How to Get the Mammoth LMG Fast in Black Ops 7 & Warzone Season 5 (Machine of War Event)

The Mammoth LMG is unlocked in Black Ops 7 and Warzone Season 5 by participating in the limited-time Machine of War event and collecting Fuel Cans. It is a heavy-hitting LMG with excellent recoil control but slower fire rate, handling, and mobility compared to other LMGs.

How to Unlock the Mammoth LMG in Black Ops 7 & Warzone Fast

The Mammoth LMG is one of the new weapons arriving in Black Ops 7 and Warzone Season 5. Unlike other seasonal guns, it is not available in the Battle Pass. Instead, you can obtain the Mammoth through the limited-time Machine of War event.

Here’s how you can unlock the new LMG fast in BO7 and Warzone, along with how it compares to other weapons in its class.

The Mammoth LMG is earned by participating in the Machine of War event. During this event, you’ll collect Fuel Cans while playing BO7 Multiplayer, Zombies, Endgame, and Warzone, then exchange them for event rewards.

Activision has not yet revealed exactly how Fuel Cans are obtained. Based on previous exchange-style events, they’re likely to drop from eliminations and by opening loot caches. The total number of Fuel Cans needed to unlock the Mammoth also hasn’t been announced. We’ll update this guide once Activision confirms the Fuel Can requirements as well as the fastest farming methods.

There’s also a chance that the Mammoth will receive a weapon blueprint in a Season 5 store bundle. If you don’t unlock the base weapon before the fifth season ends, it should become available through Armory Challenges in the following season.

How Does the Mammoth Compare to Other LMGs in BO7 & Warzone?

The Mammoth is built as a heavy-hitting LMG with excellent recoil control rather than fast handling. Compared to popular options like the Mk.78 and XM325, it has a slower fire rate, handling, and mobility, but offers higher damage output and better accuracy during sustained fire.

Its reciprocating barrel design keeps recoil manageable during extended firefights, making it a solid choice for long-range engagements and providing covering fire for teammates, particularly in battle royale matches over in Warzone. If you prefer a more aggressive playstyle, you should prioritize attachments that improve handling and mobility, such as Quickdraw Grip, Light Stock, and Fast Mag.

Mammoth LMG Details, Prestige Attachment, and Prestige Camos

Base Stats: Levels: 39 | Magazines: 3 | Magazine Size: 50 | Mastery Badges: Yes

Attachments: Optic, Muzzle, Barrel, Underbarrel, Magazine, Rear Grip, Stock, Laser, Fire Mods

Customize Options: Blueprints, Camos, Reticles, Accessories, Decals, Stickers

The Mammoth’s Prestige Attachment is the 14″ MFS Cascade Barrel, a specialized barrel that removes the weapon’s pre-fire delay and movement penalties while firing. It also improves ADS movement speed, recoil control, and bullet spread, making the LMG more effective during sustained firefights. The trade-off is a slower ADS time, so players should weigh the improved accuracy and mobility against the reduced responsiveness when aiming.

Below are the unique Prestige Camos you can earn for the Mammoth LMG:

  • Prestige 1: Sky Rats
  • Prestige 2: Database
  • Prestige Max (Level 250): Spent

Similar to other Prestige Camos, these are universal, which means you can equip them on other weapons once unlocked.

Season 5 also introduces the FG 42 assault rifle and Gremlin SMG as other new weapons to unlock. You can also check out our breakdown of the Black Ops 7 and Warzone Season 5 roadmaps for all upcoming maps, modes, weapons, and gameplay features.

Why This Matters

The Mammoth LMG is a powerful new weapon exclusive to the limited-time Machine of War event, meaning players must act quickly to unlock it before Season 5 ends or wait for a later Armory Challenge. Its unique stats and Prestige Attachment offer a distinct playstyle advantage in both multiplayer and battle royale modes.

Background

Machine of War Event

This is a limited-time event in Black Ops 7 and Warzone Season 5 where players collect Fuel Cans by playing various game modes. Fuel Cans are exchanged for event rewards, including the Mammoth LMG. Similar events have been used in previous seasons to introduce new weapons.

Prestige Attachments and Camos

Prestige Attachments are special weapon mods unlocked at higher levels that significantly alter weapon performance. The Mammoth's Prestige Attachment, the 14" MFS Cascade Barrel, removes pre-fire delay and movement penalties while improving ADS movement speed and recoil control. Prestige Camos are universal cosmetics earned at specific Prestige levels (1, 2, and Max at Level 250).

Armory Challenges

Armory Challenges are a system introduced in previous Call of Duty titles that allow players to unlock weapons they missed during seasonal events. If the Mammoth LMG is not obtained during Season 5, it will likely be added to Armory Challenges in a future season, providing a second chance for acquisition.
