Halo 3: the 7 Terminals

The Ark

1. Begin the mission and when you enter the first building take a left into another door and now you should be in a curved corridor, on the inside is the Terminal.

2. After you have activated the bridge to let your comrades across the gap, turn around 180 degrees and you should see the Terminal (it doesn’t open until you activate the bridge).

3. In the 3rd building after you have defeated the scarab, kill the group of sleeping Covenant then follow the corridor downwards.  When 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 around 180 degrees to find a secret room, the Terminal is in there.

The Covenant

1. When in the 1st tower standing on the lift, face the access panel and turn left.  Jump over and the Terminal is there.

2. Land your hornet on the 2nd tower, walk towards the entrance and when you see the locked door turn around 180 degrees, the Terminal should be right there in front of you.

3. When you are in the 3rd tower standing on the lift, face the access panel and turn right.  Jump over and the Terminal is right there.

Halo

1. When you reach the end of the 1st cave, hug the wall on the right and you’ll see a building.  Jump up onto the walkway and go left when you get inside, the Terminal is right there.
