Infinity Ward's upcoming blockbuster, Call of Duty: Modern Warfare 4, is already shaping up to be one of the biggest releases of 2026. Following the official campaign trailer reveal last week, attention has now shifted to the multiplayer component — and a fresh wave of leaks has sent the community into overdrive.
Beta Dates Surface
According to multiple industry insiders, including prominent Call of Duty leaker TheGhostOfMW, Modern Warfare 4's multiplayer beta will run in two phases. An early access weekend for PlayStation pre-order customers is said to begin on July 10, followed by a cross-play open beta from July 17-20 across all platforms including PC, Xbox, and PlayStation.
If the leak holds true, this would give Infinity Ward roughly four months between the beta and the game's November 6 launch date — ample time to incorporate community feedback and fine-tune weapon balancing based on player data.
Classic Maps Making a Comeback
Perhaps the most exciting rumor to emerge from the leaks is the return of iconic Modern Warfare maps. Sources claim that the base game will ship with at least three remastered classics: "Rust" from Modern Warfare 2 (2009) — widely considered one of the greatest Call of Duty maps ever designed — "Highrise" and "Terminal." These maps will be rebuilt using the new IW 10.0 engine, featuring ray-traced reflections, dynamic weather, and enhanced destructible elements while preserving the flow and layout that made them legendary.
Alongside these returning fan favorites, Infinity Ward is reportedly preparing 12 brand-new maps at launch, with additional post-launch content planned through seasonal updates. The leaked documents also suggest a return to the traditional "Pick 10" Create-a-Class system that many fans have been clamoring for, albeit with modern twists to accommodate the new omnidirectional movement mechanics.
Warzone: Nexus Integration
As previously reported, MW4 will integrate seamlessly with Warzone: Nexus, the unified battle royale experience that bridges multiple Call of Duty titles. The new IW 10.0 engine's modular weapon physics system will allow for unprecedented gunplay consistency across both the core multiplayer and Warzone experiences — a technical achievement that Infinity Ward has been developing for years.
Infinity Ward has not officially confirmed the beta dates or classic map lineup. However, given the track record of the sources involved, there is strong reason to believe that the leaks are accurate. We'll bring you more details as they emerge.
