As the launch window for Call of Duty: Modern Warfare 4 rapidly approaches, Activision has begun outlining the rollout schedule for the latest installment in its powerhouse military shooter franchise. Players eager to jump back into the tactical action can look forward to a tiered release structure, with digital preorders granting early access to both the single-player campaign and the highly anticipated return of the fan-favorite DMZ extraction mode ahead of the game’s global launch later this month.
According to the official release schedule, players who choose to preorder Call of Duty: Modern Warfare 4 digitally will gain early entry into the game’s narrative campaign starting on October 16. This early access period gives story-driven fans a head start on the cinematic single-player experience before multiplayer servers and other wide-scale operational modes open up. Following the campaign early access, the tactical extraction experience known as DMZ will become available to eligible players starting on October 20, marking a significant revival for a mode that has commanded a passionate community following since its previous iterations.
While Activision has confirmed the calendar dates for these early access windows, specific minute-by-minute rollout times for the October 16 campaign launch have not yet been officially detailed by the publisher. Similarly, the exact hour for the DMZ early access unlock on October 20 remains officially unannounced, though industry analysts and community trackers have pointed to a potential 10:00 AM Pacific Time rollout—corresponding to 1:00 PM Eastern Time and 6:00 British Summer Time—based on historical release patterns for the franchise.

For players opting for standard physical editions or those who choose not to preorder, the full, unadulterated global release of Call of Duty: Modern Warfare 4 is locked in for October 23 at midnight local time across all participating regions and platforms.
To help alleviate network congestion on launch day and ensure players can dive straight into the action without waiting for massive downloads, Activision has already activated the PC preload phase. Players on PC can currently download the game files ahead of time. However, those preparing their systems will need to clear a substantial amount of space on their hard drives. Call of Duty: Modern Warfare 4 demands a hefty 115GB of available storage space, reflecting the expansive scope, detailed graphical fidelity, and sheer volume of assets packed into the modern title. Comprehensive system requirements detailing the necessary graphics cards, processors, and memory configurations needed to run the game smoothly are currently available for review directly on the official Steam store page.
As the community counts down the days toward the initial early access phases, the DMZ rollout, and the full global release on October 23, further updates regarding precise unlock times and server status announcements are expected to be provided by Activision as they become finalized.
