Finding all 13 hidden data points in Halo Campaign Evolved requires thorough searching, as none of the terminal locations match the ones found in Halo Combat Evolved Anniversary. Unlike skulls, these terminals do not make noticeable ambient noise—they only emit quiet bleeps and bloops when you are standing directly next to them. Each of the 13 missions features a single terminal that unlocks specific lore entries.

Quick Overview: All 13 Terminal Locations

  1. Pillar of Autumn: Upper cryo room or the Forerunner tunnel.
  2. Truth and Reconciliation: Inside a prison room near the brig.
  3. The Silent Cartographer: Behind a Forerunner structure near the security console.
  4. Assault on the Control Room: Inside a central rock formation room off the canyon.
  5. 343 Guilty Spark: Down a dark corridor past the dead marines.
  6. The Library: Through a hole in a Flood-infested wall near the start consoles.
  7. Two Betrayals: Along the ring walkway after clearing Sentinels.
  8. Keyes: Near an inclined corridor junction in the shuttle bay.
  9. The Maw: In a nook on top of UNSC boxes inside the mess hall.
  10. Boarding Action: Behind you after taking the gravity lift upwards.
  11. The Most Dangerous Game: In a storage room off the hallway with sarcophagus-like devices.
  12. Heavy Burden: Hidden behind Covenant equipment in a storage room past the armory.

1. Pillar of Autumn Terminals

The Pillar of Autumn mission features two terminals depending on your rally point:

  • Approach Entry: From Rally Point Charlie, go through the upper cryo room with cracked windows where Cortana mentions the Covenant catching you napping. Proceed through the next door, turn left immediately into a small room with red lights and screens, and find the terminal at the far end.
  • Forgotten Entry: From Rally Point Bravo, drive your Warthog into the Forerunner tunnel until you reach the straight section with two bumps and a large window on the right. Jump through the window and drop to the ledge directly below.

2. Truth and Reconciliation Terminal

Inquisitor Entry: From Rally Point Charlie, make your way toward the brig to find Captain Keyes after clearing the command room. After navigating corridors, enter the large room with perimeter doors, go through the first door on the right into a prison room, deactivate forcefields via the central console, and check the cell almost opposite the console.

3. The Silent Cartographer Terminal

Status Update Entry: From Rally Point Bravo, immediately after shutting down the security system, turn around and head to the outer walkway. Look for the extended platform behind a small Forerunner structure equipped with two pointy bits.

4. Assault on the Control Room Terminal

Tangent 1 Entry: From Rally Point Charlie, emerge from the ice cave into the canyon, follow the path right, and enter the doorway in the central rock formation on your left. Follow the corridor to a large empty central room, go up the ramp to the balcony, and check the right corner.

5. 343 Guilty Spark Terminal

Tangent 2 Entry: From Rally Point Bravo, back track through the Flood-infested Forerunner facility until you pass through a door flanked by two large pale symbols. Turn left past the dead marines, then take the next right down a dark corridor.

6. The Library Terminal

Tangent Trilogy Conclusion: From Rally Point Bravo, after 343 Guilty Spark opens a large door with two consoles, ignore the objective prompt on the right and activate the console on the left. Go through the newly opened doorway, squeeze through the small hole in the Flood-infested wall, and check the small room containing a dead marine.

7. Two Betrayals Terminal

Alone Entry: From Rally Point Alpha, right after destroying all attacking Sentinels, ignore the door straight ahead. Instead, head right and run around the ring walkway.

8. Keyes Terminal

Keyes Lore Entry: From Rally Point Charlie, drop to the ground floor of the shuttle bay, follow the objective marker through the door, and head right up the inclined corridor containing Flood and two Hunters. At the first junction halfway up, turn left then left again.

9. The Maw Terminal

Arrival Entry: From Rally Point Alpha, after clearing out the mess hall room, bear right from the entrance to locate the terminal in a nook sitting on top of UNSC boxes.

10. Boarding Action Terminal

Heavy Burden Entry: From Rally Point Delta, take the gravity lift upward toward the Triumph of Tolerance upper decks. Once the lift drops you off facing the final combat corridor, turn completely around and go through the door on the right.

11. The Most Dangerous Game Terminal

Penitent Report Entry: From Rally Point Charlie, fight through the ship after rescuing the marines from the brig until you reach a room with windows displaying sarcophagus-like devices on the left. Instead of proceeding through the next door, enter the room on the right to find a UNSC gear storage room.

12. Heavy Burden Terminal

Final Terminal Entry: From Rally Point Bravo, start at the ground-floor room facing a pair of distant doors. Go through those doors and another set to enter a Covenant armory, then pass through the next door into a small storage room. The terminal is tucked behind Covenant equipment on the left.
