The aliens, in turn, choose from such a list: the Bugai Chief, the Arbiter and the Prophet of Sorrow. People have a choice of: James Cutter, Sergeant Forge, and Professor Anders. They have 3 of their own leaders to choose from. The usual UNSC and Covenants will become the playable parties to the conflicts. It is impossible to take control of this race in single battles, but they have their own units among aviation. In the course of the story, locations will change in several dimensions with the ultimate goal of finding the ancient race of Forerunners. The ship's captain, James Cutter, dispatches a squad of warriors on a reconnaissance mission on the surface. Starting two decades before Halo: Combat Evolved, the Spirit of Fire spacecraft is sent by the UNSC to investigate and disrupt the Covenant's plans in Harvest, the planet where humanity first encountered an alien race. Fans will appreciate the additions to the complete history of the UNSC (United Nations Space Command) and Covenant war, and people not familiar with the series have the opportunity to understand the plot without going through the previous parts, made in the shooter genre.
