Terminal Locations

Terminal locations
The following is a list of all seven Terminal locations. To accomplish the "Marathon Man" achievement, when you find each Terminal, press RB to view the journal. The screen will eventually start to turn red. Wait until it turns blue again and a new entry will appear. You need to view both entries in all Terminals for it to count towards the "Marathon Man" achievement. -From: Jared

The Ark

1. Start the mission, then once you enter the first building, go left into another door. You should now be in a curved corridor. On the inside is a Terminal.

2. After activating the bridge to let your comrades across the gap, turn 180 degrees, and you should see a Terminal (it does not open until you activate the bridge).

3. In the third building after defeating the Scarab, kill the group of sleeping Covenant, then follow the corridor downwards. Once you reach a door in front that is locked, immediately on the left there is an open door. Go through and walk straight off, then turn 180 degrees to find a secret room with a Terminal.
