Spectrum camo was a reward from pre-ordering from the Microsoft Store. The only way to get it is to purchase the code off of someone who has not used it (Usually going for $100+ on eBay and rising), or if you let someone who has it download your account and put it on your guns for you. Anyone who says that they can give it to you through an "online" lobby is fake and should not be trusted. The camo cannot be given through the online unlockall lobbies as it is not one of the content related items shipped with the disc.
