Halo: The Fall of Reach is an animated adaptation of the beloved Eric Nylund novel of the same name, and in many ways the origin story of the Master Chief and Blue Team.

Halo: The Fall of Reach tells the dramatic tale of the origin and intrigue behind the SPARTAN program that propelled characters like the Master Chief and Dr. Catherine Halsey into the pantheon of Halo lore. The story reveals the events that brought Master Chief and Blue Team together, including their Spartan training and their daring mission to strike back at the Covenant during the first days of the deadly alien invasion.
