Collectibles in Halo: Campaign Evolved

This article covers the Terminals and Skulls available to collect in Halo: Campaign Evolved, including related unlockables and achievements.

How to Find Collectibles

Several collectibles can be found throughout each story mission. All collectibles can be collected or interacted with by using the Interact action. The default input is the X button on the XBOX controller, Square button on the PlayStation®controller, and the E key on keyboard.

When searching for collectibles, environmental clues are often present in the surrounding area. For example, an unusual cave or side path may lead away from your current objective and toward a collectible. All collectibles emit an audible sound when you are nearby, which can help you pinpoint their exact location.

Collectibles grant platform‑specific achievements, such as Gamerscore on XBOX or Trophies on PlayStation®. Skulls can also unlock additional modes and enable unique gameplay modifiers.

Terminals

Terminals contain written lore entries that expand the story of the Halo universe. Each mission includes 1 UNSC Terminal to discover, for a total of 13.
