Modern Warfare 4 does not launch on October 23 for everyone. If you pre-ordered digitally, your campaign unlocks a week earlier, and a second early-access window opens for DMZ three days before the full release.
This guide lays out every date Activision has confirmed, who qualifies for Modern Warfare 4 early access, what you can actually play, and the details that are still unclear, so you know what to expect before you hit install.
Checked on October 13, 2026 against Activision’s official Call of Duty pages and Steam. We have not played the game, so nothing here is hands-on.
The Modern Warfare 4 Early Access Timeline
| Date | What happens | Who |
|---|---|---|
| Thu, Oct 15, 9 a.m. PT | PC preload opens | Digital pre-purchasers on PC |
| Fri, Oct 16 | Campaign early access | Digital pre-orders |
| Tue, Oct 20 | DMZ early access | Pre-orders (see the eligibility note below) |
| Fri, Oct 23 | Full release, multiplayer included | Everyone, at midnight local time |
The campaign and launch dates come from Activision’s campaign early access post, and the DMZ date is listed on the official Modern Warfare 4 page. The company adds that start dates are subject to change.
The takeaway: three dates matter, and only the last one is for everybody.
Who Gets Campaign Early Access
Activision says players who digitally pre-ordered or pre-purchased the game qualify. That covers the Standard Digital Edition and the Vault Edition. The official post lists Xbox Series X|S, Xbox on PC, PlayStation 5, Battle.net and Steam.
Physical copies are the catch. Windows Central reports that disc pre-orders from retailers do not qualify, because discs ship at general release. If you want to play on October 16, buy digital.
Nintendo Switch 2 is less clear. Activision’s early access post said Switch 2 pre-orders were coming later in the year, and outlets disagree on whether Switch 2 buyers get the same schedule. Check your store page before you rely on it.
What Time Does Early Access Start?
Activision has not published an unlock hour for the campaign. Its pages say only that actual play time is subject to outages and time zone differences.
Some sites show countdowns anyway. Dot Esports, for example, sets its DMZ countdown to the usual Call of Duty update time of 9 a.m. PT (12 p.m. ET). That is a reasonable guess, but it is an assumption, not an announcement. Plan to be ready around that time, and trust Call of Duty HQ, Battle.net or Steam over any countdown when the day arrives.
DMZ Early Access on October 20
Activision’s Modern Warfare 4 page lists DMZ early access starting Tuesday, October 20. Forbes and Dot Esports both describe it as a perk for digital pre-orders.
The wording is not identical everywhere. GameSpot says you need to pre-order any edition, including Standard or Vault, and lists every platform. The safest reading is the digital one: if you pre-ordered a disc, do not count on October 20.
The takeaway: if DMZ is the mode you care about, you want a digital pre-order, not a disc.
What You Can and Cannot Play Before October 23
- October 16: the campaign. Steam describes the story as a North Korean invasion of the Korean Peninsula.
- October 20: DMZ, for eligible pre-orders.
- October 23: everything else, including multiplayer.
Windows Central reports that multiplayer arrives at the full launch, not before. Treat the early windows as a head start on two modes, not the whole game.
Editions, Prices and the Returning-Player Discount
| Edition | Price (US) | Early access |
|---|---|---|
| Digital Standard | $69.99 | Yes, if pre-ordered |
| Physical Standard | $69.99 | No, per Windows Central |
| Vault Edition (digital only) | $99.99 | Yes, if pre-ordered |
| Vault upgrade from Digital Standard | $30 | Applies to the upgrade path |
Steam lists the Standard Edition at $69.99 and the Vault Edition at $99.99, which matches the prices above.
Activision also offers a 10% discount on the Vault Edition. You qualify if you own and have played a Call of Duty game released in 2019 or later on the same account you use to pre-order. Free-to-play and mobile titles do not count, and the offer runs until October 23.
The official page lists pre-order extras such as the Hunter Killer Operator Skin, the Gilded Pearl Camo Pack, the Inner Circuit Weapon Blueprint, one season of BlackCell and a DMZ Deployment Bonus. The listing does not clearly separate what each edition includes, so read the store page for your edition before you buy.
Is Modern Warfare 4 on Game Pass?
Not at launch. Windows Central notes that, unlike the last two Call of Duty releases, Modern Warfare 4 is not coming to Xbox Game Pass on day one, and it expects the game there no earlier than October 2027. That second part is the outlet’s expectation, not something Activision has said.
PC Players: Fix This Before October 16
Activision says TPM 2.0 and Secure Boot are required to play on PC, and the game needs 115 GB of SSD space. PC preload opens October 15 at 9 a.m. PT for digital pre-purchasers. Because early access is a week ahead of launch, any BIOS changes should be done now. Our Modern Warfare 4 TPM 2.0 and Secure Boot guide walks through the checks and fixes in a few minutes.
Common Mistakes to Avoid
- Buying a disc and expecting October 16. Digital pre-orders are the safe route to early access.
- Trusting a countdown timer. The unlock hour is unannounced, so a countdown is an educated guess.
- Leaving the PC checks until launch week. A missing TPM or Secure Boot setting can cost you an evening.
- Missing the discount window. The 10% Vault discount ends October 23.
- Reading Steam’s date as the launch date. Steam lists October 22 while Activision says October 23 at midnight local time. The gap is likely a time zone effect, so rely on the publisher.

Final Thoughts
Early access turns one launch date into three, and the only thing standing between you and the first one is a digital pre-order and, on PC, a couple of BIOS settings. Check which edition you own today, then recheck the official Call of Duty pages on October 15 in case anything shifts.
