MW4 5 November update: Hardcore health cut to 22, DMZ duplication fixes and FOB changes

Infinity Ward added a second set of fixes to the 5 November notes, rolling out later that day with the start of Season 1. There are no weapon balance changes, but Hardcore health drops, a Proximity Mine exploit is gone and DMZ gets a long list of fixes, including duplication exploits and FOB vendor changes.

Multiplayer

• Hardcore health is lowered from 30 to 22, so Hardcore modes get a little more fragile.
• Exploits closed: Proximity Mines can no longer be attached to Seeker Drones, and an out-of-bounds spot at Wolves Stadium in Combat Outpost is fixed.
• The Cronen Osprey with the Helix MK. II Apex Attachment no longer clips through the player during Finishing Moves.
• Progression: Boksu Prime now unlocks after finishing the Classic Prestige 10 Track, and the Mercurial Drift Weapon Mastery Camo unlocks once its requirements are met.
• Quickplay: the Edit Quickplay Modes menu gets a Select/Deselect All option.
• Inflation: the “Cash Dropped” notification now appears on eliminations, and the personal Cash counter no longer doubles.
• Kill Block 24/7’s loadout menu no longer overlaps the map preview, and several Private Match and splitscreen issues are fixed, including a crash when the second splitscreen player generated a weapon with Gunny.

DMZ

• Duplication exploits have been fixed, and FOB vendors, recipes and assembly requirements are updated.
• Battery spawn rates at Banks are reduced.
• Sedative Inhaler now works while you hold a Knife, and the Free Prep Trait gives a random Consumable instead of only Radiation Blockers.
• Possum now fully restores health after a revive.
• The Apex .50 GS Magna Pistol no longer vanishes from the Backpack when deploying into Hajin, and Hydrochloric Acid (an unused crafting material) no longer appears as loot.
• AI and vehicles: enemy AI melee damage no longer depends on their weapon, Colossus no longer spawns at the Military Base before the Armory opens, RHIBs stop stacking on the Hajin Shoreline, and Tanks no longer bounce over Razor Wire.
• Fixes to the Exfil countdown when boarding a helicopter another player called in, the Door Breacher prompt in the Supreme Leader’s Bunker, and UAV pings showing while enemy UAVs are active.
• Progression and UI: High-Value Escort Calling Card progress and Lieutenant Dog Tag Camo credit now track properly, the Bounty Leaderboard Friends tab shows your own rank, the Dog Tag Case lists the newest tags first, and the Military Base mission UI now recommends the 3-Plate Armor Vest.

Global

• The Gunsmith now warns you when changing Receivers that it may affect appearance or function.
• Gunsmith fixes: the Horizontal Compensator is back in Cronen Osprey Muzzle options with an Apex Attachment and Barrel equipped, the Bruen Field-OP Optic reticle matches its preview on Pistols, and navigation after selecting a locked Attachment works properly.
• Smaller UI fixes cover the XP Token prompt, the Audio Settings reset text, Calling Card Showcase “Default Fill” and QuickNav tooltips.
