Patch notes

Ghost no longer hides you when you fire an unsuppressed weapon, DMZ adds a Scavenger Bonus for failed extracts, and UAVs are switched off in X01.

Bug fixes with no balance changes: X01 bounty levels, Last Stand kills by DMZ bosses, Gunship removal, and a known Steam crash with a workaround.

Season 1 day-one fixes: Thermal Padding and the Sedative Inhaler now hide you from UAVs in DMZ, a Shransit playlist arrives and Hardcore joins Quickplay.

Season 1 adds four maps, the Cronen Osprey and CSG-35, Grind and Drop Zone, and DMZ's X01 black site. It also buffs 14 weapons and nerfs the Hyeon Hyperburst, VEL 46 and APOC-338.

Dive speed restored, the JOKR's infrared mode temporarily disabled, fewer DMZ UAV towers, and longer-lasting Sedative Inhalers.

Infected arrives, and DMZ cash rewards double: Dynamic Ops now pay 10,000 to 20,000 and Side Ops 2,000.

Possession and a Halloween party mode join the playlist, XP rates go up in several modes, and DMZ mission cash rewards increase.

The first big MW4 tuning pass: limb damage normalized across SMGs, range buffs for the Kastov 762 and M4, and nerfs to the Han 86, Oden, Hyeon Hyperburst, APOC-338 and FiNN LMG.

Triple XP per kill in Search and Destroy and Collateral, a rolled-back S&D bomb fix, weapon class corrections and a Drill Charge nerf against the DMZ Colossus.

Hijack spawn improvements, a Search and Destroy defuse fix and a long list of DMZ fixes, including a party bug that left Operators MIA.

Day-one fixes for Modern Warfare 4: camo and Apex unlock bugs after Prestige, DMZ stability, and a promise of weapon tuning the following week.
