While it isn't a new flavor of Mountain Dew Game Fuel this time around, Halo Infinite will be partnering up with another popular energy drink manufacturer for their cross-promotions. Not only will gamers get Double XP in Halo Infinite, just as they could for Call of Duty and previous titles, but QR codes on each can of Monster Energy will also unlock exclusive in-game weapons for Halo Infinite. Because of Halo Infinite being delayed out of 2020, Monster Energy is calling this one a 'Bank Now/Play Later' promotion.

Monster Energy hasn't yet shared what the can designs will be or what "exclusive in-game weapons" will be available through the Snapchat cross-promotion in Halo Infinite. Once we learn more, we'll be sure to update our story accordingly.
