Halo 3 is a shooter game where players primarily experience gameplay from a first-person perspective. Much of the gameplay takes place on foot, but also includes segments focused on vehicular combat. The balance of weapons and objects in the game was adjusted to better adhere to the "Golden Triangle of Halo": these are weapons, grenades, and melee attacks, which are available to a player in most situations. Players may dual-wield some weapons, forgoing the use of grenades and melee attacks in favor of the combined firepower of two weapons. Many weapons available in previous installments of the series return with minor cosmetic and power alterations. Unlike previous installments, the player's secondary weapon is visible on their player model, holstered or slung across the player's back.
Halo 3 introduces "support weapons", which are cumbersome two-handed weapons that slow the player, but offer greatly increased firepower in return. In addition to weapons, the game contains a new class of gear called equipment; these items have various effects, ranging from defensive screens to shield regeneration and flares. Only one piece of equipment can be carried at a time. The game's vehicular component has been expanded with new drivable and AI-only vehicles.

After the events of the comic tie-in Halo: Uprising, the Master Chief crashes in eastern Africa, where he is found by Johnson and the Arbiter. The Chief, Johnson, and company fight Covenant in the jungle and arrive at a UNSC outpost. Here, Keyes and Lord Hood plan a final effort to stop the Covenant leader, the High Prophet of Truth, from activating a Forerunner artifact uncovered outside the ruins of the city of New Mombasa. The Chief clears anti-air Covenant defenses so Hood can lead the last of Earth's ships against the Prophet, but Truth activates the buried artifact, creating a slipspace portal which he and his followers enter. A Flood-infested ship crash-lands nearby; Elite forces arrive and vitrify Flood-infected areas of Earth, stopping the threat. Following a message Cortana left aboard the Flood ship, the Chief, Arbiter, Elites, Johnson, Keyes and their troops follow Truth through the portal. Joining them is 343 Guilty Spark, who aids the Chief as he has no function to fulfill after the destruction of his ringworld.
Traveling through the portal, the humans and Elites discover an immense artificial structure known as the Ark, far beyond the edges of the Milky Way galaxy. Here, Truth can remotely activate all the Halos. The Flood arrive aboard High Charity in full force, beginning to infest the installation. Truth captures Johnson, as he needs a human to use Forerunner technology. Keyes is killed attempting a rescue, and Johnson is forced to activate the rings. Gravemind forges a truce with the Chief and Arbiter to stop Truth. The Arbiter, Master Chief, and Flood forces arrive and overwhelm Truth's guards, rescuing Johnson and halting the installations' activation. After the Arbiter kills Truth, Gravemind turns on the Chief and Arbiter.
The Chief, Arbiter and Guilty Spark discover that the Ark is constructing another Halo to replace the one that the Chief previously destroyed. The Chief decides to activate this Halo; the ringworld would eliminate the Flood infestation on the Ark while sparing the galaxy at large from destruction. To activate the ring, the Chief rescues Cortana, who has the Activation Index of the destroyed Halo, from High Charity and destroys the city. Arriving on the new Halo, Cortana warns that Gravemind is trying to rebuild itself on the ring. The Chief, Arbiter, and Johnson travel to Halo's control room to activate the ring. Guilty Spark explains that because the ring is not yet complete, a premature activation will destroy it and the Ark. When Johnson ignores his warning, Guilty Spark fatally wounds him to protect "his" ring. The Chief destroys Guilty Spark, activates the ring, and escapes the ring's self-destruction on the UNSC frigate Forward Unto Dawn. However, the force of Halo's blast causes the slipspace portal to collapse, resulting in only the front half of Forward Unto Dawn, carrying the Arbiter, making it back to Earth.
A memorial service is held on Earth for the fallen heroes of the Human-Covenant war, during which the Arbiter and Lord Hood briefly exchange words regarding the fallen Master Chief. After the memorial service, the Arbiter and his Elite brethren depart for their home planet, Sanghelios. Meanwhile, the rear half of the Forward Unto Dawn drifts in unknown space. Cortana drops a distress beacon, but acknowledges it may be many years before they are rescued. The Chief enters cryonic sleep, telling Cortana to "wake me, when you need me." If the game is completed at the Legendary difficulty level, the scene continues to show the piece of Forward Unto Dawn drifting towards an unknown planet, revealed in the sequel to be known as "Requiem", the primary setting of the campaign of Halo 4.

Bundled with seven of the most popular multiplayer maps in Halo history ready for Xbox Live, Halo: Anniversary includes a bounty of new features including cooperative play over Xbox Live, Achievements, new challenges, and new fiction to uncover.

The game opens just following the events of Halo: Reach, as the Pillar of Autumn exits slipspace near a mysterious ring-shaped space station, called "Halo" by the enemy in the game, the Covenant. A Covenant fleet attacks and heavily damages the Pillar of Autumn. Captain Keyes initiates "The Cole Protocol, "a procedure which destroys all navigation data and is designed to prevent the Covenant from learning the location of Earth. Master Chief and Cortana fight their way to an escape pod, where they eject from the ship along with a group of Marines. As they fly away they can see Keyes attempting to crash land Pillar on Halo.

Master Chief and Cortana are the only survivors of their pod's crash landing, but they soon contact other survivors and help collect them into a fighting force. The survivors tell them that Keyes survived the Pillar of Autumn's crash landing, but has been captured by the Covenant and is being held aboard the Covenant ship Truth and Reconciliation. Master Chief and a force of Marines board the ship and rescue Keyes, who orders Master Chief to beat the Covenant to Halo's control center and to discover Halo's purpose. Master Chief and Cortana travel to a map room called the Silent Cartographer, which leads them to the control room. There, Cortana enters the systems and, discovering something urgent, suddenly sends Master Chief to find Captain Keyes while she stays behind. Keyes was searching for what he believed was a cache of powerful weapons, but when he reaches his position Master Chief finds only signs of a battle and a recording revealing they have accidentally released the Flood, a parasitic alien race capable of spreading itself by infesting other sentient life-forms.

The release of the Flood prompts Halo's AI monitor, 343 Guilty Spark, to recruit Master Chief in retrieving the Index, a device that will activate Halo and prevent the Flood from spreading beyond the facility. After Master Chief retrieves and prepares to use the Index, Cortana re-appears and warns him against the activation. She has discovered that Halo's defense system is a weapon designed to kill all sentient life in the galaxy, which will deny the host bodies the Flood requires to spread, a revelation which Guilty Spark confirms.

Faced with this information, Master Chief and Cortana decide to destroy Halo to prevent its activation. While fighting the Flood, the Covenant, and Guilty Spark's Sentinels, Cortana discovers that the best way to accomplish this is to cause the crashed Pillar of Autumn to self-destruct. However, Captain Keyes' authorization is required to destroy the Autumn, forcing the Chief and Cortana to return to the now-Flood-infested Truth and Reconciliation to search for him. By the time they reach Keyes, however, he has been infected beyond the point of no return by the Flood. Master Chief retrieves Keyes' neural implants directly from his brain and retreats to the Autumn, where Cortana activates the ship's self-destruct sequence. However, 343 Guilty Spark reappears and deactivates the countdown, discovering the record of human history in the process. Master Chief manually destabilizes the Pillar of Autumn's fusion reactors, and he and Cortana narrowly escape the destruction of the ring via a fighter. Cortana scans nearby space and finds that they are apparently the only survivors. Cortana justifies the sacrifices of the other humans on Halo, stating that they had no choice due to the threat posed by Halo, the Covenant and the Flood. Cortana believes it's over but the Master Chief tells her that they're just getting started.

In a brief post-credits scene, 343 Guilty Spark is seen fleeing Halo's destruction and into the unknown of deep space.
