Gameplay
Halo 4 is a shooter game, in which players predominantly experience gameplay from a first-person perspective; the game perspective switches to third-person when using certain weapons, armor abilities and vehicles. The player's head-up display (HUD) shows real-time information on the player character's armor system, such as shield status, information on current weapons and armor abilities, and waypoints for goals and objectives. The HUD also has a motion tracker that detects allies, enemies, and vehicles within a certain radius of the player.
The game sees the return of the Covenant as foes, and introduces a new type of enemy called the Prometheans, which are Forerunner constructs. There are three types of Prometheans: Knights serve as leaders of the group and are considered as the deadliest of the Promethean forces; Crawlers are a weaker class which often attack in larger packs; Watchers are deployed by Knights, offer support and have the ability to shield or revive Promethean allies.
Halo 4 features updated versions of many UNSC and Covenant weaponry from previous Halo games, as well as introducing new weapons for the humans, Covenant and Prometheans. The game also features reusable equipment, called armor abilities, which were introduced in Halo: Reach. New armor abilities are autosentry; hardlight shield, which activates a protective barrier similar to a riot shield; Promethean vision, which diminishes environment detail and shows hidden players as silhouettes; regeneration field, which heals all players in close proximity and can emit a short range kinetic blast; and thruster pack, which allows the player to launch themself several feet in a horizontal direction. Returning abilities include active camouflage; jetpack; and hologram, which creates a facsimile of the player running towards a target point. Sprinting returns in Halo 4, however players can now use it independently of their armor ability. New gameplay mechanics introduced to the series include throwing and catching, which has been implemented into the multiplayer game types: Oddball and Grifball.
