Infinity Ward today released a new update for Call of Duty Modern Warfare. We have the full patch notes for this update on February 4.

The Modern Warfare Update 1.31 is now available for download, for all platforms. On the PS4, the file size is around 11.4 GB.


Modern Warfare Patch Notes 1.31


  • New fix to remove infinite stim glitch
    • Issue stemmed from player getting stuck in throwback state after throwing back a live grenade
  • Adjusted match bonus and kill XP reward of Kingslayer mode to be more in line with Verdansk BR
    • This is part of our continued effort to normalize XP rewards across our various game modes


  • Adjusted the timing of ammo replenishment during empty reloads for BOCW weapons


  • Certain operator missions for Stitch should now track as intended


  • Fixed visual for the “Heavy Handed” Sledgehammer in the Player Armory


  • Fixed issue where at high prestige levels, progress towards next level shown in Barracks Seasonal Progression did not match what was shown on the top banner of the main menu


  • Removed Tier Skips from Modern Warfare Bundles
  • Previewing Bruiser Cord watch in the Hot Shot Bundle will now display correct watch
  • Fixed various minor issues including images, icons, and names


  • Fixed a crash that occurs when launching the game due to changes being made to Windows GDI32

Hopefully, this is the last we see of the Stim glitch make an appearance in the game.

    I gain XP for battle pass and rank but my guns do not level up. I usually get pretty high in the leaderboards but decided to get last and then gain XP. Is this some kind of new thing for bad players to level up or what. Kind of frustrating. Xbox.

    The file size is inaccurate … I had over 90GBs of space available and it still made me delete a different game to download the 1.31 version …. and then used up 70GBs, placing it all inside the Other file under Storage. Someone is lying about the update.

      Same here. I had to delete over 70GBs to make room as well.
