Call of Duty: Modern Warfare 1.04 Update Patch Notes

The Modern Warfare 1.04 update has landed, with the Modern Warfare 1.04 patch notes going live on PS4, Xbox One, and PC. The version 1.04 update has been pushed out by developer Treyarch on its release day as a day one patch.

Modern Warfare 1.04 patch notes

The Modern Warfare 1.04 update measures in at 1.804GB on PS4 and Xbox One, but a sizable 7 GB on PC. It’s not yet known what changes it has introduced across platforms, but it’s clear that the PC version of the game has been impacted the most dramatically.

Publisher Activision has yet to reveal what changes have been made in this brand new update, though it follows closely on the heels of the 1.03 update. It’s clear that some extensive tinkering is going on behind-the-scenes to ensure that Modern Warfare‘s launch runs as smoothly as possible.

We’ll update this post when the 1.04 patch notes go live.
