Modern Warfare 4 Launch Timeline: Preload, Early Access and What DMZ Offers

Modern Warfare 4 is days away, and Activision has laid out a staggered rollout that gives pre-order buyers several ways to start early. If you plan to jump in on day one of the Call of Duty season, here is how the timeline works and what to expect from the new DMZ mode.

The key dates

Preloading opens on 14 October at 9pm PT, which is 5am BST on 15 October (6am CEST). It applies to PS5, Xbox Series X|S, PC through Steam, Battle.net and Xbox, and Nintendo Switch 2. Campaign Early Access follows on 16 October, and DMZ Early Access starts on 20 October, in both cases for players who pre-ordered or pre-purchased digitally. The full worldwide launch is scheduled for 23 October 2026.

Plan your storage

Reported download sizes vary a lot by platform: roughly 117 GB on PS5, about 194 GB on Xbox Series X|S, around 115–124 GB on PC and between 77 and 85 GB on Switch 2. These are estimates and can change. Players can choose which components to install during preload, including Warzone, and PS5 owners who want control over what downloads may want to switch off automatic downloads first.

What DMZ brings

DMZ is a premium mode in this release rather than a free-to-play add-on. Its main map, Hajin, is built around 13 major points of interest, plus smaller locations such as clinics, gas stations and exfil points. Between runs, players return to the Forward Operating Base, a hub for operators, stash management, orders, gunsmithing and progression up to level 70.

The loop is classic extraction: loot containers for gear and materials, deal with AI enemies and other players, then reach an exfil before the radiation storm tightens. Hajin is patrolled by several tiers of soldiers, drones, helicopters and convoys, and each area carries a threat rating. Filling the kill count triggers a hunt squad, so stealth, suppressed weapons and careful movement matter as much as raw aim.

Why it matters beyond the casual crowd

A new Call of Duty always reshapes the competitive scene, too. Balance changes, weapon meta and movement rules decide which line-ups look strong, and anyone following the esports bookmakers market will want to see how the first events play out before trusting early odds. For now, the practical advice is simple: preload early, check your platform’s download settings and decide whether early access is worth a pre-order.
