Call of Duty: Modern Warfare 4 has received a fresh update, with Infinity Ward publishing new patch notes on October 25, 2026 that outline a round of fixes and adjustments rolled out to players. According to the studio, the update addresses issues reported by the community and includes additional gameplay adjustments and improvements across the experience.
The headline fix targets a launch problem on two platforms. Infinity Ward says the update resolves an issue on Xbox and PC where players using the full Korean language setting could not launch Black Ops 7 from Modern Warfare 4. With that blocker cleared, affected players should now be able to move between the two titles without hitting the startup failure.
Beyond that specific fix, the October 25 patch notes describe broader work on gameplay feel, with the studio noting additional adjustments and improvements bundled into the release. As is typical for Call of Duty updates, the changes are intended to smooth out problems players have surfaced since launch and keep the experience running steadily across platforms.
Infinity Ward also pointed to what is coming next. The studio says it is looking at potential weapon tuning changes for a future update, so balance work may still be on the table as the team continues to monitor player feedback after this patch. No date for that follow-up has been announced.
Modern Warfare 4 is available on PC via Steam, where it is listed under App ID 4435490, alongside its console releases. Players who want the complete breakdown of what changed can read the full official Call of Duty: Modern Warfare 4 launch patch notes directly from the source.
If you ran into the Korean language launch problem on Xbox or PC, this update should sort it out — jump back in and the Black Ops 7 link should work as intended. And keep an eye on the official patch notes page for the weapon tuning news Infinity Ward has hinted is coming down the road.
