There are thirteen terminals for each level of the game. Players can access them by finding and interacting with them. Finding the terminals can be a bit tricky with the more open environments.
Cairo Station Terminal
The first terminal can be found when players enter the station. The player needs to destroy the second Orbital Defense System to gain access to the hallway that leads to the armory.
Players must kill the elites in the hallway before proceeding to the armory. Once up the stairs, two more elites will spawn. The terminal can be found on the right-side wall.
Outskirts Terminal
This terminal is located in the final open area of the mission. Players will battle multiple waves of enemies on the beach. There is a single bunker before the final tunnel. It is on the lower level on the right wall.
Metropolis Terminal
The terminal is inside the building that the Marines have taken refuge in before the scarab fight. After destroying the three wraiths outside the building the terminal can be found behind a few crates in the hallway.
The Arbiter Terminal
Players will first need to fight through a number of enemies and make their way through the hanger area. Following the objective, they will need to head down a series of descending hallways until they reach a larger room.
This terminal is located in the large room with two blue conveyor belts transporting fusion cores. It can be found against the back wall of the raised platform right before the exit.
Oracle Terminal
During the start of this mission players will need to take a long elevator ride while fighting off multiple waves of enemies.
After the elevator ride, players will have to break the glass which leads into a room filled with Flood and Heretics. The terminal is located behind a wall on the left side.
Delta Halo Terminal
After the first small battle players will need to extend a draw bridge that is guarded by two Wraiths.
This terminal is located in the building that players have to enter to release the draw bridge. It can be found in the same room with the button to release the bridge on the left.
Regret Terminal
This terminal is found about halfway through the mission after a long series of battles and elevator rides. After the elevator ride, players will find themselves in a three-story room
Players can find this terminal in a room filled with several kinds of enemies. It can be found on the top level on the left side next to the hologram.
Sacred Icon Terminal
Once players hit the mission’s third objective they will descend down multiple fusion cores. Eventually, they will come through a hole with a divider that splits it.
After dropping to an area where they can see a skybox in the distance, the terminal can be found behind the support column to the right.
Quarantine Zone Terminal
This terminal can be found during the first portion of the mission simply by following the objective. After fighting through waves of Flood the players will have to enter a burning building.
After entering the burning building the terminal can be found on the ground level. Following the wall to the exit will bring the player to the terminal.
Gravemind Terminal
After making it halfway through the mission players will enter a wide-open area with Brutes and Elites fighting.
When players enter the outside area with a large skybox, instead of following the exit players should inspect the small alcove to the left. The terminal will be behind a few purple pods.
Uprising Terminal
Players will need to fight through a series of Brutes and Wraiths before making it down the river.
After heading down the waterfall and river there will be a bridge with a wraith underneath. There will be several pillars, and the terminal can be found behind them.
High Charity Terminal
During the third objective players will take the elevator. After killing all the enemies, players will enter a room with a sword on an alter. To the left of the entrance, the terminal can be found.
The Great Journey Terminal
This final terminal can be found in a room filled with jail cells. The top middle cell on the upper level contains the terminal. Shooting the shield generator will release the cell and lead to the terminal.
