Halo Games in Chronological Order: Master Chief’s Epic Saga from Beginning to End

Traversing the Halo universe chronologically offers a unique perspective on humanity’s struggle against overwhelming odds and ancient mysteries.

The Definitive Halo Timeline: Playing Through the Decades of War

The Halo franchise stands as one of gaming’s most influential sci-fi epics, spanning multiple games across various time periods in its richly detailed universe. While most fans experienced the saga as it released, playing through the series chronologically delivers a cohesive narrative journey following humanity’s desperate struggle against the Covenant, the discovery of ancient Forerunner technology, and the ongoing threats to galactic civilization.

For those looking to experience Master Chief’s adventures (and beyond) in proper story order, this comprehensive timeline organizes all Halo games according to when their events occur in the fictional chronology, rather than by release date.

The Early Human-Covenant War (2531 CE)

Halo Wars

Developer: Ensemble Studios
Release: February 2009
Platforms: Xbox 360, Xbox One, Windows

Set 21 years before the main Halo trilogy, Halo Wars represents the earliest playable period in the Halo timeline. This real-time strategy game follows the UNSC warship Spirit of Fire as it investigates Harvest, a planet of significant importance to the Covenant. Under the guidance of Professor Ellen Anders, the crew discovers Forerunner artifacts that establish key plot elements expanded in later games.

Halo Wars stands apart from the first-person shooter format that defines most of the franchise but provides crucial backstory to the Human-Covenant War. The game demonstrates how humanity initially managed to hold its own against technologically superior alien forces through tactical ingenuity and determination.

Key Moments: The Spirit of Fire’s crew discovers the Covenant’s interest in Forerunner technology, setting up conflicts that would echo throughout the series.

The Fall of Reach and Discovery of the Halo Rings (2552 CE)

Halo: Reach

Developer: Bungie
Release: September 2010
Platforms: Xbox 360, Xbox One, Windows

Taking place immediately before the events of Halo: Combat Evolved, Halo: Reach chronicles the desperate battle for humanity’s military stronghold planet. The game follows Noble Team, a group of Spartan supersoldiers, as they fight against overwhelming Covenant forces in a doomed defense of the planet.

Their mission culminates in securing the escape of the UNSC Pillar of Autumn carrying Master Chief and Cortana – setting up the events of the original Halo game. Reach was Bungie’s final Halo title before 343 Industries took over the franchise, and many consider it the studio’s magnum opus for the series.

Key Moments: Noble Team’s sacrifice to ensure the Pillar of Autumn’s escape, carrying the AI that would ultimately save humanity.

Halo: Combat Evolved

Developer: Bungie
Release: November 2001
Platforms: Xbox, Xbox 360, Xbox One, Windows

The game that launched the franchise begins with the Covenant boarding the Pillar of Autumn after its escape from Reach. Master Chief, awakened from cryosleep by Captain Jacob Keyes, and his AI companion Cortana discover the first Halo ring.

What initially appears to be a weapon to use against the Covenant reveals itself to be something far more sinister – a superweapon designed to eradicate all sentient life to stop the parasitic Flood. The discovery of this ancient Forerunner technology establishes the central conflict that drives the original trilogy.

Key Moments: The revelation of Halo’s true purpose, establishing the stakes for the entire franchise.

Halo: Fireteam Raven

Developer: Play Mechanix, 343 Industries
Release: July 2018
Platforms: Arcade

This arcade rail-shooter takes place concurrently with Halo: Combat Evolved, following a team of Orbital Drop Shock Troopers (ODSTs) aboard the Pillar of Autumn. Beginning on September 19, 2552, with the ship’s arrival at Installation 04, players experience the same events as the original game but from a different perspective, providing additional context to Master Chief’s adventure.

Key Moments: Parallel stories showing how regular human soldiers contributed to the fight alongside Master Chief.

The Battle for Earth and Beyond (2552 CE)

Halo 2

Developer: Bungie
Release: November 2004
Platforms: Xbox, Xbox 360, Xbox One, Windows

Continuing immediately after Combat Evolved, Halo 2 begins with Master Chief defending Earth from a Covenant invasion before pursuing the massive Covenant vessel High Charity through a slipspace portal. The game introduces The Arbiter as a playable character, a disgraced Elite who allies with humanity after learning the truth about the Halo rings.

The narrative raises the stakes dramatically with all Halo installations ready for remote activation, setting up the desperate race to reach The Ark in Halo 3. The dual-protagonist approach enriched the storytelling, giving players insight into both sides of the conflict.

Key Moments: The introduction of the Arbiter and the schism within the Covenant, forever changing the series’ dynamics.

Halo 3: ODST

Developer: Bungie
Release: September 2009
Platforms: Xbox 360, Xbox One, Windows

Set during and immediately after the events of Halo 2, this game follows a squad of Orbital Drop Shock Troopers in New Mombasa after the Covenant capital ship makes a hasty slipspace jump, devastating the city. Players control “the Rookie” as he searches for his scattered squadmates and uncovers a plot involving a Covenant biological supercomputer.

The game’s unique noir atmosphere and focus on regular human soldiers rather than Spartans provides a different perspective on the war, emphasizing the vulnerability of ordinary fighters in this cosmic conflict.

Key Moments: The atmospheric exploration of a ruined city and the humanization of the conflict through the eyes of non-Spartan soldiers.

Halo 3

Developer: Bungie
Release: September 2007
Platforms: Xbox 360, Xbox One, Windows

Picking up where Halo 2 concludes, Halo 3 features Master Chief returning to Earth to defend it once more, this time without Cortana. The game represents the climactic conclusion to the original trilogy, with humanity finally claiming victory against the Covenant.

However, the victory comes at a cost, as Master Chief and Cortana end up stranded in space aboard the damaged Forward Unto Dawn frigate, with Chief entering cryosleep. This bittersweet conclusion left the door open for future installments while providing satisfying closure to the initial narrative arc.

Key Moments: The defeat of the Covenant-Flood alliance and the apparent sacrifice of Master Chief and Cortana to save humanity.

The Reclaimer Saga (2552-2560 CE)

Halo: Spartan Assault

Developer: 343 Industries, Vanguard Games
Release: July 2013
Platforms: Windows, Xbox 360, Xbox One

This twin-stick shooter bridges the gap between Halo 3 and Halo 4. Presented as a training simulation aboard a UNSC ship, it reveals details about a conflict on Draetheus V, a Forerunner facility initially mistaken for a planet. The game features Spartans David and Palmer battling Covenant forces that violated the ceasefire.

While relatively minor in the overall narrative, Spartan Assault provides context for the uneasy peace between humanity and the fractured Covenant forces.

Key Moments: Introduction of Sarah Palmer, who would become a significant character in later installments.

Halo 4

Developer: 343 Industries
Release: November 2012
Platforms: Xbox 360, Xbox One, Windows

After floating in space for nearly five years, Halo 4 begins with Master Chief awakening from cryosleep to find the Forward Unto Dawn under attack by a splinter Covenant faction. Cortana reveals she’s suffering from rampancy, a terminal condition for advanced AIs.

The pair discover the Forerunner world Requiem and face new enemies while uncovering more secrets about the ancient civilization. This game marked 343 Industries’ first full Halo title after taking over from Bungie and introduced a more personal story centered on Master Chief and Cortana’s relationship.

Key Moments: The emotional core of Cortana’s deterioration and the introduction of the Didact as a primary antagonist.

Halo: Spartan Strike

Developer: 343 Industries, Vanguard Games
Release: April 2015
Platforms: Windows, iOS

Taking place across two different time periods, the first part of this twin-stick shooter is set during Halo 2‘s events, while the second part occurs after Halo 4. Like Spartan Assault, the game is presented as a simulation, allowing players to experience historical conflicts from the perspective of a Spartan soldier.

Key Moments: Further exploration of how the UNSC continued operations during the fragile post-war period.

Halo 5: Guardians

Developer: 343 Industries
Release: October 2015
Platforms: Xbox One

Set roughly a year after Halo 4, this game follows two parallel narratives: Master Chief and Blue Team going AWOL to search for Cortana after receiving a cryptic message, and Spartan Locke with Fireteam Osiris tasked with tracking them down.

The game concludes with a resurrected Cortana taking control of AIs across the universe, believing this is the only way to save humanity, while the UNSC attempts to evade her influence. This controversial narrative shift dramatically altered the direction of the series.

Key Moments: Cortana’s shocking heel turn and the establishment of a new galactic threat from an unexpected source.

Halo Wars 2

Developer: 343 Industries, Creative Assembly
Release: February 2017
Platforms: Xbox One, Windows

The crew of the Spirit of Fire awaken from cryosleep near the Ark, a Forerunner installation capable of creating Halo rings. They encounter and battle The Banished, a new Covenant faction led by a Brute named Atriox.

Despite putting up a valiant fight and inflicting significant losses on The Banished, the UNSC crew ultimately find themselves stranded and in need of rescue. This game introduces Atriox, who would later become the main antagonist in Halo Infinite.

Key Moments: Introduction of The Banished as a major new faction and Atriox as a formidable villain.

Halo Infinite

Developer: 343 Industries
Release: December 2021
Platforms: Xbox Series X/S, Xbox One, Windows

Set one year after Halo 5, Halo Infinite follows Master Chief as he continues his mission to neutralize Cortana while exploring the mysteries of Zeta Halo. Simultaneously, he battles against The Banished forces spreading across the ring.

Accompanied by a new AI companion called “The Weapon” and a human pilot, Master Chief faces perhaps his greatest challenge yet in what represents a new chapter in the Halo saga. The semi-open world design marked a significant departure from the series’ linear roots.

Key Moments: The emotional fallout of Cortana’s actions and the fresh start represented by the Weapon AI.
