The campaign includes first-person shooting and driving components and may be played solo or collaboratively (through Xbox Live or split-screen). Cortana is nearing the end of her existence before succumbing to Rampancy, a state in which an AI begins to think itself to death. The main game delves deeply into Master Chief’s relationship with his AI companion, Cortana.
The game foreshadows a new scenario in which Master Chief returns to face his destiny and an ancient awakened evil that threatens all life in the universe. Since the game’s conclusion, he’d been presumed dead or missing in combat by Covenant and UNSC troops. For the first time since 2007’s Halo 3, it sees the return of the surgically enhanced super soldier or “Spartan” Master Chief, John-117, as a playable protagonist.
The plot takes place in the year 2557 in a science fiction environment, four years after the events of Halo 3. It is the first installment of the Reclaimer trilogy. Halo 4 is a first-person shooter in the Halo franchise, and it is the series’ first wholly new game without the involvement of the original developer Bungie Studios.
