· Desert Eagle (Reach level 55) · M1014 (50 kills and 100 headshots for all shotguns) · Dragunov (100 kills and 150 headshots with all Sniper rifles) · Mini-Uzi (150 kills and 150 headshots with all SMGs) · AK-47 (150 kills and 150 headshots with all assault rifles excluding the MP44, which only requires the headshots) · M60E4 (150 kills and 150 headshots with all LMGs)
There are six weapons that can equip the Golden Camouflage. It is acquired by completing all the challenges for their respective weapon class, except for the Gold Desert Eagle, which is achieved when rank 55 is reached. This has no beneficial features over other camouflages, beyond their exclusivity. The player can check their progress for each weapon by going to barracks, selecting Challenges and view the type of gun they are trying to get Gold Camouflage for.
Gold Camouflage was rumored to appear in Call of Duty: Modern Warfare 2 but didn't, although a golden Desert Eagle can be found in the game files. This Desert Eagle, however, is modeled after the one in Call of Duty 4, as can be most easily noticed by the lack of the under-barrel laser, or that it cannot have any attachments, unlike the normal Desert Eagle in the game.
Gold Camouflage is available in Call of Duty: Black Ops, and is available after the player has Prestiged 14 times. With Gold Camouflage, most metallic components of the gun are covered in gold plating, while wooden and plastic components are replaced with black, synthetic materials. This has the possible effect of obscuring emblems on certain guns. Golden camouflage is available for every primary weapon, and can also affect certain attachments as well. In addition to these, shotgun shells will also appear golden.
To use Gold Camouflage for any weapon, the player must be at least 14th Prestige and be willing to pay 50,000 per Gold Camouflage. However, while it is not obtainable in Combat Training, it is automatically unlocked in Split Screen. The player can set the class loadouts in custom Private Matches to have golden camouflage on their primary weapons.
To attain the Gold Camouflage for a weapon the player must complete a list of challenges in order with that gun. These challenges unlock other camouflages, and are seen by personalizing the weapon in Create-a-Class or via Barracks. However, the challenges for each gun class varies and are not all similar. For example, where getting 100 headshots on an assault rifle would unlock Kryptek: Typhon, the same challenge on sniper rifles requires the player to obtain 250 one-shot kills. In addition, some weapons in their own tier may have different challenges, examples being the FHJ-18 AA and RPG, both being launchers but requiring aircraft destroyed and kills for the first nine challenges, respectively.
The first nine challenges require a set amount of kills, headshots, one-shot kills or aircraft destroyed, depending on the weapon type. The amount is larger by each challenge. Once they have been completed, the remaining challenges' details are visible and can be progressed through. Once all the challenges have been completed and all camouflages have been unlocked, the player will have gained access to Gold Camouflage. If the player unlocks Gold Camouflage for all weapons in a weapon category, then they will acquire Diamond camouflage for every weapon in that class.
Gold Camouflage reappears in Call of Duty: Ghosts. This time, it is unlocked by getting all the weapon camos (except the Body Count, Kiss of Death, War Cry and DLC camos) on that specific gun, similar to Call of Duty: Black Ops II.
Like other camouflages, it is only compatible with most primary weapons. However, a patch on June 3rd, 2014 released Golden variants of the PDW and Combat Knife as well (the latter didn't have any camouflage in Ghosts, although it is a primary weapon). The Gold Knife is available at Prestige 5 and has a Fast Melee, while the Gold PDW is accessible at Prestige 10 and has a Automatic Fire mode and a 20-round magazine.
In Call of Duty: Modern Warfare 3, the gold camouflages covers most, if not, all of the weapon, whereas other camouflages will leave parts of the weapon plain, such as the magazine, stock, and the scopes on Sniper Rifles.
In Call of Duty: Modern Warfare 3, shotgun shells fired from a Model 1887 and KSG 12 with Gold Camouflage will be gold.
In Call of Duty: Black Ops II, the Gold and Diamond camouflages tint the scope on a Sniper Rifle.
