Halo: Campaign Evolved All Achievements and Trophies Guide

Halo: Campaign Evolved offers players 58 achievements and trophies. On Xbox and Steam, they add up to 1000 Gamerscore, while the PlayStation list includes a Platinum trophy. Some rewards unlock automatically as you progress through the story, but a significant portion is tied to finding Skulls and Terminals, replaying the campaign on different difficulty levels, and completing highly specific challenges on certain missions. In this guide, we will go over every achievement and trophy in Halo: Campaign Evolved, explain how to unlock them, and highlight the hardest challenges that deserve special attention.

Each of the campaign's 13 missions, including the ten original missions and three new Operation: METEORITE missions, grants a separate achievement for completion regardless of difficulty:

A separate achievement line is awarded for completing the entire campaign on each of the four difficulty levels. However, the Heroic and Legendary achievements may be blocked by certain difficulty modifiers, so before starting a run, it is better to check which Skulls are enabled:

This is the largest category in the game. One achievement is awarded for collecting every Skull and Terminal in each of the 13 missions, with several additional achievements tied to total collectible progress:

A separate small achievement line is tied to completing missions in the randomized Campaign Remix mode. It unlocks after collecting any three Skulls. Along with it, the Adaptation, Armistice, and Reload Skulls are automatically unlocked:

This category is not tied to specific missions and counts progress cumulatively across the whole playthrough, so you can complete it gradually on any level:

Some achievements require you to activate specific Skulls before completing certain parts of the campaign, making them some of the most niche challenges on the list:

These are the hardest achievements in the game, requiring precise completion of specific conditions during certain mission segments:

Fully Evolved: the PlayStation Platinum trophy, awarded for earning all other 57 achievements and trophies in the game.

To unlock every achievement in Halo: Campaign Evolved, it is important to plan your completion route in advance. Some rewards will unlock naturally through the story, but Skulls, Terminals, Campaign Remix, LASO, and individual mission challenges are better handled in separate runs so you do not waste time on unnecessary restarts.

There are 58 achievements and trophies in total. On Xbox and Steam, the list is worth 1000 Gamerscore, while the PlayStation version includes a Platinum trophy.

You will need at least several full playthroughs: a regular run for mission and collectible achievements, a separate Legendary run, a deathless Campaign Remix run, and a LASO run.

MYTHIC and Mix Master are the two most demanding goals on the list. MYTHIC is awarded for completing the entire campaign with LASO enabled, while Mix Master requires completing the entire Remix campaign without dying once. Both require strong route knowledge, careful play, and dedicated preparation.

Yes. The Fully Evolved Platinum trophy requires you to earn all other 57 achievements and trophies, including the full collection of Skulls and Terminals.

Not always. In the official list, each achievement has a separate note indicating whether difficulty modifiers prevent it from unlocking. Before attempting Heroic, Legendary, LASO, or a deathless Campaign Remix run, it is better to check which Skulls and modifiers are enabled.

Campaign Remix unlocks after you collect any three Skulls. After that, the game automatically adds the Adaptation, Armistice, and Reload Skulls to your collection, and the mode becomes available from the main menu.

In total, you need to collect 39 Skulls and activate 13 Terminals. Full completion is required for the Headhunter, Lore Have Mercy, and Collector's Addition achievements.
