Exclusivity is one of the most frustrating aspects of the gaming industry for consumers. Many iconic franchises, like The Legend of Zelda, Gears of War, and Super Mario, are unavailable to PlayStation players, which can leave people feeling left out. One other series that has eluded the blue brand is the sci-fi first-person shooter Halo. Led by its protagonist, Master Chief, the Halo games have been a cornerstone of the FPS genre since Halo: Combat Evolved hit stores in 2001.
