Act 4: C2 - Answers

Then follow Dom to a second terminal. When you move up, take cover and wait as the patrol passes by. Then head toward the terminal, but before using it go left and find a journal by the wall, then use the computer.

Move up and basically you just follow Dom and take cover when he does, and if he runs up to a spot you can too because no matter how close you are to the patrol, they won't spot you. Use the terminals until you get the right one, which I believe is three terminals up.

Take cover after the scene and get ready for a wave of a few wretches and a bloodmount from the right side. Again, pick to either aim for the beasts or the big target first, not both at once. Then another wave to the left which should reach you quicker and perhaps a few wretches from the first wave. Then to the right will be a grinder and drones, dood to snipe and toss frags. The last wave to the left will be Theron Guards and drones with shotguns, so snipe the guards from behind cover, the one near the terminal, and it shouldn't be too hard if you aim is good. Then it's scene time.
