Halo 5: Guardians (Used Xbox One)

Microsoft is calling Halo 5: Guardians "the greatest evolution in Halo history," and it's easy to see why. The campaign plays out in a galaxy-spanning story that includes three new worlds. You start the game as Spartan Locke, leading a squad of battle-hardened warriors on the hunt for missing Master Chief. Later in the game, you'll play as Master Chief himself. The 4-player co-op experience lets you play with either AI teammates or with friends over Xbox Live. For versus multiplayer, all the intense 4v4 action from past games is represented in Halo 5's Arena Mode - but there's a new way of battling. Warzone is a massive-scale, objective-based multiplayer mode that supports 24-player battles with both friendly and enemy AI, including Spartans, Covenant, and Forerunners.
