Detail Orientated Achievement
Use all information terminals in the Shadow Broker’s stronghold
After you've completed the DLC, you'll be in the Shadow Broker's stronghold. After a cutscene, you'll be in a room, able to access several terminals containing information on your squadmates, side missions you can undertake, and even video feeds to certain people and places in the galaxy. There are eight different terminals that you must view for the achievement, and they are as follows.
Dossiers - When you enter the room, on the left
Investment Opportunities - When you enter the room, on the right
Delivery Pickup - Walk across the room, it's in the middle next to the spoiler-free person.
Advanced Training - Turn left from Delivery Pickup
Armor Locker - Take the short stairs up from Advanced Training
Video Archive - From the Armor Locker you'll see a door to your left. Go through that door to another room, it's to the left on a small platform. There's also a music datapad in the room next to another spoiler-free person, but it's not counted as a terminal.
Upgrades - Exit that room and turn left.
Survey Information - Take the short stairs down from the Upgrades and it's on the left next to a round table.
