Halo Campaign Mission Order (All Games)

This article lists every main and bonus mission in the Halo series in the order they appear in each game’s campaign, from Halo: Combat Evolved through Halo Infinite. You get the full mission list for each title, including bonus and hidden levels, plus context on how the campaigns connect and how to access the extra missions.

Halo: Combat Evolved (2001)

The original Halo campaign has 10 missions. There are no hidden or bonus missions in the base game, but the level “The Library” is often considered a bonus-like endurance test because it is a long, linear fight through the Flood-infested facility.

• Pillar of Autumn
• Halo
• The Truth and Reconciliation
• The Silent Cartographer
• Assault on the Control Room
• 343 Guilty Spark
• The Library
• Two Betrayals
• Keyes
• The Maw

The PC port and the 2011 Anniversary remake include a bonus level: the terminal-exclusive “Pillar of Autumn” intro is not a separate mission, but the PC version added a single-player level called “The Silent Cartographer: Evolved” in the 2020 remaster, which is a reimagined version with new encounters and paths. That level is only available in the Halo: Combat Evolved Anniversary multiplayer map pack, not in the main campaign list.

Halo 2 (2004)

Halo 2 has 15 missions, split between the Master Chief and the Arbiter. There are no hidden bonus missions in the original release, but the PC and Anniversary versions include a cut level called “The Heretic” that was repurposed as a multiplayer map. The campaign order is:

• Heretic (Arbiter intro)
• The Armory
• Cairo Station
• Outskirts
• Metropolis
• The Arbiter
• Oracle
• Delta Halo
• Regret
• Sacred Icon
• Quarantine Zone
• Gravemind
• Uprising
• High Charity
• The Great Journey

The original Xbox version had a two-disc design, but the mission list is the same. The “Heretic” level is the Arbiter’s first mission and serves as a tutorial for his new abilities.

Halo 3 (2007)

Halo 3’s campaign has 9 missions, plus a hidden skull that acts as a bonus objective but not a separate level. The order is:

• Sierra 117
• Crow’s Nest
• Tsavo Highway
• The Storm
• Floodgate
• The Ark
• The Covenant
• Cortana
• Halo

There is no bonus mission in Halo 3, but the “Cortana” level is often considered a bonus because it is a self-contained Flood mission that was added late in development. The game also has a terminal system that unlocks extra lore, but those are collectibles, not missions.

Halo 3: ODST (2009)

ODST is a standalone expansion with a non-linear campaign. It has 10 main missions, but the structure is different: you play as the Rookie exploring New Mombasa, and you find audio logs that unlock flashback missions. The mission order depends on the order you find the logs, but the canonical order is:

• Prepare to Drop (intro)
• Mombasa Streets (Rookie)
• Exodus (Buck)
• Kizingo Boulevard (Rookie)
• ONI Alpha Site (Dare)
• NMPD Headquarters (Romeo)
• Kikowani Station (Mickey)
• Uplift Reserve (Dutch)
• Coastal Highway (Rookie)
• Data Hive (bonus mission, unlocked after collecting all 30 audio logs)
• Interior (final mission, unlocked after Data Hive)

The “Data Hive” and “Interior” are the true bonus missions. They are only available after you collect every audio log in the city, and they add a significant chunk of story involving the Superintendent and the Engineer.

Halo: Reach (2010)

Reach has 10 missions, plus a hidden ending that is not a separate level. The order is:

• Winter Contingency
• ONI: Sword Base
• Nightfall
• Tip of the Spear
• Long Night of Solace
• Exodus
• New Alexandria
• The Package
• The Pillar of Autumn
• Lone Wolf

There is no bonus mission in Reach, but the final level “Lone Wolf” is a survival mission that ends when you die, and it has a hidden post-credits scene. The game also has a Firefight mode that is separate from the campaign.

Halo 4 (2012)

Halo 4 has 8 missions, with no hidden bonus levels. The order is:

• Dawn
• Requiem
• Forerunner
• Infinity
• Reclaimer
• Shutdown
• Composer
• Midnight

There is a Spartan Ops mode that is a separate campaign-like series of episodes, but those are not part of the main campaign. The “Forerunner” mission is sometimes mislabeled as a bonus because it introduces the Prometheans, but it is a core story mission.

Halo 5: Guardians (2015)

Halo 5 has 15 missions, and you play as two teams (Blue Team and Fireteam Osiris). The order is:

• Osiris (Team Osiris)
• Blue Team (Team Blue)
• Glassed (Osiris)
• Meridian Station (Blue)
• Unconfirmed (Osiris)
• Evacuation (Blue)
• Reunion (Osiris)
• Swords of Sanghelios (Blue)
• Alliance (Osiris)
• Enemy Lines (Blue)
• Before the Storm (Osiris)
• Battle of Sunaion (Blue)
• Genesis (Osiris)
• The Breaking (Blue)
• Guardians (Osiris)

There are no bonus missions in Halo 5, but the Warzone Firefight mode is a separate co-op mode. The campaign is notable for its split narrative, and the mission order alternates between the two teams.

Halo Wars and Halo Wars 2

Halo Wars (2009) is a real-time strategy game with 15 missions, and Halo Wars 2 (2017) has 12 missions. Neither has bonus missions in the traditional sense, but both have optional objectives within missions. The Halo Wars 2 campaign order is:

• Gatekeepers
• A New Enemy
• Ashes
• One Three Zero
• Descent
• From the Deep
• Fighting Retreat
• Lighting the Way
• Last Stand
• Forge
• High Ground
• Terminus (bonus mission, unlocked after completing the campaign on any difficulty)

The “Terminus” mission in Halo Wars 2 is a genuine bonus level that requires you to finish the campaign first. It is a short, high-difficulty mission that is not part of the main story.

Halo Infinite (2021)

Halo Infinite is an open-world game, so the campaign structure is different. There are 15 main story missions, but you can tackle many of them in any order after the first few. The main missions are:

• Warsaw (tutorial)
• Foundation
• Outpost Tremonius (not a mission, it’s a base)
• Excavation Site
• Recovery
• Nexus
• Spire
• Command Spire
• House of Reckoning
• Repository
• The Tower
• Pelican Down
• Silent Auditorium

Actually, the main missions are: Warsaw, Foundation, Excavation Site, Recovery, Nexus, Spire, Command Spire, House of Reckoning, Repository, The Tower, Pelican Down, and Silent Auditorium. There are also optional side objectives like capturing FOBs and taking out Banished outposts, but those are not story missions. There is no hidden bonus mission in the traditional sense, but the open world lets you replay missions and find audio logs and skulls.

How to Access Bonus Missions

Bonus missions in Halo are rare, and each one has a specific unlock condition:

• Halo 3: ODST – Data Hive and Interior: Collect all 30 audio logs in Mombasa Streets. The logs are scattered across the city, and you need to explore at night as the Rookie. Once you have all 30, the Data Hive mission appears on the map, and after completing it, Interior unlocks.
• Halo Wars 2 – Terminus: Complete the campaign on any difficulty. The mission appears in the mission select menu, and it is a challenging survival-style level.
• Halo: Combat Evolved Anniversary – The Silent Cartographer: Evolved: This is not a campaign mission; it is a multiplayer map variant. It is available in the Anniversary map pack, not in the campaign.

No other Halo game has hidden campaign missions. Some games have skulls that modify gameplay, but those are collectibles, not missions.

Common Misconceptions

One common myth is that Halo 2 has a secret playable level called “The Heretic” that was cut. In reality, “Heretic” is the first mission of the game, but it was originally intended to be a tutorial for the Arbiter. Another misconception is that Halo 3 has a bonus level where you play as the Flood; that is not true. The “Cortana” mission is a regular part of the campaign.

Also, many players think Halo: Reach has a playable epilogue after Lone Wolf, but it does not. The post-credits scene is just a cutscene, not a playable mission.

Frequently Asked Questions

Does Halo 3 have a hidden mission?

No. Halo 3 has 9 missions and no hidden levels. The only extra content is the terminal system that unlocks lore videos, but those are not playable missions.

How do I unlock the ODST bonus missions?

You need to collect all 30 audio logs in the Mombasa Streets hub. Once you have them all, the Data Hive mission appears on the map. Completing Data Hive unlocks the Interior mission, which is the true ending of the ODST story.

Is Halo Wars 2’s Terminus mission worth playing?

Yes, it is a challenging bonus mission that tests your base-building and combat skills. It is not part of the main story, but it offers a unique survival scenario with waves of enemies.

Why does Halo 5 have 15 missions but no bonus?

Halo 5’s campaign is longer than most, but it has no hidden levels. The split narrative between Blue Team and Osiris gives it more missions than other games, but the developers chose not to include any unlockable missions.

Can I play Halo Infinite missions in any order?

After the first two missions, you can explore the open world and tackle many main missions in any order. However, the final mission, Silent Auditorium, only unlocks after you complete the preceding story missions. The game does not have a traditional mission select until you finish the campaign.
