How to play the Halo games in order: chronologically and by release date

If you're looking to play the Halo games in order, I've brought together this handy guide to break it all down for you.

Here, you can find all of the major Halo games and some off-shoots compiled below in two different orders. Starting with the release date order first, you can find a list that gives you an overview of the series as it originally launched, from its beginnings in 2001, right up to the latest new game in 2026 with the arrival of the remake, Halo: Campaign Evolved (which you can find out more about in our Halo: Campaign Evolved review).

For those of you looking to explore the series in narrative order, I've also detailed how to play the Halo games chronologically, with overviews of where each entry sits in the Halo timeline and if or how the events of the games connect story wise. Of course, alternatively, you can also explore the series by checking out our ranking of the best Halo games if you're after the highlights, too. But for an overview of how to play the Halo games in order, read on.

How to play the Halo games in release order

How to play the Halo games in chronological order

If you're instead looking to play the Halo games in chronological order, the list looks quite different. While, for example, Halo: Combat Evolved was technically the very first Halo game to release, later Halo games take you to earlier points in the Halo timeline of events. So, if you're looking to experience the narrative of the series chronologically, I'll break it down for you here.

With both a list so you can see the order at a glance, as well as a more detailed overview of the timeframes and how it ties into the overall narrative, you'll also find current platforms listed where you can still play these today.

• Halo Wars
• Halo: Campaign Evolved (prologue missions)
• Halo: Reach
• Halo: Combat Evolved
• Halo 2
• Halo 3: ODST
• Halo 3
• Halo: Spartan Assault
• Halo 4
• Halo Spartan: Strike
• Halo 5: Guardians
• Halo Wars 2
• Halo Infinite

1. Halo Wars (2531)

Halo Wars is the first real-time strategy game set in the Halo universe, and it's also technically the first game in the series narratively speaking. With the events of Halo Wars taking place some 21 years before Halo: Combat Evolved (and, of course, its remake, Halo: Campaign Evolved).

Taking place in the year 2531 during the tail-end of the Harvest campaign – which revolved around trying to reclaim the colonist world of Harvest that's been ravaged by the alien Covenant empire (who are determined to destroy humanity). You play as one of various leaders and take command of either UNSC military units who are part of the Red Team, or the Covenant, and get thrown into the conflict. The parasitic threat known as The Flood also factors into the campaign.

2. Halo: Campaign Evolved (2551 - Prologue missions)

For the most part, Halo: Campaign Evolved serves as a shiny new remake of Halo: Combat Evolved, but there are some new bonus prequel missions introduced that place it earlier in the timeline narratively.

Taking place a year before the main story of Campaign Evolved (and Combat Evolved) and prior to Halo: Reach, these Operation Meteorite missions explore a self-contained story featuring Master Chief and Sergeant Johnson teaming up to infiltrate and investigate a Covenant research vessel above the colony of Promise. It mostly establishes that Chief and Johnson were best pals before the events of Halo 1, but also introduces a new Prophet character, who may be more important in the inevitable Halo 2 remake.

So, if you do want to play the Halo games in order, it could be worth tucking into Campaign Evolved over Combat Evolved, or play it before you play the original if you're keen to try both. However, you won't be missing much by skipping these prequel missions and going straight to the next game.

3. Halo: Reach (2552)

Halo: Reach brings forward the Halo timeline from Wars, but is still a precursor to Halo: Combat Evolved. And rather than being an RTS like Wars, it's an FPS like the majority of the series.

Taking place a few weeks before the events of Combat Evolved in the year 2552, the game explores the Fall of Reach, a key human colony planet that served as one of the last bastions of military strength against the Covenant.

The campaign sees you playing as super solider Spartan B312 (aka Noble Six), a member of the elite Noble Team, who are sent to look into a distress beacon on the planet. It soon becomes apparent that the Covenant are on Reach and you'll get swept up in countless battles against the alien invaders as they continue their devastation from the Harvest campaign. Reach's ending then almost immediately leads into the start of Halo: Combat Evolved.

4. Halo: Combat Evolved (2552)

The FPS that kicked off the Halo Series, Combat Evolved (and its 2026 remake, Halo: Campaign Evolved), bring the events forward from Halo: Reach some weeks later. Still set within the same year of 2552, Combat Evolved follows Spartan John-117, better known as Master Chief, who begins the game in cryo sleep aboard the UNSC ship Pillar of Autumn after the Fall of Reach.

The Pillar of Autumn is quickly overrun by the pursuing Covenant, and Captain Jacob Keyes charges Master Chief with protecting the ship's AI Cortana from falling into the hands of alien forces. But after you crash onto an ancient, mysterious ringworld (aka a Halo) known as Installation 04, you'll soon find yourself fighting back against the Covenant forces that revere it and uncovering its true purpose.

5. Halo 2 (2552)

Also taking place in the year 2552, Halo 2 unfolds following the events of Combat Evolved. But rather than solely focusing on Master Chief, Halo 2 also explores a Sangheili warrior called Thel 'Vadam who holds the title of The Arbiter.

Playing as both characters at different points in the narrative (before their plotlines eventually converge), the game sees the Human-Covenant war escalate, with the aliens now invading Earth. Master Chief starts the fight aboard Cairo Station before eventually battling through the city of New Mombasa, which sets up what's to come in Halo 3: ODST. Meanwhile, the Arbiter contends with The Flood on another Halo known as Installation 05.

6. Halo 3: ODST (2552)

Halo 3: ODST actually takes place during Halo 2 and acts as a prequel of sorts to Halo 3. Taking on the role of an Orbital Drop Shock Trooper called Rookie, you set out to find out the motivations behind the Covenant's attack and invasion of the city of New Mombasa on Earth.

Shaking up the combat, ODST introduces some stealth as you try to survive against the overwhelming enemy forces. Structurally, it's also quite different to other games, featuring some open world exploration as you explore the ruined streets of New Mombasa at night looking for clues as to where your missing squad mates are, which lead into more linear missions that show the chaos of the Covenant's invasion. Overall, it builds up a more complete picture of the Battle for Earth prior to the events of Halo 3.

7. Halo 3 (2552)

Halo 3 then sees out the year 2552 with the return of Master Chief, who's back in the leading role. The Arbiter also makes another appearance, although now he's only playable in co-op multiplayer. Set a few weeks after the events of Halo 2, the third entry follows on from ODST to bring the original Halo trilogy to a close.

After crash landing into an African jungle, Master Chief sets out to finally finish the long fight against the Covenant. As you battle against enemy forces, you also work to uncover a secret that could turn the tide of the fight. But along the way, you'll also have to contend with the threat of The Flood, too. With Halo 3 officially wrapping up the Human-Covenant War, the game ends with Master Chief entering cryo sleep on the UNSC Forward Unto Dawn ship – which is left adrift in space – to await rescue.

8. Halo: Spartan Assault (2554)

Set between the events of Halo 3 and Halo 4 in the year 2554, Halo: Spartan Assault is an off-shoot entry in the series that plays as a twin-stick, top-down arcade-y shooter rather than the mainstay FPS format of the core trilogy. Originally released on PC and mobile before coming to Xbox 360 and Xbox One, it features over 30 campaign missions.

Its concept revolves around a training simulation tool for Spartans. As you try to progress your career as a prospective Spartan, you'll be drawn into key battles that take place within the timeline. As the games go, this is one of those off-shoot you don't really need to play to follow the overarching narrative of the main series.

9. Halo 4 (2557)

Picking up where Halo 3 left off, Halo 4 takes place less than a handful of years later, and follows Master Chief as he's awakened by Cortana on the Forward Unto Dawn ship – which is still adrift. Cortana, now several years old, is starting to suffer from rampancy, making her unstable.

The duo eventually find themselves on the Forerunner world known as Requiem, where soon enough, he finds himself facing the Covenant and another threat in the Forerunners (another advanced alien species) with the mighty Didact as their commander.

10. Halo Spartan: Strike (2557)

Just like Halo Spartan: Assault, Halo Spartan: Strike is another off-shoot twin-stick shooter set in the Halo universe. Narratively speaking, it does jump a little in terms of the timeline, with it including events that took place in 2552, but it's technically set in the year 2557. As another smaller experience that doesn't hold as much weight as the mainline games, this is another one you could miss without much trouble.

But if you want to experience it, this is where it sits within the timeline of events, and it kind of mirrors the concept of Assault in that it's another series of missions centered around a tactical simulation training tool that was originally developed for mobile.

11. Halo 5: Guardians (2558)

Halo 5: Guardians takes place in the year 2558 after the events of Halo 4, and puts you in the role of both Spartan Jameson Locke, who's a part of ONI (Office of Naval Intelligence), and Master Chief. When series hero Master Chief goes AWOL after going after Cortana with his Blue Team Spartan allies, you as Locke set out to bring him back with Fireteam Osiris.

Playing as both characters at different points throughout the campaign, our original Halo 5: Guardians review picked at its story, which doesn't feel as cohesive or impactful as its predecessor, with much of its events feeling more inconsequential in the grand scheme of things.

12. Halo Wars 2 (2559)

Just like the first Halo Wars game, Halo Wars 2 takes the series back to the realms of strategy and sees the Spartan Red Team awaken from cryo sleep 28 years after the events of the first Wars game. Set in the year 2559, it takes place in the timeline following the events of Halo 5 and sees you play as a leader of your choice as you command your own army and take on a new threat in the Banished, a Brute-led faction born out of the Covenant.

With the option to play as either humanity, or the Banished in the story, you build up bases, take charge of troops and vehicles, and navigate battles in missions centered around the Ark – a Forerunner installation first seen in Halo 3

13. Halo Infinite (2560)

As the most recent game to release in the Halo series (outside of the Campaign Evolved Remake), Halo Infinite is also the latest entry in the timeline, with events unfolding in the year 2560. Taking place roughly 18 months after the events of Halo 5: Guardians, Infinite sees you assume the role of Master Chief as the war against the alien Banished faction has effectively been lost.

With Halo Infinite being set on a Halo ring known as Installation 07 (Zeta Halo) which is coming back online and poses another threat, Master Chief works to shut down the Halo. Cortana's actions from Halo 5 are largely glossed over and, while she features in the story, Master Chief instead finds himself paired with a new AI known as The Weapon.
