Preload Dates and Eligible Editions
We separate the download date from campaign access because installing the files does not grant an early start.
Neowin's September 29 report gives the PC preload date. Game Rant's campaign report identifies eligible digital preorders.
Here is the schedule supported by those sources.
| Event or requirement | Date or eligibility | Evidence |
|---|---|---|
| PC preload | October 15, 2026 | Neowin reporting |
| Campaign early access | October 16, 2026 | Neowin and Game Rant reporting |
| Full release | October 23, 2026 | Official Call of Duty PC announcement |
| Campaign early-access purchase | Standard Digital or Vault Edition preorder | Game Rant reporting |
| Precise start times and console preloads | Not established by the reviewed source text | Check your platform listing |
Do not pay for Vault solely for campaign access if your Standard Digital preorder already includes it.
Check the Purchase Before the Download
Read the campaign-access benefit on your platform's product page. Beta access, campaign access, physical purchases, and subscription access are not interchangeable entitlements.
If you purchased through a retailer, check whether the order supplies a redemption code. Confirm that any required code is redeemed on the account you will use to play.
PC Storage: 115 GB Is Only One Check
The PC requirements reproduced by Neowin specify 115 GB and an SSD across all three hardware tiers. A hard drive with sufficient free space does not meet the stated storage requirement.
The official PC announcement confirms PC availability through Xbox on PC, Battle.net, and Steam.
Prepare the Correct Drive
We recommend checking both the destination drive and the selected content:
1. Choose an SSD as the installation destination.
2. Check its available space against the installer's current requirement.
3. Review which campaign packs and dependencies are selected.
4. Remove optional content only where installation management identifies it.
5. Follow any additional temporary-space requirement displayed by the installer.
Do not interpret 115 GB as a verified campaign-only download size. The reviewed reporting does not specify a separate campaign package, nor does it substantiate the earlier draft's fixed 10 GB allowance.
Campaign Installed but Access Blocked?
Check the start time and account before reinstalling. Repeating a large download does not resolve an ineligible purchase.
Use the symptom to choose the next check.
| What you see | Check first | Avoid |
|---|---|---|
| Campaign unavailable before its start | Current platform access schedule | Reinstalling to gain earlier access |
| Purchase or entitlement message | Purchasing account and redemption status | Buying another edition immediately |
| Missing-content message | Campaign packs and required dependencies | Deleting the whole shared application |
| Error after those checks | Exact error text and official service notices | Repeated downloads without identifying the cause |
Reinstall only when the error or platform support instructions point to an installation problem.
FAQ (Frequently Asked Questions)
When can you preload Modern Warfare 4 on PC?
PC preloading is reported to start October 15, 2026. The reviewed Neowin article does not provide a precise starting hour.
When does campaign early access begin?
Campaign early access is reported for October 16, 2026. Check your platform's current listing for the exact start time and applicable time zone.
Do you need Vault Edition for campaign early access?
No—Game Rant reports that Standard Digital preorders also qualify. Confirm the benefit on your platform before purchasing an upgrade.
How much PC storage does Modern Warfare 4 require?
The published PC requirements specify 115 GB on an SSD. Use the installer's current requirement for your selected content and any additional working space it requests.
Can you play DMZ during campaign early access?
Game Rant places DMZ with the October 23 full release, not the October 16 campaign window. The official release hub is the reference for subsequent mode announcements.
