This page will contain a complete text and video walkthrough of Halo: Reach, the first-person shooter prequel to the Halo series. Developed by Bungie (in the studio's final go-around with the Halo universe) and published by Microsoft, the game will be released on September 14, 2010.

One of the most highly anticipated games of 2010, if not of all time, Halo: Reach sets the stage for all of the Halo games that have come before by revealing the origin story of the franchise's main character, Master Chief. At the same time, the game chronicles the beginnings of the intergalactic struggle between the human forces, known as the Spartans, and the alien power called the Covenant. The events that lead to the fall of the human colony of Reach are felt throughout the series; the war that players have fought since the franchise's inception began here. Now, finally, players will experience not only the details of the doomed colony's desperate struggle for survival, but also the events that shaped the destiny of the legendary Spartan warrior Master Chief. Told on an epic scale beyond anything ever seen in the series, Halo: Reach is the first, final and indispensable chapter in one of the most popular franchises in the history of video games. Developer Bungie bows out of the series it created with this, its final Halo title, having spared no effort to make Reach the most epic Halo of them all.
