Got offered today, the "Golden Gun Glitch", which basically means I will get All weapons unlocked, All perks pro, and killstreaks all unlocked. (At any level)
The way to spot this is of someone has a golden gun and isn't upto prestige 14.
Anyway, If you see anyone with the golden gun and they are not at prestige 14 then report the cheating scumbags!
(Obviously they are too thick to not use the golden camo, and keep their cheating ways a secret)
