The plot starts in the year [[2560]]. The [[UNSC Infinity]] has been destroyed by [[Atriox]]'s Banished forces above [[Installation 07|Zeta Halo]].

The Master Chief's suit is reactivated and he boards the warship [[Gbraakon]] and destroys it. He makes his way down to the ring to retrieve [[The Weapon]], whose purpose is to imitate and lock down [[Cortana]]. The Master Chief and the Weapon defeat various Banished forces, before learning of a species called [[Xalanyn|The Endless]] after meeting The [[Harbinger]]. The Harbinger tells him she wants to start the [[Reformation]] so she can find and free her people, who were imprisoned because they can survive the activation of the [[Halo Array]].
