HALO: CAMPAIGN
EVOLVED
The original Halo campaign, rebuilt as a modern journey through the ringworld—then extended with a new beginning.

The premise
A ringworld, an invasion,
and a weapon too large to use.
After the Pillar of Autumn reaches an artificial ringworld, the Master Chief and Cortana fight to preserve humanity's survivors while uncovering the Halo installation's real purpose.
Campaign Evolved keeps that narrative spine, but refreshes its presentation and introduces new playable material before the original story begins.
Operation: Meteor
Three new prequel missions place the Master Chief alongside Sgt. Johnson before the familiar campaign begins.
A new read of CE
Updated cinematics, sound, environments and mission flow frame the same central mystery for a new generation.
Campaign field guide
Read the campaign as
three connected layers.
This page gives the high-level route. The next sections turn that route into a useful reading order without pretending an editorial overview is a full walkthrough.
A campaign built around escalation.
The classic route remains the reference point: arrival, discovery, reversal and escape. This guide keeps that progression readable before it turns into a mission-by-mission resource.
New material should earn its place.
The added prequel material is framed here as an opening context, not a replacement for the original campaign. Read it alongside the mission index when you want the full route.
What changed matters more than a checklist.
Use the companion pages to separate a confirmed feature, a design interpretation and a changing player reaction before treating any of them as a final verdict.
