HALO 4 STORY

HALO THUS FAR
After thirty years of war with the Covenant, humanity finally found victory. The Master Chief, a Spartan super-soldier, and Cortana, an AI construct of unmatched technical sophistication, put an end to the Covenant, the Flood, and the threat of the Halo Array on a remote installation known as the Ark. Now, in the wake of the conflict, the Chief and Cortana drift through space aboard the remains of Forward Unto Dawn, slowly approaching a mysterious artificial world they will soon come to call Requiem.

UNSC INFINITY
A warship unparalleled in human innovation, the UNSC Infinity is easily the largest and most powerful vessel ever employed by Earth. Although it was originally designed to contend with the Covenant, the war's end recommissioned Infinity for peaceful exploration and research—until it discovered the Forerunner world of Requiem and was mercilessly pulled into the maw of the planet. Now, the fate of Infinity and its crew is inexorably tied to that of the Master Chief, as the ending of a 100,000-year story finally takes shape.

SPARTAN-IV
In the wake of the SPARTAN-III project's success, the Office of Naval Intelligence secretly commissioned the activation of yet another project under the direction of CINCONI Admiral Margaret Parangosky: the SPARTAN-IV project. While these assets are now allocated to the UNSC military branch simply dubbed "Spartan," these super-soldiers were handpicked from the field as military veterans who were capable of physical augmentation in order to wear Mjolnir armor, and had also met the litany of prerequisites required to receive title of Spartan.
