The mission will begin with Menendez being interrogated, but he will only speak to you (Mason). Go up to the retina scanner and go inside the room with Menendez. As you're talking to him, the ship is attacked and eventually, Menendez will escape.
Access the case on the table for some special knuckles, then go into the room and get some guns. Open the door and go through the hallway, killing the enemies, then go up the stairs at the far end. Salazar will go his way, so go up the stairs and through the door.
You'll now be outside and some enemies will appear in the hallway nearby. Take them out and go through the marked door at the end. As you go through it, there is a turret that will attack you in the small hallway. Destroy it, then go in the side room and hack the Access spot to gain control of another turret in the room ahead. Take out as many enemies as possible before it gets destroyed.
Clear the remaining enemies, then go through one of the side doors and clear the bridge. Use the computer and after that, go downstairs and keep going until you get on a balcony. Don't worry about the soldiers shooting down on the deck and keep going. Go through the next few rooms, shooting the enemies you see, until you get to another one with a turret.
Destroy the turret and hack the Access spot to gain control of another turret. This one might not have as many enemies around, so exit if you can't find any, and continue your hunt on foot. Once it's clear, follow the markers until you come to a room secured by your allies.
After a few scenes, you'll be in control of Menendez, right outside the server room with Briggs. After some more scenes, you'll have a choice to either shoot Briggs in the leg to wound him, or to kill him by shooting him in the head. You'll gain control of Mason again after another scene, so go through the air ducts and into the server room.
Once everything is over with, follow Harper until you arrive in the hangar bay. Some more scenes will play out, then you need to go to the marker, where you'll be raised to the deck. Kill any enemies you see and start making your way to the VTOL to escape. Once you board it, the mission will be over.
