=== Plot synopsis ===

{{Spoiler/begin}}

The game begins on [[High Charity]], the mobile capital city of the [[Covenant]]. The former [[Supreme Commander]] of the [[Fleet of Particular Justice]], [[Sangheili Zealot|Commander]] [[Thel 'Vadam]]ee, is on trial before the [[High Council]] for his failure to protect [[Installation 04|Halo]]. Despite his insistence that the [[The Flood|Flood]] hampered his abilities, the [[Hierarchs]] who lead the council, the High [[San'Shyuum|Prophets]] of [[Prophet of Truth|Truth]], [[Prophet of Mercy|Mercy]], and [[Prophet of Regret|Regret]], deem him guilty of failing to protect the Sacred Ring. 'Vadamee is then stripped of his rank and his armor and is branded with the [[Mark of Shame]] by [[Tartarus]], the [[Chieftain of the Jiralhanae]].

The story returns to the disgraced [[Sangheili]] Commander, Thel 'Vadamee, who is given a chance for redemption by the High Prophets of Truth and Mercy by taking up the mantle of [[Arbiter]] and the imminent mortality it entails. The new Arbiter becomes the will of the Prophets, seeking redemption by completing seemingly impossible tasks assigned to him. As his first mission as the Arbiter, 'Vadamee is tasked with the assassination of a [[Sesa 'Refumee|Heretic Leader]], Sesa 'Refumee, who has become disillusioned with the Covenant following the events on Installation 04 and its destruction. 'Vadamee tracks the Heretic Leader through the gas mine where the [[Heretics]] sought refuge, battling the Heretics and the Flood along the way. When the Arbiter finally faces the 'Refumee, he asserts his belief that the Prophets have lied about the [[Covenant religion|Great Journey]]. [[343 Guilty Spark]] appears and corroborates 'Refumee's assertion (both Elites consider Guilty Spark to be an Oracle of the [[Forerunner]]s, the ancient race the Covenant hold as gods). Before 'Vadamee can learn more of the claims, 'Refumee attacks 'Vadamee, and the Heretic Leader is killed. Tartarus then appears to extract the Arbiter and Guilty Spark, further preventing 'Vadamee from learning any further information from Guilty Spark. 'Vadamee departs, not learning what caused the Heretics to betray their sacred oaths to the Covenant.

Returning to SPARTAN-117's story, the ''In Amber Clad'' exits slipspace with the Prophet of Regret unaware that he had been followed. To the surprise of the pursuers, they discover that Regret has led them to another [[Installation 05|Halo Ring]]. Keyes sends John-117 and ODSTs to the surface of Installation 05 to capture Regret while the ''In Amber Clad'' is repaired. In the course of pursuing Regret, John-117 discovers, with the aid of Cortana, that the [[San'Shyuum]]  intends to personally activate Halo, in the belief that it will propel true believers on the [[Covenant religion|Great Journey]]. To buy time to acquire the [[Activation Index]] before the Covenant are able, Keyes orders John-117 to kill the Prophet of Regret, a mission he successfully achieves. Before making his escape, however, High Charity and its [[High Charity Defense Fleet|escort]] arrive and attempt to kill John-117 by glassing the area. He survives by jumping into the lake surrounding the structure in which he encountered Regret. Incapacitated from the shock of the Covenant bombardment, John-117 is last seen being dragged into the depths of the lake by tentacles belonging to a sentient creature.

John-117 is teleported inside of High Charity in the middle of a broadcast by the Prophet of Truth. Upon John-117's arrival, Truth and Mercy flee to the [[Anodyne Spirit|Forerunner Dreadnought]], and formally transfer command of the Covenant Military to the Brutes. Before the prophets make it to the ship, however, they are attacked by the Flood, and Truth leaves Mercy behind to die. Meanwhile, John-117 pursues the Prophets. Throughout his pursuit, he kills many Covenant troops, witnesses the [[Great Schism|conflict between the Sangheili and the Jiralhanae]] and saves a group of Marines. At the same time, the Flood, under the control of the Gravemind crash into [[High Charity]] using the ''In Amber Clad''. John-117 finds Mercy being infected by the Flood, and the Prophet tells the Spartan that Truth is going to Earth to "finish what [[Hierarchs|we]] started." Cortana implores John-117 to pursue Truth, but he is hesitant as his mission to retrieve the Index is not complete. Cortana devises a plan to complete his mission by detonating the crashed ''In Amber Clad'' to destroy the ring if it is activated. This plan, however, requires Cortana to stay on board High Charity. John-117 boards the Dreadnought through an energy conduit before promising Cortana that he will come back for her.

Meanwhile, Thel 'Vadamee is teleported to near Halo's Control Room. There he finds many dead Elites, which he has no doubt were killed by the Brutes. With the help of a few deployed Elites, and sympathetic [[Unggoy]] and [[Mgalekgolo]], he fights his way to meet the [[Special Operations Commander]] [[Rtas 'Vadum]]ee, who is surprised to hear that the Brutes murdered the [[Sangheili Councilor|Councilor]]s. Seeing Tartarus land on Halo's Control Room, the Sangheili fight their way to a {{Pattern|Protos|Scarab}}, where Sergeant Johnson is held. Johnson forcefully initiates an uneasy alliance between the humans and the Elites and takes control of the Scarab. With the combined efforts of Johnson and 'Vadamee, the Scarab breaches the Control Room doors by using the Scarab's main energy cannon, and 'Vadamee enters to confront Tartarus. In the Control Room, Tartarus hears the truth of the Halos directly from [[343 Guilty Spark]]. Still blinded by faith, Tartarus forces Keyes to activate Halo. Many [[Sangheili Zealot|Zealots]] and Councilors aid the Arbiter in his final fight against Tartarus, and eventually after a long and tough fight, manage to kill him. Once Tartarus is defeated, Keyes grabs the Index just in time to stop Halo from firing. However, 343 Guilty Spark says that this has activated a failsafe protocol, causing the Installation to send a signal to the rest of the [[Halo Array]], putting them on standby for remote activation from [[Installation 00|the Ark]].

When playing as the Arbiter, the player's flashlight is replaced with a rechargeable [[active camouflage]] that lasts for ten seconds, giving the player a preemptive advantage on unsuspecting enemies.  

On the damage mechanics, fall damage now has been reduced considerably. The threshold minimum damage has been increased, such as from 3 stories building height will not cause player any damage while on [[Halo: Combat Evolved|the previous game]], it gives the player some damage. The most benefits come from splatter damage as a slight touch from the object now is no longer kill anyone instantly including player (Except some who are designed to be invulnerable). The player now needs more effort to score a splatter kill.
