Halo 5: Guardians is an FPS game developed by 343 Industries.

Set in 2558, 8 months after Halo 4, the plot revolves around two fireteams. Blue Team with Master Chief acting as a commanding officer and Fireteam Osiris led by Jameson Locke. Blue Team goes AWOL in order to find Master Chief's old comrade while Osiris is sent after the Team on a capture and retrieve mission.

Like in previous titles, the players control a SPARTAN, biologically engineered supersoldiers that use the MJOLNIR battle armor. This armor has energy shields that deplete upon receiving any damage but regenerate after a certain amount of time. The players are capable of carrying two firearms at a time, but it is possible to pick up every weapon dropped by the enemy.

Unlike the previous installments where the player could only be followed by NPCs in singleplayer but had the ability to play in a separate co-op mode, Halo 5 takes the concept further and now every of four fireteam members can be controlled by a player. The game does not feature any autonomous features like split-screen on LAN play.
