The Black Ops 7 Launch Day grind is officially here, and this year, Treyarch has turned things up a notch for Camo Hunters. There are 20 mastery camos to unlock across Campaign, Multiplayer, Zombies, and Warzone, giving players more long-term progression goals than ever before. Each mode features its own unique set of challenges, encouraging players to experience every corner of Black Ops 7 on the road to full mastery.
Zombies makes its grand return yet again, giving players a chance to earn four new mastery camos. With multiple zombie maps to grind on, the hunt is on to eliminate elite zombies & beat the new Easter Eggs. This guide will tell you how to unlock the Doomsteel Mastery Camo in Zombies, the third step on the path to unlocking the Infestation Camo.

The Doomsteel Camo requires players to complete two of the previous mastery camos, as well as the military & special camos, before moving onto the third piece of the Zombies Mastery Camo trail.
To begin, every single gun must have the Golden Dragon Camo unlocked. You can read here on how to do so. It requires players to complete the military camos for each weapon before completing three challenges to unlock the Special Camos, before a final challenge to unlock the camo. Players are required to get 10 kills rapidly 15 times, which is best done using trains. Run in a circular path until you have enough zombies following you, unload every bullet you have, & repeat.
Once you have successfully obtained that camo for every weapon, you'll have to proceed to the Bloodstone Camos. Once you have Golden Dragon Camo for every weapon within a weapon category, there is one challenge per gun that has to be completed to unlock the Camo, which is to get 20 or more consecutive kills without taking damage 5 times. You must repeat this process for all 30 weapons and 9 categories.
Now that you have successfully unlocked the first two mastery camos, you can now focus on the Doomsteel Camo challenges. If you have Bloodstone Camo for every weapon within a weapon category, you'll have a single Challenge yet again to complete. The challenge per weapon is to get 10 Elite Zombie Kills. To review, it requires:
Reaching level 55 to unlock each weapon
Completing the Military Camo Challengers with each weapon
Unlocking each of the three Special Camos by completing challenges for all 30 weapons
Complete the challenge for all 30 weapons to unlock Golden Dragon Camo (Get 10 kills rapidly 15 times)
Complete the challenge for all 30 weapons to unlock Bloodstone Camo (Get 20 or more consecutive kills without taking damage 5 times)
Finally, get 10 Elite Zombie kills to unlock the Doomsteel Camo
The journey for Zombie camos can be long, but in Black Ops 7 Zombies, it clearly has the best Mastery Camos. Onto the final zombie mastery camo: Infestation.
