In Halo: Campaign Evolved terminals serve as key collectibles that provide extra lore entries for your menu. Unlike Skulls, which appear in sets of three per mission, there is exactly one terminal to find in each of the 13 missions. They are recognizable by their larger size and a small, glowing red light.

Pillar of Autumn

  • Approach Terminal: After leaving the control room overlooking the cryo pods, do not head down the main hallway. Instead, take a 180-degree turn and enter the other doorway. The terminal is at the back of this dark, red-lit room.
  • Forgotten Terminal: After obtaining the first Warthog, continue through the structure until you reach a large room for an enemy encounter. Look for an open window on your right while driving through the tunnel; exit your vehicle, jump onto the ledge, and collect the terminal.

The Truth and Reconciliation

  • Inquisitor Terminal: While searching the brig for Captain Keyes, enter the detention center. Locate the room on the far right that contains cells and a friendly Grunt; the terminal is inside one of the other cells in this room.

The Silent Cartographer

  • Status Update Terminal: In the room where you override the security system, walk to the end of the platform. You will find the terminal behind a small metal structure.

Assault on the Control Room

  • Tangent I Terminal: Locate the tall metal structure in the snowy ravine where enemies spawn. Head inside, follow the ramp up to the outdoor balcony, and find the terminal in the right corner.

343 Guilty Spark

  • Tangent II: After backtracking from the elevator, cross the energy bridge. Before proceeding through the intended door on the left, turn right into a narrow hallway. The terminal is on the left side of this hall, which also contains the first Shotgun in the game.

The Library

  • Tangent III Terminal: When you reach the area with two door controls, interact with the one on the left. Follow the path into the dark room, crouch through the door obscured by Flood material, and find the terminal next to a dead marine.

Two Betrayals

  • Alone Terminal: At the very start of the mission, defeat the four sentinels and turn toward the planetary projection. Run to the opposite side of the circular platform to find the terminal.

Keyes

  • Consumed Terminal: In the Hangar Bay, take a hard left through the door. Follow the narrow hallway past the Covenant enemies and Hunters until you reach the first split path. Take the path on the right to its end; the terminal sits in front of a locked door on the left.

The Maw

  • Arrival Terminal: Right at the start of the mission, head through the mess hall. Clear the enemies, and you will find the terminal on the far right wall, sitting on top of some boxes.

Boarding Action

  • The Path Terminal: After using the Grav Lift with Johnson, head to the upper level. Take the door on the right of the dead-end wall next to the Grav Lift; the terminal is immediately visible on the wall once the door opens.

The Most Dangerous Game

  • Penitent Terminal: In the long room with windows overlooking Covenant drop pods, take a right through the door on the wall instead of proceeding straight. The terminal is inside this small room.

Heavy Burden

  • Harmonious Clarity: In the room with the planetary hologram, enter the ground-floor weapons room. Go through the door in the back to find a smaller room where the terminal sits on a raised platform.
