Microsoft's biggest franchise is Halo, a series created by Bungie and now developed internally at 343 Industries. The sci-fi series primarily about an ongoing battle between humanity and the alien Covenant has a long and storied past, and the franchise has seen numerous popular and beloved entries over the years.

With Halo Infinite set for release in December, we're looking back at the Halo series overall and ranking the mainline FPS franchise. This list covers only the main FPS games, not offshoots like Spartan Strike or the arcade game Fireteam Raven. We're also not including the Halo Wars series, though it's great for those who want more story context on Infinite. And while Halo: The Master Chief Collection is absolutely the best way to play Halo in 2021, it's also not featured on this list because it is a compilation package instead of one game. You can also sign up for Game Pass Ultimate to play every mainline Halo game as well as numerous spin-offs.
