Call of Duty: Mobile Season 11 is here and it’s brought a map from Black Ops 4, some fan-favorite weapons, and a Holiday-themed event. Here’s everything we know about CoD Mobile Season 11 – Final Snow – including its full patch notes.

2021 has been a huge year for Call of Duty: Mobile, bringing in season after season of huge content updates. Now, with Season 10 coming to an end, Season 11 has marked CoD Mobile’s final major update of 2021.

Season 11, set to be titled ‘Final Snow,’ will bring weapons and maps from the Black Ops series, as well as updates to the fan-favorite Undead Siege mode, and a leaked Holiday event.

Here’s everything we know about CoD Mobile Season 11.

CoD Mobile Season 11 release date & time

Call of Duty: Mobile Season 11 went live on December 16 at 4 PM PT / 7 PM ET / 12 AM GMT (December 17) after the ‘One Last Farewell Event’ concluded.

As usual, there was no downtime between seasons so players could get stuck right in to the new content.

CoD Mobile Season 11 D13 Sector and PKM

Call of Duty: Mobile devs teased even more weapons from CoD’s history, with Modern Warfare’s PKM and Black Ops 3’s D13 Sector arriving in Season 11.

These weapons were leaked ahead of Season 10, but now we know that they were intended to release with Final Snow.

The D13 Sector is a “Single shot blade launcher” that “shoots deadly, ricocheting discs, each capable of slaying multiple foes,” and the PKM is a low-recoil LMG.

The PKM can be unlocked as part of the Battle Pass, and the D13 Sector will be made available through a challenge later in Season 11.

CoD Mobile Season 11 patch notes

Balance Adjustments


Compared to the popular weapons, the CBR4 is more difficult to control in the current meta. The weapon has a large Get-Hit flinch that negatively impacts the gaming experience. Therefore, we improved the weapon handling for the CBR4.

  • Base Get-Hit flinch reduced
  • Recoil adjustment, optimize the abrupt trajectory to the upper right, so that the recoil is more steady when firing continuously.

Kilo Bolt-Action

The Kilo Bolt-Action’s base ADS time gives no advantage amongst other shooter rifles, and the disadvantage the ADS time given by the barrel attachments is vigorous. While the gun’s range is not dominant and the overall ADS speed is slow, we have slightly improved the overall ADS speed of the gun.

  • Base ADS Time: 0.4 -> 0.38
  • MIP Extended Light Barrel: ADS Time: +10% -> +7%
  • OWC Ranger Barrel: ADS Time: +15% -> +12%
  • OWC Marksman Barrel: ADS Time: +15% -> +12%


The slow fire rate of HS0405 did not meet anticipated results. Though the single shrapnel has a higher damage benefit, the excessive emission puts the actual combat intensity at a disadvantage. Therefore, the weapon emission is now reduced.

  • Hipfire Bullet Spread reduced
  • ADS Bullet Spread reduced

500gr Slug

  • New effect: Reduce ADS spread
  • Enhance effect: Damage Range

Scorestreaks – Stealth Chopper

Stealth Chopper’s defense is slightly improved.

Bug Fixes

Battle Royale


  • Fixed an issue where the BR general accuracy bonus did not take effect on R9-0
  • Hipfire and ADS bullet spread: Compared to MP, reduced by 30%


  • Updated the models of boulders on Hovec Sawmill
