At Comic-Con 2015, the studio also dropped the first trailer for Halo: The Fall of Reach, a new animated series arriving with every Limited Edition and Limited Collector’s Edition of Halo 5: Guardians. According to 343, it is a three-act series that “tells the oft-shrouded origin stories of the SPARTAN-II program” and is “set during events both before and after the terrifying Covenant attack on humanity…” It will serve as an introduction to Blue Team, who fall under the command of Master Chief in Halo 5: Guardians.
