Halo 4/Setting and characters

Halo 4 takes place in a futuristic science fiction setting in the year 2557, four years after the events of Halo 3.[20]

Backstory details that hundreds of thousands of years before the modern era, humans were one of several interstellar civilizations.

Following a war with the parasitic Flood, the humans came into conflict with the Forerunners, a powerful race that upheld a policy of benevolent shepherding of other races known as the Mantle of Responsibility.

After centuries of war the Forerunners defeated the humans and stripped them of their technology and empire.

The Forerunners soon fought the Flood themselves; after exhausting every other strategic option available to them, the Forerunners activated weapons of mass destruction known as the Halo Array.

The Array's firing killed all sentient life in the galaxy to deprive the Flood of their food.

Life that the Forerunners cataloged was then reseeded throughout the galaxy.[21][22]

In the 26th century, humanity came under attack by the Covenant, an alien collective of species that worship the Forerunners as gods.[23]

The human supersoldier Master Chief Petty Officer John-117 and his artificial intelligence companion Cortana, were instrumental in stopping the Halos from being activated, sterilizing the Flood outbreak before they could menace the galaxy once again, and defeating the Covenant resulting in the end of the war.[23]

At the end of Halo 3, Chief and Cortana were left stranded in unknown space aboard the remains of the vessel Forward Unto Dawn.[24] [[Category:A]]
