Call of Duty: Modern Warfare 4 is opening its next phase early, and DMZ players are first in line. According to Activision’s official Call of Duty blog, DMZ Early Access in Modern Warfare 4 begins October 20, 2026, sitting just ahead of the full game launch on October 23. It is the latest in a string of staggered access windows designed to let pre-order players jump in before the wider release.
The timing is confirmed on both sides of the aisle. The official Steam store page for Modern Warfare 4 (App 4435490) lists DMZ Early Access starting October 20 as a pre-purchase bonus, alongside a release date of 22 Oct, 2026 and Advance Access that is currently on now. For Steam players who have already pre-purchased, that means a short wait between the campaign window and the DMZ drop.
Campaign Early Access has already been live since October 16 for digital pre-orders on Steam and other platforms, giving early buyers a head start on the story before multiplayer and DMZ arrive. Activision notes that campaign completion rewards carry over to Multiplayer and DMZ at launch, so time spent in the campaign is not wasted once the rest of the package unlocks.
The progression hand-off matters most for DMZ, the extraction mode that has built its own dedicated audience. Players who clear campaign objectives will carry tangible rewards straight into their first raids, smoothing the ramp into a mode that is normally about starting cold, looting up, and getting out alive. It is a small but meaningful quality-of-life touch for anyone planning to split time between the three pillars of the game.
On Steam, the page reflects the same structure the blog describes: a pre-purchase path into DMZ Early Access on October 20, an Advance Access period already running, and a full release dated later that week. The slight date gap between platforms is worth noting, but the DMZ Early Access start of October 20 is consistent across the official blog and the Steam listing.
For Modern Warfare 4 owners, the week ahead is straightforward. Pre-purchase bonuses unlock DMZ Early Access on October 20, campaign progress keeps feeding the other modes, and the full game launches October 23. Keep an eye on the official Call of Duty blog and the Steam store page for final rollout details as the launch window arrives.
