Treyarch announced today that double weapon experience is now live for Call of Duty: Black Ops 2. The weapon XP event started today and will continue until Monday. The developer stated earlier that the double weapon experience bonus is due to the fact that the Playstation 3 and PC version of the game received the Revoloution DLC for the first time.
What are you waiting for? Go play some Black Ops 2 and get awarded with double weapon XP.
