Across Black Ops 7 Season 6, Camo Costume Party offers 36 weapon-class challenges divided equally among Co-Op and Endgame, Multiplayer, Zombies, and Warzone. Each mode provides one task for every weapon class; completing them grants event camos, four animated mastery camos, and the new Arcblade melee weapon.
Quick answer: Complete any 9 challenges to unlock the Arcblade. Clear all 9 in a single mode for that mode’s animated mastery camo, and finish all 36 before October 8 at 10 AM PT for the secret completion camo.
How the event is structured
The event sits under the Events tab and splits into four mode tabs. Every tab contains one challenge for each of the nine weapon classes: Assault Rifles, SMGs, Shotguns, LMGs, Marksman Rifles, Sniper Rifles, Pistols, Launchers and Specials, and Melee.
A mode challenge rewards 2,500 XP and applies that mode’s camo only to the matching weapon class. For instance, completing the Multiplayer shotgun task places Gray Matter on every shotgun, but leaves your other guns unchanged. Once all nine tasks for a mode are complete, you get its animated mastery camo and 10,000 XP; that mastery camo can be equipped on any weapon.
| Mode | Class Camo | Mastery Camo |
|---|---|---|
| Co-Op & Endgame | Undergrowth | Gravebloom |
| Multiplayer | Gray Matter | Grubs |
| Zombies | Zombie Mai Tai | Malignant |
| Warzone | Patchwork | Death Row |
The nine challenges needed for the Arcblade do not have to come from the same tab. If you only want the weapon, pick the easiest objectives across all four modes rather than committing to one mastery track.
Co-Op and Endgame challenges (Undergrowth and Gravebloom)
These challenges lean heavily on Endgame systems such as Guild Tech enemies, Combat Rating, Fear enemies, and wingsuiting, so treat this as the Endgame tab. Clear all nine to earn the animated Gravebloom camo.
| Weapon Class | Challenge |
|---|---|
| Assault Rifles | Eliminate 75 Guild Tech enemies with Assault Rifles |
| SMGs | Score 500 eliminations using an SMG introduced in Season 1 or any later season. |
| Shotguns | Get 10 kills with a Shotgun without taking damage, 15 times |
| LMGs | With LMGs, reach 300 eliminations while Combat Rating is at least 40. |
| Marksman Rifles | Use Marksman Rifles to take down 25 Special or Elite enemies. |
| Sniper Rifles | Equip a Sniper Rifle and score 100 Critical Kills against Fear enemies. |
| Pistols | Kill an enemy with a Pistol shortly after wingsuiting, 15 times |
| Launchers & Specials | Get a kill with a Launcher or Special Weapon while airborne, 50 times |
| Melee | Get 75 Critical Kills with Melee Weapons |
Plan around the SMG task first. Its 500 eliminations require an SMG released in Season 1 or later, meaning launch-era weapons will not advance the counter.
Multiplayer challenges (Gray Matter and Grubs)
This is the most straightforward set. Most objectives happen during normal play, with two tied to specific playlists. Complete all nine to unlock the animated Grubs camo.
| Weapon Class | Challenge |
|---|---|
| Assault Rifles | In T.E.D.D. Trials, eliminate 100 enemies with Assault Rifles. |
| SMGs | Get 50 hipfire kills with SMGs |
| Shotguns | Get 3 kills without dying, 10 times, with a Shotgun |
| LMGs | With an LMG, achieve five kills before dying on three separate occasions. |
| Marksman Rifles | Get 2 kills without taking damage with a Marksman Rifle, 3 times |
| Sniper Rifles | Get 3 headshots in a single match with a Sniper Rifle, 5 times |
| Pistols | While a Suppressor is equipped on a Pistol, get 30 eliminations. |
| Launchers & Specials | Get 15 eliminations in Hordepoint with Launchers or Special Weapons |
| Melee | Get 5 Objective Kills with Melee Weapons |
The Assault Rifle task sends you into T.E.D.D. Trials, while the Launcher task uses Hordepoint. Since Hordepoint makes objective eliminations easiest, queue there for the Melee task too and progress on both lines together.
Zombies challenges (Zombie Mai Tai and Malignant)
Zombies is the heaviest grind in the event, with several 500-kill counts and layered conditions. Clearing all nine unlocks the animated Malignant camo.
| Weapon Class | Challenge |
|---|---|
| Assault Rifles | Get 500 eliminations with Assault Rifles while Jugger-Nog and Speed Cola are active |
| SMGs | Get 500 eliminations with an SMG in Rogue Run |
| Shotguns | During one T.E.D.D. Trial, get 75 kills with a Shotgun. |
| LMGs | Get 30 kills with an LMG without reloading, 10 times |
| Marksman Rifles | Get 500 kills with a Marksman Rifle from the Mystery Box |
| Sniper Rifles | Eliminate 4 Elite Zombies with a Sniper Rifle |
| Pistols | Get 300 eliminations with a Pistol in Cursed |
| Launchers & Specials | Get 100 kills with Legendary Rarity Launchers or Special Weapons |
| Melee | Use a Pack-a-Punch Level III Melee Weapon to score 250 kills. |
Prepare each run around its required setup. The Marksman Rifle has to come from the Mystery Box; Pistol kills count only in Cursed; and every Assault Rifle kill must occur while Jugger-Nog and Speed Cola are active. The Shotgun objective requires 75 kills during one T.E.D.D. Trial, making it a single concentrated run instead of a grind across multiple attempts.
Warzone challenges (Patchwork and Death Row)
Warzone carries the smallest numbers in the event, with several challenges finished in a match or two. Complete all nine to receive the animated Death Row camo.
| Weapon Class | Challenge |
|---|---|
| Assault Rifles | Get 25 eliminations with Ground Loot Assault Rifles |
| SMGs | Get a kill with an SMG before the 3rd circle, 25 times |
| Shotguns | Get 10 kills with a Shotgun while in the Top 10 |
| LMGs | Get 2 kills with an LMG without reloading, 5 times |
| Marksman Rifles | Kill 15 enemies with a Marksman Rifle without an Optic equipped |
| Sniper Rifles | Get 5 headshots with Sniper Rifles |
| Pistols | Kill a Bounty Target with a Pistol |
| Launchers & Specials | Get 5 kills while moving with Launchers or Special Weapons |
| Melee | Get a kill with a Melee Weapon shortly after switching weapons, 3 times |
Every objective here stays at 25 or below, and the Ground Loot Assault Rifle task favors entering without a loadout. If reaching the Arcblade is your goal, this tab offers the quickest set of easy challenges.
Unlocking the Arcblade and the final mastery camo
The Arcblade melee weapon unlocks after you complete any 9 challenges, in any combination of modes. Because the requirement ignores which tab a challenge comes from, mixing the easiest objectives across Warzone and Multiplayer is the quickest route to the weapon.
The event’s final reward is a secret mastery camo that requires completing all 36 challenges across every mode. Its appearance stays hidden until you near completion. You’ll know each step landed when the class camo appears on that weapon class, when a mode’s animated camo becomes equippable on any gun after nine clears, and when the Arcblade shows up in your melee loadout.
Event end date and what stays available
The event started at 9 AM PT on September 17 and lasts 21 days, closing Thursday, October 8 at 10 AM PT. All nine camos are event cosmetics limited to this period, so complete any desired tasks before the event closes. The Arcblade remains obtainable afterward through an Armory Unlock, meaning missing the deadline does not permanently lock away the weapon.
