Ubisoft has announced a partnership with Monster Energy around Assassin's Creed: Origins where players can potentially get DLC when they buy one of the energy drinks.

More than 500 million Monster Energy drink cans globally will carry Assassin's Creed: Origins branding, with the cans starting to show up in stores now. This makes it one of Ubisoft's "largest retail promotion partnerships" ever.
