DMZ free trial on Steam: until November 11, 2026

Steam lists the Modern Warfare 4 DMZ as a separate app with a free trial running until November 11, 2026 at 10AM PT. The store data carries it as a distinct entry rather than a discount on the full game.

What the store data says

The Steam store page for Call of Duty: Modern Warfare 4 carries a free_weekend record with its own app id and its own start and end timestamps:

Field	Value
Trial name	Call of Duty®: Modern Warfare® 4 - DMZ Free Trial
Separate app id	4269880
Starts	1793995200 — November 6, 2026 at 1:00 PM PT
Ends	1794420000 — November 11, 2026 at 10:00 AM PT

Steam’s own event entry for the trial reads “The DMZ Free Trial begins Now! PLAY DMZ FOR FREE UNTIL NOV 11 AT 10AM PT”, and the summary it attaches to the event describes what the trial covers: “Drop into Hajin and X01, take on new Orders, and fight to extract with your loot through November 11.”

That last detail is the substantive one. The trial is not a limited slice of the mode — the store copy names Hajin and X01 specifically, which are the two DMZ maps in play at the Season 1 launch. X01 is the sealed GRANIT Arms black site that opens with Season 1, described on the DMZ guide.

Why a separate app id

The trial is not a promotion on the Modern Warfare 4 package. It carries its own Steam app id, 4269880, distinct from 4435490, which is Modern Warfare 4 itself. The full game’s entry still shows a release date of 22 Oct, 2026 and a paid price, and the trial record sits alongside it rather than replacing it.

That structure is what lets a player install the DMZ alone. The DMZ has been a separate download since its early access period on October 20, 2026, and the trial continues that separation: a separate app, a separate install, and a separate entry in the player’s library.

The store page also carries a banner linking the trial to the Modern Warfare 4 community hub, so a player who arrives through the free trial is pointed at the same community space as one who owns the game.

What the trial gives access to

The promotional copy names what is playable: “Drop into Hajin and X01, take on new Orders, and fight to extract with your loot through November 11.”

Three things follow from that sentence that are worth stating plainly:

• Hajin is the map with the official DMZ tac map and its thirty-five named points of interest, and it is the map a DMZ player will spend most of the trial on. It has its own map guide.
• X01 is the new area that opens with Season 1 — a sealed, multi-floored GRANIT Arms black site on the edge of Hajin. Official material still marks its further details as classified, so what a player finds there during the trial may be more than this wiki records.
• Orders are the in-match contracts that drive the mode’s loop, and extraction is what the mode is about.

The trial therefore covers the mode as it stands at the Season 1 launch, not an older build. That makes it the cheapest way for a new player to see the DMZ in its current state, and it is also why the DMZ guide’s Cash figures apply to a trial session.

What this is not

This is not a free weekend for Modern Warfare 4 itself. The full game’s Steam entry shows a release date of 22 Oct, 2026 and a paid price, and the trial record sits under a separate app id for the DMZ only.

It is also not a general statement that DMZ is free. DMZ was never a paid mode in the first place — it is a free-to-play mode inside a paid game, and the same package buys access to it. What the trial provides is a way to install and play the mode without buying that package, for the length of the window.

The same store page also carries a “-70%” discount and a “Play for free until Nov 9 @ 10:00am” line. Those belong to a different title in the recommendations column, not to Modern Warfare 4, and this wiki does not treat them as MW4 facts.

What is not published

Steam publishes the trial window, the separate app id and the promotional copy. It does not publish what happens to a player’s progression after the trial ends, whether DMZ stash or FOB contents persist across the transition to the paid package, or whether an account that played only the free trial can keep DMZ access afterwards. No publisher statement on this wiki’s sources addresses those questions.

The trial window is a dated, temporary offer. This page records what Steam’s store data carried on November 9, 2026; once the window has closed the record stops applying.
