Halo Campaign Evolved Mission List and Order

Halo: Campaign Evolved officially confirms 13 campaign missions. Ten of them rebuild the original Halo: Combat Evolved campaign in order, and the remaining three form Operation: METEORITE, a separate bonus prequel arc. The mission total and the two verified METEORITE names are settled, while overall completion time and the bonus arc's exact Mission Select placement remain To be confirmed.

How many missions are there?

Halo Waypoint states that the campaign has 13 missions in total. Ten are rebuilt versions of the original Halo: Combat Evolved missions, and three are new missions that belong to Operation: METEORITE. The bonus arc is a separate campaign set one year before the original story, not a continuation of the classic sequence. Because the official research does not confirm where METEORITE sits in Mission Select, this guide keeps the arc separate rather than numbering it as missions 11 through 13.

The count is confirmed by two official sources that agree with each other. Halo Waypoint's overview names the total, and the Halo Support Collectibles article verifies the ten classic mission names, the two new mission names, and one Terminal plus three hidden Skulls per mission. That cross-check is why this guide treats 13 as settled even though several smaller details stay open. Readers can rely on the number while treating the gaps listed below as genuinely unresolved.

The ten classic missions in order

The ten classic missions follow the same order as the original Halo: Combat Evolved campaign, beginning with Pillar of Autumn and ending with The Maw. Each one is rebuilt with high-definition visuals and refined gameplay while preserving the original level flow and story beats. The table above lists every classic mission in order alongside its verified Terminal name and collectible count, so use it as the authoritative sequence. One mission, Two Betrayals, carries a known progression issue: destroying the Banshee after the first generator can block progress, so leave that vehicle intact.

The classic arc follows the Master Chief and Cortana from the Pillar of Autumn's crash onto the ring, through the discovery of the Flood, to the destruction of Halo in The Maw. Rebuilding these ten missions let Halo Studios add the broader weapon and vehicle sandbox without changing the original level order. The numbered sequence in the table matches the order players unlock missions in Mission Select for the classic campaign. Treat that order as the verified path for a standard playthrough of the rebuilt story.

Operation: METEORITE

Operation: METEORITE is a three-mission bonus campaign set one year before the events of Halo: Combat Evolved. Its official premise follows the Master Chief and Sergeant Avery Johnson as they infiltrate a Covenant agricultural ship holding orbit over the glassed human colony of Promise. Across the arc they battle Sacristan warriors, liberate UNSC marines, and face experiments run under the mysterious San'Shyuum Minister of Harmony, while searching for data that could lead to the Covenant's fabled homeworld of High Charity. Two of the three mission names, Boarding Action and The Most Dangerous Game, are verified in the official Collectibles article.

The arc introduces enemies and a setting that are not present in the original campaign, which is why it sits as a separate group rather than a continuation. The official overview frames Operation: METEORITE as the place where players see new mission content for the first time. Because its missions use a separate arc order rather than the classic numbered order, the table above lists them under their own arc-order column. The two verified names stay stable across the official article, while the third does not.

The final mission-name conflict

The third Operation: METEORITE mission does not have a single settled name. The same Halo Support article calls it Bitter Harvest in its Terminal table and Heavy Burden in its achievement section, which is why the conflict note in the table above preserves both terms without promoting either one. Even though the name is unresolved, the mission's Terminal (Harmonious Clarity) and its collectible count of one Terminal plus three hidden Skulls are still official. Treat the two names as a documented source disagreement rather than a typo to correct, and treat the conflict as unresolved until Halo Support reconciles the wording.

Terminals and hidden Skulls by mission

Halo Support states that every one of the 13 missions contains exactly one Terminal and three hidden Skulls. That rule gives 13 Terminals across the campaign and matches the repeated official total of 39 hidden Skulls, with the per-mission counts shown in the table above. The same official Collectibles article also visibly lists 42 Skull names, which creates an unresolved mismatch with the stated total of 39. Because of that mismatch, this page does not publish a reconciled Skull database, individual Skull-to-mission assignments, or exact Skull locations.

Terminals and hidden Skulls are the two collectible types tracked per mission, and both feed into the broader collection and Campaign Remix systems. The official Collectibles article confirms the per-mission counts but does not publish exact Skull locations, so this guide does not publish them either. Players who want a complete Skull-by-Skull list should treat any third-party location guide as unverified against the official record. The same caution applies to mapping individual Skull effects to specific missions.

How long the campaign takes

The saved official research does not include an authoritative main-story or completionist length for the campaign. Without a verified figure, this guide leaves campaign completion time as To be confirmed rather than repeating a community estimate. Player-reported times vary widely and are not part of the official record, so they are not presented here as a reliable measure. Anyone planning a run should treat any specific hour count as unverified until an official source publishes one.

The bonus Operation: METEORITE arc adds its own playtime on top of the classic ten missions, but no separate length figure is published for it either. Because neither a main-story total nor a completionist total is verified, this guide offers no number at all. Readers who are planning their time should wait for an official figure or track their own sessions instead.

Known gaps

The verified record stops at the mission total, the classic order, the per-mission collectible rule, and the two METEORITE names. Beyond those settled facts, the details below are unresolved and labeled To be confirmed rather than filled in from inference. None of them should be guessed from the confirmed 13-mission count.

• Operation: METEORITE's exact placement in Mission Select.
• An authoritative final name for the third METEORITE mission.
• Main-story and completionist playtime estimates.
• Exact Skull-to-mission assignments and Skull locations.
• Mission-specific achievement details.
