Halo Infinite is the subject of a number of cross-promotional marketing campaigns with other brands, many of which include exclusive in-game unlocks.
Monster Energy partnered with Microsoft to offer timed double XP bonuses and exclusive in-game content for Halo Infinite as a reward for purchasing Monster Energy products. The following cosmetic items are included in this partnership:
