MW4 October 29 Patch Notes: DMZ Cash Boost, Faster Multiplayer XP and a Big Round of Fixes

Infinity Ward pushed another Modern Warfare 4 update on Thursday, October 29, 2026, and this one is good news for anyone grinding DMZ. According to the official October 29 patch notes, DMZ now pays more cash for three types of activity, Multiplayer XP earn rates are up across several modes, and the Possession Halloween mode has joined the playlist. The patch also carries a long list of DMZ and Multiplayer fixes.

It's a separate update from the launch patch we covered earlier. Infinity Ward is adding each new update to the same official "Launch Updates" page.

DMZ pays more cash

Infinity Ward calls it "a slight economy adjustment". According to the patch notes, cash rewards are now higher for:

• Dynamic Ops
• Side Ops
• Story Mission replays

The notes don't give exact numbers. Still, replaying missions you already know now earns more than it did before.

Multiplayer XP goes up

The studio says it has "increased XP earn rates across several Multiplayer modes to improve consistency in progression." The notes don't name the modes or give percentages. The Click points out that this follows the October 25 update, which already raised kill XP in Search and Destroy and Collateral.

Possession is live, with a twist

Possession, the Halloween party mode we previewed earlier this week, is now in the Multiplayer playlist. When you eliminate an enemy, you take over their position and loadout. TalkEsport reports that the playlist carries a "Warning: Non-MilSim Content" label, which the @MW4Media account first spotted. The label flags that the mode breaks from MW4's grounded style.

The DMZ fixes that matter

The official notes list these DMZ fixes:

• Enemy helicopters no longer crash into the Exfil helicopter and kill players during extraction. Infinity Ward's comment: "Funny, but not if it happens to you."
• The interaction prompt no longer goes missing from Lieutenant Towers during Side Operations.
• Players can pick up hostages again after assimilating.
• The Scavenger can no longer detect players immediately after they deploy.
• You can pick a Free Loadout with a full Stash if your Active Duty Operator has no equipment.
• Squadmate actions now count toward DMZ Mastery Camo challenges, and Encrypted Voice Logs for the Ears Everywhere Order spawn reliably.
• Players can no longer extract with a disconnected teammate's Dog Tag. Players also no longer get stuck on Hajin terrain or find vehicles overlapping near the map edge. Several exploits are closed.

3-Plate Armor Vest: an earlier fix restored the Level 37 reward only for players who hadn't reached that level yet. Infinity Ward says it is "actively working" on getting the vest to players who passed Level 37 before that fix.

Multiplayer fixes

• Distracting overhead effects removed on Lithium.
• Concussion Grenades no longer show a false red damage indicator.
• A non-functional timer is gone from the Domination scoreboard.
• On Silkworm, the Recon Drone can no longer be deployed out of bounds.
• Redundant enemy callouts on Shipment are removed ("Y'all know enemies are at the Containers").
• Several out-of-bounds exploits on Mumbai are closed.

Twisted Voxel also lists the stability, crash and menu fixes in full.

• October 30: Infected arrives as the second Halloween mode, per Infinity Ward's roadmap.
• November 2: Full Warzone Season 1 intel and roadmap on the Call of Duty blog.
• November 6: Season 1 launches with X01 Black Site in DMZ, the CSG-35 and more. Our Season 1 breakdown has the details.
