Halo 5: Guardians is a first-person shooter video game developed by 343 Industries and published by Microsoft Studios for the Xbox One. The fifth mainline entry and tenth overall in the Halo series, it was released worldwide on October 27, 2015. The game's plot follows two fireteam of human supersoldier: Blue Team, led by Master Chief, and Fireteam Osiris, led by Spartan Locke. When the former goes absent without leave to track down the artificial intelligence construct Cortana, Master Chief's loyalty is called into question, and Fireteam Osiris is sent to retrieve him.

343 Industries started to plan concepts and objectives for Halo 5 shortly after the release of its predecessor, Halo 4. In late 2012, the team set out goals for the game, including larger campaign and multiplayer areas. Like Halo 4, it uses motion capture for character animation. It features new abilities and character designs, but does not feature any offline capabilities or local networking. It has a game engine that scales its resolution to maintain a frame rate of 60 frames per second.

Halo 5: Guardians is a first-person shooter, with players experiencing most gameplay through the eyes of a playable character. The camera switches to a third-person view for some cinematics and gameplay sequences.

The game preserves many of the core features of the Halo franchise's gameplay experience. Players step into the MJOLNIR powered armor of a Spartan and control that character's actions. MJOLNIR armor provides deflector shields, which diminish whilst protecting the wearer from weapons fire but recharge after a short recovery. Spartans may only carry two personal weapon at a time, but may swap them out at any time for any other weapon they find (including those dropped by slain enemies) and may also carry and fire a crew-served weapon (discarded when the player switches back to a personal weapon). Spartans may also throw grenade and use their weapons for pistol-whipping. Finally, some of the vehicles and their mounted weapons are available for use.

Fireteam Osiris has not been a contender in any CBUB matches.
