Call of Duty MK32 – The Six-Shot Grenade Launcher

Jun 5, 2025 | 0 comments

The MK32 is a powerful six-shot grenade launcher in Call of Duty: Ghosts. It uses Semtex rounds to deal heavy damage and serves different roles in Campaign, Multiplayer, and Extinction.

This guide explains how the MK32 works, how it changes across game modes, and how to use it effectively.


What Is the MK32 in Call of Duty?

The MK32 is a revolving cylinder grenade launcher. It fires two Semtex grenades in quick succession and holds six grenades per magazine. It appears in Campaign, Multiplayer, and Extinction modes. In Campaign and Extinction, the MK32 functions as a semi-automatic launcher. In Multiplayer, it fires two-round bursts. The MK32 is classified as a launcher-type weapon and is only available in Call of Duty: Ghosts.


MK32 in Campaign Mode

Availability

You can use the MK32 during the mission “Struck Down.” It’s equipped with a Holographic Sight and functions as a semi-automatic launcher.

Behavior

At the start of the mission, grenades require remote detonation to explode. After that section, they explode instantly upon impact, acting more like standard impact grenades. The campaign version also has a “safe distance” mechanic that prevents self-damage in close proximity.

Key Points

The MK32 is accurate enough to deal with enemy vehicles. Its grenades transition to instant detonation mid-mission, changing its utility. This launcher is not found outside of this specific mission.


MK32 in Multiplayer

How It Works

In Multiplayer, the MK32 is a secondary weapon. It does not use sights but slightly zooms the screen when aimed. It fires two Semtex grenades at once and has a six-round cylinder.

Limitations

The MK32 cannot be reloaded mid-magazine, and only one magazine is available by default. Ammunition cannot be recovered using Scavenger or Fully Loaded. Each shot causes significant recoil, making it hard to land both grenades on the same target. Aiming slightly downward during firing helps with control.

Best Use Cases

The MK32 is ideal for clearing objectives or removing enemies hiding behind cover. It’s especially effective in close- to mid-range skirmishes where splash damage can dislodge enemies from safe positions.

Tips

  • Avoid using the MK32 in close quarters unless you have cover.
  • Fire quickly and retreat before attempting a reload.
  • Its lack of precision and ammo limits make it unsuitable for extended fights.

MK32 in Extinction Mode

How to Access

In Extinction, the MK32 is found under the Equalizer category and costs $2000 to deploy. It functions as a semi-auto weapon and fires grenades that explode on impact, rather than Semtex.

Restrictions

While the MK32 is active, players cannot use other weapons or abilities, except for Melee. The launcher cannot be discarded until all ammo is used. Reloading is only possible once the magazine is empty, which slows down response time in combat.

Upgrade Path

The initial MK32 is a basic six-round explosive launcher. The first upgrade adds a blast shield to protect the user from self-damage. The second upgrade improves movement speed and increases the explosion radius. The third upgrade changes the grenades to incendiary types, allowing them to kill Hunters and Scorpions with one shot. The final upgrade increases grenade capacity from 6 to 12 by adding 6 extra rounds in reserve, though players must reload to access them.

Performance Notes

The MK32 is highly effective against large groups but underperforms against Rhinos. Early in the game, it does not generate enough returns from weak enemies like Scouts. Its full potential becomes apparent in later stages when stronger Cryptids appear. Once upgraded, it can eliminate multiple enemies with a single grenade.

Reloading Problems

Reloading is slow and cannot be easily canceled due to the default On the Go perk. Players should only reload in safe areas or during low-intensity moments.


Best Class Pairings for Extinction

Engineer is a strong pairing with the MK32. It increases the wallet size and provides more income, making the launcher less financially risky. Weapon Specialist is also recommended, as it significantly reduces reload time and improves damage. Players with the Double Class Upgrade can combine both Engineer and Weapon Specialist for greater damage output, faster reloads, and higher earning capacity.

Alternate Strategy

Coordinate with teammates to provide support, such as laying down Team Boosters to counteract the slow reload. Only invest in the MK32 if you plan to upgrade it fully, as the weapon is far less effective when left in its base form.


Important Details and Trivia

In the Campaign, the MK32’s rounds glow red during reloading, a detail missing in Multiplayer and Extinction. The grenade casings are visibly smaller than the chamber and roll around during reload animations. The cylinder slightly clips into attached optics, such as the Holographic Sight. In Extinction, the player character may refer to the MK32 as a “War Machine” or “Grenade Launcher.”


When to Use the MK32

Use the MK32 if you need to eliminate groups quickly or disrupt enemy positions in objective-based modes. It’s also a good option for area denial. In Extinction, it excels when fully upgraded and used against tougher enemies like Hunters and Scorpions.

Avoid using the MK32 against Rhinos or during early-game waves in Extinction, where its high damage does not translate into efficient use of resources. Also, skip it if you prefer flexibility in switching weapons or need fast reloads.


Final Thoughts on Call of Duty MK32

The MK32 can be a powerful weapon when used the right way in Call of Duty. In Multiplayer, it helps clear stubborn defenders. In Extinction, it becomes a high-damage tool for crowd control, but only after full upgrades. If you’re not prepared to commit to its upgrade path and class support, you’re better off with other options. Use it with care, and always stay aware of its reload limitations and ammo restrictions.
