Want to level up quickly in Call of Duty: Black Ops 3? Then buy some Doritos and Mountain Dew when the game comes out.
Activision has announced that by purchasing Mountain Dew and Doritos and entering their product codes online, Black Ops 3 players can get up to 30 minutes of double XP in Zombies per day. The double XP cannot be earned anywhere else, Activision revealed.
This is not dissimilar to Destiny: The Taken King‘s Red Bull promotional stunt, where buying the energy drink allows players to unlock an exclusive quest.
