After the brief cutscene, move ahead and climb the ladder. Scan the datapad in front of you for 1500 Credits and turn right. Activate the Terminal for the hacker and then open the airlock. Another datapad holds 1500 Credits at the junction.
Turn right, left, then left again to find the generator. Reactivate it and then access the nearby terminal. You can now open the air seal but before you go, run all the way back to where you found the terminal for the hacker.
If you shoot the barrels where the lift is, it will make the lift accessible. Press the controls and then climb down the ladder. Using the lift enables you to acquire the Assault Rifle High-Velocity Barrel I. Now return to the open seal by climbing the boxes.
Head down the ladder and turn left. You will find salvage in the corner worth 1500 Credits. Turn around and go down the stairs and through the door at the bottom. Another door is at the base of more stairs. Stop midway down the next set and take out the Engineer stood by a generator.
Keep the high ground and strafe on the stairs until all the enemies are down. A datapad lies in the room on the left. Scan it for 1500 Credits. The second hacker Terminal is in the right corner of this room. Move to the next door and take cover next to it as more troops are lurking in the next room. An Engineer comes from the right so kill him quickly.
Go into the room the Engineer came from; scan the datapad for 1500 Credits and deactivate the Cerberus lockdown. The doors will open so take cover just inside the doorway. Mechs are in this group so make them a priority.
Move into the next room on the right where you can revive the injured Talon if you want and you will also find the last Terminal for the hacker. Upon exiting the elevator, round the right-hand corner and take cover as another lot of mechs and troopers will try to kill you.
Dispatch them and take cover at the doorway because an Engineer has likely set up a Turret in the vicinity. Kill him and then the Turret. If you move into the room, a shuttle will drop off more troops. Use Flare on the generator near them to stop the mechs from getting shields.
The Engineer likes to set up his Turret on the stairs so kill him once you’ve disposed of the mechs. Finish off the rest and move to the first landing platform. Here you will have the high ground as another shuttle flies in. It’s like shooting fish in a barrel at this point as they make a nice group to exterminate. At the bottom is another cutscene.
Find the Talon leader.
