Halo: Campaign Evolved Missions in Order (All 13 Chapters)

Quick answer

Halo: Campaign Evolved has 13 missions: the 10-mission classic campaign arc plus 3 prequel operations, listed below in play order.

Use this as the chapter list for the campaign: each mission name matches the New Game mission picker, so you can jump straight to the mission you want to replay.

All 13 missions in play order

These mission names follow the New Game mission picker used by Mission Select. The classic arc keeps the Halo: Combat Evolved mission structure, and the three added prequel operations sit at the end of the picker.

  1. 1. The Pillar of Autumn - classic campaign: escape the Pillar of Autumn and reach the ring surface.
  2. 2. Halo - classic campaign: search the open ring valley for surviving marines.
  3. 3. The Truth and Reconciliation - classic campaign: night approach and boarding of the Covenant cruiser.
  4. 4. The Silent Cartographer - classic campaign: island assault to locate the map facility.
  5. 5. Assault on the Control Room - classic campaign: long snowfield advance toward the control room.
  6. 6. 343 Guilty Spark - classic campaign: swamp investigation that changes the mission.
  7. 7. The Library - classic campaign: sustained Forerunner gauntlet toward the Index.
  8. 8. Two Betrayals - classic campaign: return through familiar spaces under new pressure.
  9. 9. Keyes - classic campaign: reboard the Covenant cruiser and push to the captain.
  10. 10. The Maw - classic campaign: sabotage and escape finale aboard the Pillar of Autumn.
  11. 11. Boarding Action - prequel operation set before the classic arc.
  12. 12. The Most Dangerous Game - prequel operation set before the classic arc.
  13. 13. Heavy Burden - prequel operation set before the classic arc.

Where the three prequel operations fit

Halo Waypoint's launch announcement describes Campaign Evolved as including three additional missions set before the events of Halo: Combat Evolved. In the New Game picker they are numbered 11 through 13, after the classic 10-mission arc, so the play order and the story chronology are not the same thing.

  1. Treat missions 1-10 as the classic campaign arc.
  2. Treat missions 11-13 as the added prequel operations.
  3. Check the mode label before following a collectible route, because Campaign Remix uses the same picker.

Chapters, levels, and Mission Select are the same screen

There is no separate chapter-select or level-select menu. The New Game mission picker serves as chapter select: you pick a campaign mode, choose New Game, set difficulty, then choose an unlocked mission and rally point.

  1. Open Campaign, Campaign Remix, or Play Co-op.
  2. Select New Game.
  3. Choose your difficulty.
  4. Pick an unlocked mission and rally point to start or replay it.

What each mission unlock depends on

A mission appears in the picker only once it is unlocked for the profile or lobby in use. In online co-op, the fireteam leader's campaign progress controls which missions and rally points the group can select.

  1. Missing a mission solo? Progress further in the campaign to unlock it.
  2. Missing a mission in co-op? Make the player with the needed unlock the fireteam leader.
