## Other changes in the notes

Short summaries of the rest of the notes, by area. Bug fixes are grouped and not every one is listed. The official notes have the complete text.

### Playlist

- Updated October 27: Shipment 24/7 (new), Frontline, Inflation, Collateral, Kill Block 6v6 Gunfight (new) and Gun Game (new). Free For All keeps its score limit of 30 with a party limit of 2 players. Infinity Ward says Final Killcam will be restored in a later backend update.

### Global

- Movement: to mitigate an exploit that lets a player dive right after a sprint jump to gain a speed boost, dive velocity is reduced by 23% as a short-term measure. Infinity Ward says a long-term fix will not reduce dive velocity.
- Fixed missing progress counters in Camo and Special Camo unlock requirements, the invisible Fungal Grid Camo in the Camo menu, and military Camos showing as locked after a weapon was prestiged. Prestiging from the DMZ FOB now resets Multiplayer Loadouts.

### Multiplayer

- Weapon tuning: the notes say the first broad pass focused on normalizing hit location damage for a more consistent TTK and general improvements to SMG performance. An "edited for clarity" line adds that the changes primarily targeted upper limb damage multipliers for Submachine Guns.
- Quick Fix: damage now interrupts health regeneration from the perk. Infinity Ward says it kept regenerating after damage, making players more tanky than intended. The Quick Fix hitmarker icon was also updated.
- Challenges: the maximum range cutoff for Point Blank tracking is increased and the minimum range cutoff for Longshot tracking is decreased. The notes print no distances.
- Fixed players appearing as Reece in Gun Game regardless of their Operator, and a Riot Shield exploit that reached out-of-bounds areas. Improved UAV visibility on Sentry.

### DMZ

- Possum Trait: it can no longer be activated while the team that killed you is nearby, or until 4 minutes have passed. Infinity Ward says the range and duration can be tuned later, and that Possum was being used as a combat mechanic instead of a survival mechanic.
- Fixed Possum reviving players who had abandoned their Operator, a black screen after a squad wipe with a teammate holding the Possum Perk, lost Free Loadout items after 3D Printer use, and the missing 3-Plate Armor Vest reward at DMZ Level 37. Closed several exploits.

### Known issues

- The notes list Calling Card challenges not tracking as intended, the Best Play selection logic in Multiplayer, and players who enter Classic Prestige through DMZ menus being unable to make new Multiplayer classes until relocked classes are deleted.

## What this update does not say

- The notes print no units for damage ranges, damage values and damage multipliers.
- Values the notes do not list are unknown here. A weapon missing from the tables was not listed as changed.
- The percent change is worked out on this site from the two published numbers.
