The Halo series is one of the most important sets of games in human history if you measure “importance” by how much someone is willing to get in a fist fight with you over the evaluation of videogames. Just as Goldeneye was for the previous generation, Halo set the standard for the kind of games that college students would scream at each other over. In most of these games, you take the role of the Master Chief, a faceless augmented Spartan with the will and the way to shoot his way through virtually every imaginable scenario with his trusty companion Cortana. This simple premise has given over into one of the most complex and impenetrable transmedia storytelling devices, with comics, novels, series and short films that tell the story of the Halo universe and how it responds to the actions of, and around, the Master Chief. Halo 5: Guardians is out next week, so what better time to look back on the long history of this thing that people like? Buckle in for a hardcore, objective ranking of the games of this series from worst to best.
