This close-range weapon is available to unlock at Tier 21 of the Season 4 Battle Pass, so don’t forget to level up quickly when the update arrives.

Season 4 of CoD Mobile will also bring the Sidearm Scuffle Seasonal Challenge on May 2 which allows players to unlock the Makarov pistol.

New Arsenal map in CoD Mobile Season 4

Arsenal has all of the qualities of a competitive Call of Duty map.

CoD Mobile Season 4 introduces players to a brand-new map in Arsenal. The map originally debuted in Call of Duty: Black Ops 4, and it’s now made its way to CoD Mobile with the Veiled Uprising season.

Arsenal takes players to a “weapons and robotics manufacturing facility where some of the series’ most devastating Scorestreaks have been developed.”

The new map features both outer areas on the perimeter, as well as an indoor component at the center.

The Ground War Skirmish mode will debut in CoD Mobile Season 4.

Ground War: Skirmish is a new mode in CoD Mobile in Season 4. The devs are delivering a new concept with Ground War: Skirmish by fusing components of multiplayer and battle royale.

In this hybrid mode, players get the chance to choose their loadouts and engage in a 12v12 battle.

Two teams “fight for control over five objectives scattered throughout the map.” The mode is expected to be a chaotic new addition to CoD Mobile, but with a little teamwork dominating the objectives will prove rewarding.

Balance Adjustment

HG 40

Even though mobility gives HG 40 an edge, the weakness on damage limits its overall performance.

Chest damage multiplier: Increased

Upper arm damage multiplier: Increase

DR-H

Some attachments were equipped on DR-H to improve range and accuracy. However, most of these attachments cost too much on mobility. Basic ADS enhancement can make a good balance between these options.

ADS speed: Increased

ADS bullet spread: Reduced

AS VAL

AS VAL has a decent ADS speed, but the lack of attachments for specializing ADS speed limits its performance in close-range combat. Therefore, ADS time was reduced appropriately for ensuring its position.

Meanwhile, ADS bullet spread was reduced for improvement on its performance in mid-range combat.

ADS speed: Increased

ADS bullet spread: Reduced

M13

The buff on M13 attachments has constraints which limits the variety of optional attachment sets. Some of them should be adjusted for the situation.

RTC Heavy Long Barrel

Bullet speed buff: Added

RTC Silencer Barrel

ADS speed debuff: Removed

ADS bullet spread debuff: Removed

Range buff: Added

Bullet speed buff: Added

Recoil debuff: Increased

RTC Combat Stock

Players who use Type 25 must choose between stability and burst of mobility. Thus, we have adjusted the attachments to emphasize these two different aspects more prominently.

RTC Steady Stock

Get-hit flinch resist buff: Increased

Get-hit flinch buff: Increased

YKM Combat Stock

ADS speed buff: Increased

Get-hit flinch resist debuff: Increased

Get-hit flinch debuff: Increased

Krig 6

Firm Grip Tape

Cordite

Cordite shows the lack of steady damage and burst compared to the majority of SMGs, which makes it mediocre in the current combat environment.

Damage: Increased (MP Only)

Head damage multiplier: Increased

Lower arm damage multiplier: Increased (MP Only)

Range: Increased

Razorback

Razorback performs slightly inferior to the majority of SMGs in terms of lethality even with the buff from Rapid Fire. We increased its damage for medium and long ranges and made it perform more effectively with close-range headshots.

Damage: Increased

Head damage multiplier: Increased

PDW-57

Both range and TTK of PDW-57 should be strengthened to SMG’s average as it remains a low usage rate.

Lower arm damage multiplier: Increased

Range: Increased

PPSh-41

PPSh-41, which is known for its hip firing, hardly shows an edge as the low damage stability and long sprint-to-fire delay set a limit to its advantages.

Damage: Increased

Sprint-to-fire delay: Reduced

HDR

HDR takes a relatively long time for aiming down the sight in combat for the shortage of attachments that buffs ADS speed. The 1st DMG range also seems inadequate in some MP maps.

Article continues after ad

ADS speed: Increased

Range: Increased

Outlaw

Although Outlaw is ahead of other Sniper Rifles in terms of mobility, it lags them in overall performance. It should be strengthened to guarantee its position.

Range: Increased

Get-hit flinch: Reduced

Basic steady aiming count-down: Increased

MK2

High damage of MK2 is not enough to make up for its deficiencies in mobility, which make it underutilized in a variety of Marksmans.
