What are black ops 7 bot lobby Challenges? 

 First, you have to complete the BO7 challenges associated with a specific weapon (kills and headshots or shooting while trying to aim). to get the first "gold" camo for that weapon.

 After that, you can unlock gold for all weapons in that particular class. Following that, you proceed to the global mastery camos, which is displayed by everyone in the lobby. It's a badge of honor that says you actually grinded to earn the achievement... You suffered, cried in tears, cried, tried and fought, but you never gave up bo7 codes.

 The biggest change this year is that the Co-op game now offers Mastery Camos. You can earn camo for completing the campaign, not just multiplayer or Zombies. In the past, your progress in completing a campaign didn't count toward the shared camo system. Your campaign play has been fully integrated, and camo has become a status skin that can be used, but not as an add-on or bonus.

 Campaign Mastery Camos

 For for the first time, the campaign is now part of overall camo progression. Take a look at the Campaign Mastery Camos which you can earn.

 Multiplayer Camos

 Multiplayer is a part of the game that lets you meet players sliding, jumping, shooting mid-air and acting as if the laws of physical laws have no impact on them. The challenges in Black Ops 7's camo are a lot like marathons.

 Zombies Mastery Camos

 In Zombies the game, you and your companions are fighting waves of undead. Each map is unique and has unique traps, twists and objectives, so you can relax or sweat it out.

 Warzone Mastery Camos

 Warzone is an intense battle royale in which only the final team standing will win. These four camos are top-tier and will be noticed by everyone in the final circle.
