How to Unlock Call of Duty Black Ops II Diamond Camo: The Ultimate Mastery Guide

Master the grind with our comprehensive guide on how to unlock the iconic Call of Duty Black Ops II diamond camo for every weapon class in multiplayer.

For many veteran players, the pursuit of the Call of Duty Black Ops II diamond camo represents the pinnacle of the 2012 multiplayer experience. Unlike standard skins that you can simply purchase, this prestigious finish serves as a badge of honor, signaling to every opponent in the lobby that you have mastered an entire suite of weaponry. Earning the Call of Duty Black Ops II diamond camo requires more than just luck; it demands a calculated grind through headshots, bloodthirsties, and specific technical challenges across every gun in a specific category.

What Makes Diamond Camo Iconic?

Introduced as a "hidden" tier above the standard Gold Camouflage, the Diamond finish in Black Ops II fundamentally changed how players approached weapon progression. Visually, it is a striking combination of a solid gold base studded with brilliant-cut diamonds. This aesthetic doesn't just cover the body of the gun; it often extends to the iron sights, providing a bright, high-contrast view that some players find helpful, while others find it a bit of a visual distraction.

Community reports often highlight that the Diamond skin is more than just a cosmetic upgrade. It was the first time the Call of Duty franchise implemented a "Mastery" camo that required completing an entire weapon class. This set the stage for later iterations like Solar, Dark Matter, and Damascus. In Black Ops II, the Diamond skin is purely a multiplayer reward and does not appear in the Zombies mode unless modified or through specific glitches, making it a true symbol of competitive dedication.

The Core Requirements for Unlocking Diamond

To unlock Diamond for any weapon, you must first unlock the Gold Camouflage for every single weapon within that specific category. If you want Diamond Assault Rifles, every AR in the base game must reach Gold status.

The path to Gold (and subsequently Diamond) is divided into two main phases: the Headshot/One-Shot Kill phase and the Technical Challenge phase.

Phase 1: The Kryptek and Carbon Grind

For most weapons (Assault Rifles, SMGs, LMGs, and Pistols), you must record 100 headshots. For Sniper Rifles and most Shotguns, the requirement is 250 One-Shot One-Kill medals. Once these are completed, you unlock the "Technical" challenges.

Phase 2: Technical Challenges

After completing the initial 100 headshots or 250 one-shots, you must complete five specific challenges to unlock Gold:

Carbon Fiber: Get 10 Longshot medals (varies by class).
Cherry Blossom: Get 150 kills with no attachments equipped.
Art of War: Get 150 kills with no perks equipped.
Ronin: Get 20 double kill medals.
Skulls: Get 10 Bloodthirsty medals (5 kills without dying).

Weapon Category Breakdown

Unlocking the Call of Duty Black Ops II diamond camo is a different experience depending on which class you are tackling. Some classes, like SMGs, are generally considered easier due to the fast pace of play, while the Specials or Launchers can be incredibly frustrating.

Weapon Category	Base Weapons Required	Primary Challenge Type	Difficulty Rating
Assault Rifles	9	Headshots	Medium
Submachine Guns	6	Headshots	Easy
Light Machine Guns	4	Headshots	Medium
Sniper Rifles	4	One-Shot Kills	Hard
Shotguns	4	One-Shot / Headshots	Medium
Pistols	5	Headshots	Medium
Launchers	3	Aerial Destructions	Hard
Specials	3	Unique Medals	Very Hard

Assault Rifles and SMGs

The Assault Rifle class is the most time-consuming simply because it contains the highest number of weapons. You will need to grind through the MTAR, Type 25, SWAT-556, FAL OSW, M27, SCAR-H, SMR, M8A1, and the AN-94.

For SMGs, the process is faster. You only need to finish the MP7, PDW-57, Vector K10, MSMC, Chicom CQB, and Skorpion EVO. Player experience suggests that the Chicom CQB is often the "bottleneck" for this category due to its burst-fire nature.

The Peacekeeper and DLC Exceptions

A common point of confusion regarding the Call of Duty Black Ops II diamond camo involves the Peacekeeper SMG, which was introduced in the Revolution DLC pack. Because not every player owns the DLC, Treyarch implemented a fair system for mastery.

Scenario	Requirement for Diamond SMGs	Does it include Peacekeeper?
You only own the base game	Gold on all 6 base SMGs	No
You own the Revolution DLC	Gold on all 6 base SMGs	No (to get Diamond on base guns)
You want Diamond on the Peacekeeper	Gold on all 6 base SMGs + Gold on Peacekeeper	Yes

Essentially, the Peacekeeper is an "add-on." You do not need to touch it to get Diamond for your MP7 or MSMC. However, if you want that shiny diamond finish on the Peacekeeper itself, you must complete the entire SMG category first.

Strategies for the Launcher and Special Categories

The Launchers (SMAW, FHJ-18 AA, and RPG) and Specials (Assault Shield, Ballistic Knife, and Crossbow) are the most unique grinds in the game. Unlike firearms, their challenges are specific to their utility.

Launcher Challenges

The FHJ-18 AA is particularly notorious because it can only lock onto scorestreaks. You cannot get kills with it. You are entirely dependent on the enemy team calling in UAVs, Hunter Killer Drones, and Dragonfires.

Special Challenges

The Assault Shield requires you to get kills by bashing enemies, which is a slow and dangerous process. Community reports suggest playing in Hardcore modes to make the Ballistic Knife and Shield kills more consistent, as health is lower and enemies are less likely to survive the initial impact.

Special Weapon	Key Challenge	Pro Tip
Assault Shield	100 Bashes / 25 Kills with no perks	Use Concussion grenades to stun enemies before bashing.
Ballistic Knife	100 Kills / 2 Bloodthirsties with only the knife	Stay in tight corridors and use the "Scavenger" perk.
Crossbow	100 Kills / 1 Double Kill with every bolt	Use the Tri-Bolt attachment to increase hit probability.

XP Rewards and Progression

While the Call of Duty Black Ops II diamond camo itself does not grant a massive lump sum of XP upon the final unlock, the journey to get there is incredibly lucrative for your Prestige level. Each camo unlock provides a small boost, and the "Mastery" calling cards associated with each weapon provide significant chunks of experience.

Technically, if you calculate the XP from the 100 headshots, the subsequent technical camos, the Gold unlock, and the associated Marksman and Mastery challenges, a single weapon can net you upwards of 15,000 to 20,000 XP. Multiplying this across an entire category like Assault Rifles can catapult a player through several levels in a single afternoon.

Tips for Grinding Diamond Faster

If you want to maximize your efficiency while hunting for the Call of Duty Black Ops II diamond camo, consider these community-vetted strategies:

Play Free-for-All for Headshots: In Free-for-All, every player you see is a target. This increases the frequency of engagements and allows you to "flank" camping players for easy headshots.
Hardcore for Weak Weapons: Weapons like the SMR or the SVU-AS can be frustrating in Core. In Hardcore, these are almost always one-shot kills, making the "One-Shot Kill" or "Headshot" medals much easier to obtain.
The "No Perk/No Attachment" Combo: Do not do these challenges separately. Once you unlock the technical tier, clear your entire class. Equip no perks and no attachments simultaneously. This allows you to progress both the "Cherry Blossom" and "Art of War" camos at the same time, cutting your grind in half.
Bloodthirsties (Skulls Camo): This is often the hardest challenge. Don't play overly aggressive. Find a high-traffic area, get two kills, and then rotate to a different position. Staying in one spot will lead to the enemy seeking revenge with C4 or grenades.
Shock Charges and Concussions: For the Assault Shield and Crossbow, utility is your best friend. A shocked enemy is a stationary target, making it much easier to land a crossbow bolt or a shield bash.

Evolution of Diamond Camo

The Diamond camo has appeared in numerous Call of Duty titles since its debut in Black Ops II. However, many players still consider the original version to be the most aesthetically pleasing.

Game	Diamond Unlock Criteria	Visual Style
Black Ops II	All Gold in Category	Gold base with studded diamonds
Advanced Warfare	All Camos for one weapon	Full diamond encrusted
Black Ops 4	All Gold in Category	Reactive (changes color with kills)
CoD Mobile	10 Kills in 100+ Matches	Gold and Diamond pattern

In Call of Duty: Mobile, the requirement shifted significantly, requiring players to get a certain number of kills in over 100 matches after unlocking Gold. This makes the mobile version a test of endurance rather than a test of specific skill-based challenges like the original Black Ops II version.

Conclusion

Unlocking the Call of Duty Black Ops II diamond camo remains one of the most rewarding achievements for fans of the series. It represents a time when mastery was earned through specific gameplay feats rather than seasonal battle passes. Whether you are revisiting the game for nostalgia or playing on backward-compatible platforms, the grind for Diamond is a journey through the mechanics of every weapon, forcing you to become a more versatile and skilled player.

By following the strategies of combining challenges and utilizing the right game modes for each weapon class, you can drastically reduce the time spent in the "Carbon Fiber" phase and move straight into showing off your glittering arsenal in the winner's circle.

Frequently Asked Questions

Does the Peacekeeper count toward Diamond SMGs?

No, the Peacekeeper is not required to unlock the Call of Duty Black Ops II diamond camo for the base submachine guns. However, you must have Gold on all base SMGs before you can unlock Diamond for the Peacekeeper itself.

Why didn't I get XP when I unlocked Diamond?

Technically, the Diamond camo is a "hidden" reward. While you receive XP for the final Gold camo and the challenges leading up to it, the Diamond unlock itself does not trigger a specific XP reward. The value lies in the prestige and the completion of the weapon category's mastery.

What is the fastest way to get headshots in Black Ops II?

The most effective way to get headshots for the Call of Duty Black Ops II diamond camo is to play Free-for-All or Team Deathmatch on small maps like Nuketown 2025 or Hijacked. Aim slightly above center mass and allow the natural recoil of the gun to kick the final bullet into the head. Using the Laser Sight attachment for better hip-fire accuracy can also result in accidental headshots during close-quarters scrambles.
