Halo is one of the most popular video games in the industry today. The first-person shooter follows Master Chief, a Spartan who battles against the alien invaders, the Covenant and the Flood. Although it is a booming franchise, the Halo universe is largely unexplored outside of this character. Dark Horse Comics attempts to remedy this problem with their new comic miniseries. A lead-in to the new Halo mobile game, Halo: Spartan Assault, Halo Initiation follows Commander Sarah Palmer as she undergoes a secret United Nations Space Command (UNSC) Spartan program. Without the Master Chief, the Covenant or the Flood supporting the story, Halo Initiation branches away from the video games to open a new world for their fans.
