is available across the following platforms:
- PlayStation 5
- Xbox Series X|S
- Xbox on PC
- Steam
- Battle.net
- Nintendo Switch 2, subject to platform availability
Make sure you purchase the game through the correct digital store for your platform. If you own multiple gaming systems, check which platform your purchase is linked to before downloading the game.
How to Download and Start the Campaign
Once you have purchased an eligible edition, follow these steps to start playing.
Step 1: Purchase the Game
Open your platform’s digital storefront and purchase the Standard Digital Edition or Vault Edition of Call of Duty: Modern Warfare 4. If you already pre-ordered the game digitally, you should not need to purchase it again.
Step 2: Download the Game
Visit your game library and locate Modern Warfare 4. Start the download if it is available. If the game uses a shared launcher or content management system, make sure the campaign files are installed.
Keep enough free storage available for the game and its updates. Download sizes can vary depending on your platform and installed content.
Step 3: Check for Updates
Before launching the game, install any required updates. Restart the game or launcher if the campaign does not appear immediately. You may also need to sign in to your platform account and connect to the internet to verify your purchase.
Step 4: Select Campaign
Launch Modern Warfare 4 and open the Campaign section from the main menu. Select the available campaign option, choose your preferred difficulty, and begin playing.
What Can You Play During Early Access?
The early access period includes the full single-player campaign rather than a limited demo. The story features 16 missions set across the Korean Peninsula, Paris, New York, and Mumbai.
Players take the role of Private Park Hyun Jun, a South Korean soldier caught in a major invasion. Meanwhile, John Price pursues the people responsible for the growing international conflict.
Campaign completion rewards are also available. These rewards can be used in Multiplayer and DMZ when the relevant modes launch, giving players an opportunity to unlock additional content before the full release.
When Does Modern Warfare 4 Release Fully?
Call of Duty: Modern Warfare 4 is scheduled for its full release on October 23, 2026. Campaign Early Access began on October 16, while DMZ Early Access is scheduled to begin on October 20.
This means players who qualify for early access can experience the story first and then move into DMZ before the full launch.
Can You Play the Campaign Early Without Pre-Ordering?
The full early access campaign requires an eligible digital purchase. Players who have not purchased the game cannot rely on early access being available for free.
A physical purchase may not provide the same early access benefit, so check the terms associated with your specific edition before buying.
