Where the original Halo Wars took place before the events of the main games, Halo Wars 2 picks up after the close of Halo 5: Guardians. The Master Chief's tale is ongoing in another part of the galaxy, leaving the Spirit of Fire crew to repel what Covenant forces they could pre-Combat Evolved, only to be left floating through space after a debilitating explosion forced everyone to retreat into cryo-sleep.

With the crew comprising Captain Cutter, a brand new A.I. named Isabel, a fleet of foot-soldiers, a platoon of Spartans and more, they all awake to find a new, villainous force bearing down on their incapacitated ship. Speaking of A.I., a large part of Halo 4 and 5 has been the onset of "Rampancy"; the process by which A.I. life in the universe eventually loses its cognitive processing abilities, before slowly going insane.
