Call of Duty: Modern Warfare 4’s campaign early access begins October 16, marking the first public preview of its Korean Peninsula-themed DMZ mode and new multiplayer features. Activision’s latest entry in the franchise will let players experience a new campaign set in the Demilitarized Zone (DMZ) between North and South Korea, alongside updated weapon crafting and PvP bounty systems. Here’s what’s confirmed about the release, how to access the beta, and what changes players can expect.
According to Activision’s official announcement, the early access phase will run through November 1, giving players a chance to test the campaign’s opening missions and the newly introduced DMZ mode before the full launch. The beta is exclusive to players who pre-ordered the game or own previous titles in the Modern Warfare series.
What sets this campaign apart is its focus on the Korean Peninsula, a setting that blends historical and fictional elements. While the game’s narrative avoids explicit political commentary, its inclusion of North Korean cities and military installations has drawn attention from global audiences. For players, this means a mix of tactical combat in urban environments and large-scale military operations—a departure from previous Modern Warfare campaigns.
What’s New in Call of Duty: Modern Warfare 4’s Early Access?
The early access phase will primarily highlight two major additions:
- DMZ Mode: A new multiplayer mode set in the Korean DMZ, featuring asymmetrical gameplay where players can engage in large-scale battles with unique objectives. According to GamesRadar’s breakdown, this mode will include elements like weapon crafting, base-building, and PvP bounty systems, allowing players to customize their loadouts and compete for rewards.
- Campaign Early Preview: Players will get access to the first three missions of the campaign, which follow a new protagonist as they navigate the Korean conflict. The missions are designed to showcase the game’s updated combat mechanics, including improved cover systems and dynamic environmental interactions.
Activision has emphasized that the early access period is a chance for players to provide feedback, with developers actively monitoring gameplay to refine the final release. “This is our first opportunity to let players experience the new direction we’re taking with Modern Warfare,” said a spokesperson for Activision.
How to Access the Early Access Beta
Eligibility for the early access beta is limited to:

- Players who pre-ordered Call of Duty: Modern Warfare 4 through any major retailer (PlayStation, Xbox, or PC).
- Owners of Call of Duty: Modern Warfare (2019), Modern Warfare II (2022), or Modern Warfare III (2023) who have an active subscription to Call of Duty: Warzone or Call of Duty Mobile.
Access will be granted automatically to qualifying players on October 16, with no additional steps required. The beta will run until November 1, after which the full campaign and multiplayer modes will be released to all players.
For those who miss the early access window, the full game is expected to launch in late November, with additional content drops planned through 2025.
What the DMZ Mode Adds to Modern Warfare 4
The DMZ mode is the most anticipated feature of the early access phase, offering a blend of large-scale warfare and player-driven objectives. According to Polygon’s analysis, the mode will include:

- Asymmetrical Gameplay: Players can choose to fight as either an elite squad or a larger group of soldiers, with different strategies and rewards.
- Weapon Crafting: A revamped system that lets players build custom weapons using scavenged parts, adding a layer of progression to multiplayer.
- PvP Bounties: A competitive system where players can earn rewards by completing objectives or eliminating enemies, similar to Warzone’s bounty mechanics.
- Dynamic Maps: The DMZ setting will feature destructible environments, allowing for creative tactical play.
While the mode draws inspiration from real-world geopolitical tensions, Activision has clarified that the game’s narrative is fictional and not intended to reflect actual events. “Our focus is on storytelling and gameplay innovation,” the spokesperson added.
Comparing Early Access to Past Modern Warfare Betas
This isn’t the first time Activision has offered early access to a Call of Duty title, but it marks a shift in how the franchise approaches beta testing. Previous entries, like Modern Warfare (2019) and Warzone, relied on closed beta events or limited-time trials. By contrast, Modern Warfare 4’s early access is more inclusive, targeting a broader audience of existing players.
A key difference is the emphasis on player feedback. Activision has stated that developer logs will be updated regularly during the beta, addressing bugs and balancing issues based on community input. “We’re treating this as a collaborative launch,” the spokesperson noted.
What Happens After Early Access?
Following the November 1 cutoff, the full campaign and multiplayer modes will be released to all players. Additional updates are expected in early 2025, including:
- A full season of multiplayer maps and game modes.
- New campaign missions expanding the Korean Peninsula storyline.
- Potential cross-play integration with Warzone and Call of Duty Mobile.
Activision has not confirmed a specific release window for these updates, but the company has historically delivered major content drops every few months. Players can expect official announcements closer to the dates.
