Season 05 has landed in Black Ops 7 and Warzone, bringing its own dedicated grind. The Machine of War event tasks players with collecting Fuel Cans across every mode and cashing them in for a fresh arsenal of rewards, headlined by the new Mammoth LMG and a pair of standout camos. Here’s everything confirmed so far in this BO7 Machine of War event guide, plus what’s still up in the air.
What Is the BO7 Machine of War Event?
Machine of War is Black Ops 7’s Season 5 collection event, running across Multiplayer, Zombies, Endgame, and Warzone. The idea is simple: play matches, earn Fuel Cans, and cash them in for cosmetic and weapon rewards. The event runs from July 30 to August 13, 2026.
How to Earn Fuel Cans in BO7 and Warzone
Fuel Cans can be earned simply by playing through the Machine of War event window. Activision has confirmed that all supported modes contribute to your Fuel Can total, and outside reporting backs this up: Multiplayer, Zombies, Endgame, and Warzone all count. Activision has not published a daily or account-wide cap for Fuel Can in its public event documentation.
Some players report that Casual Battle Royale and Resurgence are efficient for collecting Fuel Cans, but Activision has not confirmed a fastest mode or playlist.
Machine of War Rewards: Mammoth LMG, Camos and More
Here’s every reward you can get in the Black Ops 7 Machine of War event.
| Reward | Type | What It Is |
| Mammoth LMG | Weapon | A new Light Machine Gun added for Season 5, themed around the event’s killer-robot aesthetic |
| Puffed Up | Weapon Camo | A standard weapon camo tied to the Machine of War track |
| Soul Eater | Universal Weapon Camo | Applies across your weapon arsenal rather than a single gun |
| Piston | Reticle | A cosmetic sight option for weapon optics |
| Mechanic Preparation | Loading Screen | A cosmetic loading screen themed to the event |
The patch notes note there are “more rewards” tied to the killer-robot, heavy-metal theme beyond this named list, without giving an exact total.
The Mammoth LMG also slots into BO7’s broader Season 5 arsenal. See our Black Ops 7 Season 5 Content Drop: New Weapons, Maps & Zombies Finale for the full weapon lineup.
Is the Mammoth LMG Usable in Ranked Play?
The Mammoth LMG is restricted from Ranked Play during its launch window, with the restriction remaining in place for the duration of the EWC tournaments.
Final Thoughts: Should You Rush the Machine of War Grind?
You don’t need a dedicated grind session. Playing your usual BO7 and Warzone rotation steadily through August 13 should give you plenty of opportunities to collect Fuel Cans.
This favors players who already log in daily over anyone trying to cram it in during the final days. If you’d rather skip the wait entirely, you can explore BO7 boosting and camo unlock services to speed things along. For camo hunters chasing more than just Soul Eater, our How To Get End of Days Camo BO7 Fast? guide covers another fast unlock path.
FAQs
1. When does the BO7 Machine of War event end?
The event will end on August 13, 2026.
2. Can I still get the Mammoth LMG after the event ends?
Activision has not confirmed whether the Mammoth will have another unlock method after the Machine of War event ends. For now, the safest option is to unlock it during the event.
3. Which modes earn Fuel Cans fastest?
High-elimination respawn playlists (such as Nuketown 24/7, Domination, and Kill Confirmed) yield Fuel Cans quickly through kills, while looting caches in Casual Battle Royale and Resurgence offers another fast farming route.
4. Is the Mammoth LMG usable in Ranked Play?
No, the Mammoth LMG is not usable in Ranked Play. Activision’s competitive rules exclude LMGs from Ranked, and new-season weapons aren’t added to the approved list.
5. Do I need to own the Season 5 Battle Pass to get Machine of War rewards?
No. The Mammoth LMG is an in-season Machine of War event reward and unlocks through the event track separately from the Battle Pass. The Season 5 Battle Pass weapons are the FG42 and Gremlin, while the Mammoth LMG is tied specifically to the Machine of War event.
