Halo is a pioneer of first person-shooter gunplay on consoles, and it's memorable stories, characters, and multiplayer make it one of the most recognizable franchises in gaming history.
While Halo 5's story got a mixed reception, its multiplayer is still incredibly fun. If you're itching for the classic Halo games, they're available through Halo: The Master Chief Collection. The first four games, in addition to Reach and ODST, are included in this single package.
