The fifth numbered entry in the Halo franchise has been rated “T for Teen” by the ESRB, Gamesradar discovered today. All previous Halo titles — with the exception of Halo Wars, Spartan Assault and Spartan Strike, have been rated “M for Mature”.
The content descriptors reveal the game will feature blood, mild language, violence. It appears the violence in Halo 5 has been toned compared to its predecessors; its official rating summary mentions occasional blood-splatter effects, while Halo 4‘s lists “Large blood-splatter effects” and describes a gory scene. You can read the full rating summary for more detail.
Halo 5 Rating Summary:
This is a first-person shooter in which players assume the role of a super soldier (Locke) searching for a missing character. Players use pistols, machine guns, grenade launchers, and futuristic weapons to kill alien and human enemies in frenetic combat. Battles are highlighted by realistic gunfire, explosions, and occasional blood-splatter effects. Characters can also use “assassinations” to kill characters by snapping their necks, or by stabbing them with bladed weapons. The word “a*s” appears in the dialogue, as well as occasional taunts/insults (e.g., “I have copulated…with your genetic progenitors!”; ‘Your father was a filthy colo and your mother was a hole in the wall!’)
Halo 5: Guardians launches on October 27, 2015, exclusively for Xbox One.
