Call of Duty – Black Ops: How to Get Gold Guns
In Call of Duty: Black Ops for the PC, PS3, Xbox 360, and Wii, you can unlock golden camo for just about any weapon.
In order to unlock golden camo to make your guns gold colored, you’ll need to reach Prestige rank 14, and purchase it for 50,000 credits for each gun you want it on.
Yes, that means you’ll need to level up to level 50 a total of 14 times to unlock the golden camo for your weapons. It will take a lot of time, but if you already play a lot then it shouldn’t matter that much.
There used to be some glitches to unlock this kind of stuff early, but as far as I can tell they have all currently been patched and no longer work.
