For submachine gun referred to as "MX9" in Call of Duty: Modern Warfare II, see AUG (submachine gun).

The MX9 (stylized MX-9) is a submachine gun featured in Call of Duty: Black Ops 4 and Call of Duty: Mobile.

Call of Duty: Black Ops 4[]

"Full-auto submachine gun. Balanced fire rate with moderate recoil."
— In-game description

The MX9 is a submachine gun developed in Germany by the fictional manufacturer Kühn & Schmidt. It also has an MKII variant and a Mastercraft variant called the Soldier of Fortune.

Multiplayer[]

The MX9 is a middling SMG that boasts mostly average characteristics. Its time-to-kill is about average for the submachine gun category, enabling it to edge out most assault rifles in close quarters with sufficient accuracy. Moderate damage coupled with a high rate of fire enable this weapon to win most engagements in close quarters.

However, beyond close range, the MX9's recoil has a tendency to pull the sights off target, and can be difficult to control. Combined with the MX9's large iron sights, equipping an optical sight such as the Reflex and ELO may assist in close-quarters battles.

Handling is about average for the SMG category. The MX9 has no particular strengths or weaknesses in regard to reload time, raise time, or ADS time. The 35 rounds in the magazine can be expended rather quickly due to the high RPM, so spraying is not recommended unless as a last resort option.

As such, the MX9 can struggle in prolonged gunfights, especially when taking on two or more enemies at a time.

Zombies[]

The MX9 appears in the Zombies maps Voyage of Despair, IX, Blood of the Dead, Classified, Dead of the Night, Ancient Evil, Alpha Omega and Tag der Toten where it's available as a weapon to purchase from the wall or the Mystery Box.

When upgraded via Pack-a-Punch Machine, it becomes the Nueve Muertes XX with the magazine size increased to 55 rounds (70 w/ Hybrid Mags) and its ammo reserve increased to 330. It is unlocked for customization in the armory al level 25.

Attachments[]

The MX9 has a diverse set of attachments, focused on improving all aspects of its performance. The MX9 lacks an Operator Mod or any tiered attachments, fitting its "jack of all trades, master of none" weapon profile.

Call of Duty: Mobile[]

"Fully automatic submachine gun with high close-range damage but strong recoil."
— Description

The MX9 returns in Call of Duty: Mobile. It was added in July 2021 as part of the Season 6: The Heat update.

Multiplayer[]

The MX9 sports a higher than average fire-rate for SMGs, but it does not surpass weapons like the Fennec. It can earn a consistent four-shot kill in close range, but the Large Caliber ammo is available, decreasing this to a three-shot kill to the torso. Thanks to its higher-than-average firerate, along with consistent damage, it is quite powerful in close range to mid range, even beating out the Fennec if the user has good enough aim. However, the major weakness of the MX9 is a lack of range. It lacks attachments to increase its range, and the damage drop-off is quite severe past 20 meters.

Compared to other SMGs in class, it is more oriented to close-range, but its damage at longer ranges has something to be desired. As it also has vastly different attachments from the rest of its class, the player will need to be aware of how the gun can be modified.

In general, the MX9 serves as a close to mid-range oriented submachine gun with limited usability at long range, and compared to the rest of its class, is more oriented towards mobility in terms of attachments.
