MW4 October 30 Patch Notes: DMZ Side Ops Now Pay 4x, Dynamic Ops Double and Infected Is Live
Infinity Ward slipped one more Modern Warfare 4 update in before Halloween weekend, and this time it came with real numbers. The official October 30 patch notes put hard figures on DMZ cash rewards: Side Ops now pay four times as much and Dynamic Ops pay double. The same update adds Infected to the playlist and fixes crashes, exploits and a handful of DMZ mission bugs.
Our October 29 patch breakdown covered a "slight" DMZ cash bump that came without any numbers. The October 30 notes go much further, and this time they list exact payouts.
DMZ cash: the new numbers
Infinity Ward says the change is meant to improve the in-game economy. Here are the new payouts:
- Dynamic Ops: 5,000–10,000 Cash → 10,000–20,000 Cash
- Side Ops: 500 Cash → 2,000 Cash
- Mission Steps: 300 → 500 Cash per completed step
What it means for your DMZ runs
Side Ops get the biggest jump. They used to pay almost nothing, and now each one is worth 2,000 Cash, so detouring for them on the way to exfil finally makes sense. Dynamic Ops are still the big earners, and at up to 20,000 Cash apiece they're now worth planning a whole run around. The smaller bump for Mission Steps also adds up over a long mission chain. Cash ends up in your pocket faster across the board, which matters for loadouts and FOB spending ahead of Season 1.
DMZ bug fixes
The patch notes also fix several DMZ mission blockers:
- Broken Resupply: the required mission item could be missing from the marked vehicle's trunk.
- Information Power Order: Intel sometimes couldn't be bought from the Boss Board, which stalled progress.
- Hunt Operator: the mission timer was missing, and objective text showed up on the in-world marker.
- Helmet hits: the icon for damaging but not breaking a helmet was white instead of blue.
- FOB: shadows that could suddenly shift, plus a crash caused by spamming knife attacks.
Infected joins the playlist
Infected is now live as a Halloween Party Mode, a day after Possession, which arrived with the October 29 update. We covered both modes in our MW4 Halloween week preview.
Multiplayer and global fixes
According to the official notes, the update also:
- Fixes several issues that could crash servers mid-match.
- Fixes Platinum camo progress for Marksman Rifles not displaying correctly on PC.
- Makes Calling Card Challenges in the Multiplayer lobby show the challenge name instead of the reward name.
- Fixes a black screen after auto-assign team switching while waiting for a Private Match.
- Stops players from getting kicked for inactivity too early in Search and Destroy.
- Closes exploits on Coal.
