Terminals 1-3
Terminals 1-3 are all found on the level, “The Ark”. The first terminal is found the first time you walk inside (in a small hallway). The second is located right next to the control panel that lets the Scorpion tanks across the bridge. The third is located under a set of stairs after the room with the sleeping Grunts.
Terminal 1
The first time you go inside, you will see a door almost immediately on the left. Simply enter this area of the level to find the first of the seven terminals.
Terminal 2
When you go inside the structure to let the tanks across the bridge of light, there will be a Terminal almost directly behind the controls for the bridge. It’s an easy find!
Terminal 3
You’ll miss this terminal if you are not careful. After defeating the scarab, you will head into a large structure. There will be a room with several sleeping grunts. Nearly directly following this room is another room in which you can take two different directions. There is a door, and a staircase (both eventually lead to the next room).
Underneath the staircase is an additional door that leads to the 3rd terminal.
