In Halo: Campaign Evolved, one of the new types of collectibles added to this remake of the first Halo is the Terminals. These are computer-like devices or control panels that unlock lore entries in the main menu when found, allowing you to read classified information, details about events in the Halo universe and other interesting tidbits.
There are 13 Terminals in total, with one in each mission of the campaign. They're usually hidden, so in this section of our guide, we'll show you exactly where to find them so you can collect them easily. Bear in mind that once you've collected a Terminal, it will count as obtained and you won't need to finish the mission. Finding them all also unlocks several trophies/achievements, including "Lore Have Mercy" and "Collector's Addition" (if you also find all the Skulls).
During mission 1 of the bonus campaign, titled Boarding Action, you can find and collect The Path Terminal.
Immediately after following Johnson to an upper level of the ship using an elevator, turn around when you reach the top and look for a side door like the one shown in the following image:
As soon as you open this side door, you'll see the Terminal mounted on the wall directly ahead. Make sure you open it before continuing with the mission.
During mission 2 of the bonus campaign, titled The Most Dangerous Game, you can find and collect the Penitent Report Terminal.
While searching for the captured UNSC survivors, shortly after opening the second set of cells, you'll need to walk through a corridor leading into a room with windows on your left, a door at the far end that leads onward and another side door on the right.
As shown in the image above, go through the door on the right to enter a small room where you'll find the Terminal in plain sight.
During mission 3 of the bonus campaign, titled Heavy Burden, you can find and collect the Harmonious Clarity Terminal.
As soon as this Rally Point begins on the ship's bridge, head toward one of the doors on this floor, like the one shown in the following image:
Go through the door, pass through another one into a room containing weapons and then continue through one more door leading to a small room. The Terminal is located here, behind a weapon rack.
During mission 1 of the main campaign, titled Pillar of Autumn, you can find and collect the Approach Terminal.
Shortly after making your way through some dark maintenance shafts with the help of your flashlight, you'll reach the control room above the cryogenic chamber where you began the mission. In other words, you'll arrive in the room shown below:
As soon as you open the next door leading into a corridor, don't continue down it yet. Turn around to the left to see a small room with an open door. The Terminal is located at the back, as shown below:
During mission 2 of the main campaign, titled Halo, you can find and collect the Forgotten Terminal.
After holding out against a lengthy enemy assault, you'll need to drive a Warthog and will soon enter a huge cave. Shortly after heading inside, you'll see what looks like a large window on your right, as shown in the following image:
Stop here and get out of the Warthog. You now need to drop over the edge of the window onto the walkway directly below to find the Terminal.
During mission 3 of the main campaign, titled Truth and Reconciliation, you can find and collect the Inquisitor Terminal.
After reaching the ship's bridge, your next objective will be to rescue Captain Keyes from the brig. Follow the main path until you enter a room containing three locked green doors. Go through the first door on the right, which is the one shown in the following image:
This door leads through a short corridor into a room containing several cells. Once inside, interact with the panel that unlocks the cells and enter the only one containing a dead Marine. You'll find the Terminal beside his body.
During mission 4 of the main campaign, titled The Silent Cartographer, you can find and collect the Status Update Terminal.
Once you enter the building containing the holo-panel that disables the substation's security system, head into the corridor directly behind the holo-panel, as indicated by the arrow in the following image:
Follow the corridor toward the marked position and you'll find the Terminal behind one of the structures at the far end.
During mission 5 of the main campaign, titled Assault on the Control Room, you can find and collect the Tangent I Terminal.
While driving the Scorpion tank toward the Ziggurat control center, you'll travel through an uphill ice tunnel before emerging into a large open area containing a huge rock in the middle and two paths on either side.
Take the path on the left and look for a green door, as shown in the image above. Go through the door to enter a building inside the rock, eliminate the enemies and head up the slope to the balcony above. You'll find the Terminal at the far-right end of this balcony:
During mission 6 of the main campaign, titled 343 Guilty Spark, you can find and collect the Tangent II Terminal.
At one point during the section where you need to escape from the Flood, you'll pass through a room containing a light bridge and a large whitish window on the wall. It's the room shown in the following image:
The mission objective directs you through a door beneath the window. On the other side, you'll enter a corridor with dead soldiers and shotguns lying on the floor. Instead of continuing through the door at the far end, go around the corner, as indicated in the screenshot, to find the Terminal in the corridor behind the wall.
During mission 7 of the main campaign, titled The Library, you can find and collect the Tangent III Terminal.
After taking the first elevator down to the lower chambers and waiting for the Monitor to unlock a large door blocking your path, you'll enter another room where you're supposed to interact with a panel on the right to continue the mission. Instead, activate the panel on the left to open a door on this side.
Go through this side door and shoot the infected growth blocking an opening in the wall. Climb through the opening into a room behind the wall, where you'll find the Terminal among several bodies.
During mission 8 of the main campaign, titled Two Betrayals, you can find and collect the Alone Terminal.
As soon as the mission begins, in the first room where you regain control after the cutscene, turn around from your starting position and circle around the platform toward the back to find the Terminal.
During mission 9 of the main campaign, titled Keyes, you can find and collect the Consumed Terminal.
While heading toward the ship's bridge, you'll eventually reach a shuttle bay like the one shown in the following image:
As soon as you enter, turn left and you'll see a door at the far end. Go through it to enter a corridor, where you'll soon encounter a large number of enemies. Eliminate them and head down the corridor. As soon as you can, turn right and then left to find the Terminal.
During mission 10 of the main campaign, titled The Maw, you can find and collect the Arrival Terminal.
During the first part of the mission, while making your way toward the ship's bridge, you'll encounter several enemies in a corridor. Eliminate them and look for the door to room BO3L, as shown in the image below:
Enter this room, which contains several cafeteria-style tables, and look along one side for the Terminal before continuing with the objective.
