What is Call of Duty: Modern Warfare 4?
Call of Duty: Modern Warfare 4, or MW4, is an Infinity Ward shooter with a story campaign, competitive multiplayer and the DMZ extraction mode. Its campaign follows a South Korean squad amid a widening conflict while Captain Price pursues a separate mission. Players planning their first session should distinguish the full game from the earlier Campaign and DMZ access periods: they open on different dates and require an eligible digital preorder. The published console lineup includes PlayStation 5, Xbox Series X|S and Nintendo Switch 2; PC distribution includes Steam, Battle.net and Xbox on PC.
This release guide concentrates on practical preparation rather than a review score. Check your purchase platform, the mode you want to play, and the entitlement attached to your edition before downloading. Preloading places files on a device; it does not itself unlock a mode. Likewise, the full-game calendar date is not enough to convert every platform into a single worldwide launch instant. The official PC article gives additional timing and storage guidance, while the editions page explains which rewards and early-access benefits belong to each purchase.
When can you play Call of Duty: Modern Warfare 4?
The source-backed release date in this record is October 23, 2026. This is a calendar date. It does not establish the time the game unlocks in a particular region.
October 23 is the full-game calendar date. Campaign and DMZ preorder access have separate dates. The official PC article describes PC full release as midnight local time; we do not extrapolate that wording into a universal UTC instant or console unlock hour.

Compare 2026 release dates ↗MW4 launch and early-access dates
Full game: October 23, 2026, on the announced PC and console platforms. The main release-date table refers to this full launch, including Multiplayer.
Campaign early access: October 16 (PT), for an eligible digital preorder. This does not also open DMZ or every Multiplayer mode.
DMZ early access: October 20 (PT), for an eligible digital preorder. It is a separate entitlement window from the Campaign start.
The PC article describes full launch as midnight local time on October 23. We have not established a single UTC launch time for every PC storefront, console and account region. Use the time shown for your own purchase; the early-access announcements also warn that actual availability and dates can change.
PC preload time and storage preparation
Digital PC preloading is scheduled to start October 15 at 9 AM Pacific Time. For that date, the same instant is October 15 at 16:00 UTC. This PC-specific schedule is not a console preload announcement.
Before the window opens, sign in to the storefront used for the purchase and confirm that the correct edition is in your library. When its official preload control becomes available, follow that launcher’s instructions. A missing control is a reason to recheck the storefront, not to download an unofficial installer.
The official minimum and recommended PC specifications list 115 GB of SSD storage. This is not a verified download-file size. Installed components, updates and launcher packaging can alter the space or transfer shown on your device; read the launcher’s current requirement before starting.
PC requirements also include TPM 2.0 and Secure Boot. Use Activision’s own support guidance for eligibility and setup rather than treating a storage check as proof that the PC meets every requirement.
Standard Digital or Vault Edition?
For the stated Campaign and DMZ early-access benefits, an eligible Standard Digital preorder already qualifies. Vault is a decision about the additional bundle content, not a requirement to enter those early-access periods.
Activision lists Vault additions including operator packs, weapon blueprints, a one-season BlackCell entitlement and DMZ bonuses. Season-related content has its own availability conditions. Compare the extras you actually want with your regional store price and terms.
The support page permits a separate upgrade for eligible Digital Standard owners and excludes physical editions from that upgrade route. Confirm the edition and platform account before purchase; we do not assume every disc, subscription or regional offer has the same entitlements.
Which platforms are listed?
The linked sources list PC, PlayStation 5, Xbox Series X|S, Nintendo Switch 2. We retain the official hardware names rather than treating a console family as a guarantee of support on every model.
Platform support does not establish cross-play, cross-save, subscription access, regional store availability or an upgrade entitlement. Follow the relevant official listing for those details.
Release date tracking
No independently verified previous release date is stored in this record. We do not label a game as delayed without source evidence for both the earlier schedule and the change.

When do Campaign and DMZ early access begin?
Activision lists October 16 (PT) for Campaign and October 20 (PT) for DMZ, for eligible digital preorders. Those dates do not establish an exact hour for every platform; availability can change.
When can PC players preload MW4?
The official PC article schedules digital PC preloading for October 15 at 9 AM Pacific Time, equivalent to 16:00 UTC on that date. This is a download start, not an unlock time.
Is the MW4 preload download 115 GB?

Do I need Vault Edition for early access?
No: eligible Standard Digital preorders and Vault Edition preorders both receive the stated Campaign and DMZ early access. Vault adds separate bonus content; compare the regional checkout terms before paying for those extras.
