Remember Me Walkthrough Part 32 – Episode 6: Rotten Core (Maintenance to Prisoner Lockers)
Head on forward down the maintenance tunnel you appear in deep back in La Bastille. Go forward, climbing up the ledge then keep going forward. After that Edge starts talking to Nilin giving her the next set of instructions. Bad Request is still locked up in here apparently.
As you turn to the right, look to the left and move to that wall. Move along it slowly and you will get an odd Sensen prompt. This is just past the first turn inside the depths of La Bastille. Head all the way down to the left and search for the Scaramech that you can find in that area.
With the Scaramech added to your collection head back to the main hallway and continue forward to the elevator. Use the Force Spammer to move the 2 grates off the elevator door then raise the shutter from the bottom of the elevator. After all that you can opening the elevator itself. Just head toward it and a cutscene will run where the elevator arrives.
As it makes it way up you will find Nilin has to engage a number of Strangler Leapers. As the Episode has just started Nilin has no focus and Stranglers cannot be seen unless they are in bright light or hit with Sensen DOS. The best thing to do for now is simply keep on the move and watch for the incoming attack prompt. Use that to dodge around and avoid the attacks. When the elevator arrives its doors will open and you will finally have a source of light. At that point move in close to the elevator and stay there, if not inside the elevator. Beat up the Stranglers then hit the button to head on down.
When the elevator stops you will be on the thirteenth floor underground. Just outside the elevator is a SAT Hatch if Nilin needs to get healed up after that last fight. Take a moment to find the nearby Errorist Memory Panel, over to the right, to learn where Nilin's and Bad Request's lockers are. It will be important soon enough. Go over to the right from the Errorist Memory Panel and look straight across the way. There you will find the movement controls for the middle rack. Use the Force Spammer to lower it down as far as it will go. After that go to the left of the Errorist Memory Panel and head on down the stairs. Head over to the rack you lowered and climb onto it. Get to the top and vault over to the other side. From there Nilin can leap over to the ledge above. Head on through the force field to activate the control post.
Now Nilin needs to sift through the other lockers to find Bad Request's locker. Just slide enough of them in turn over to the left until they are pulled away. When you get to the Fourth Locker you swill find Bad Request's. Open it up to get the Pick-Socket.
Now it is time for a quick tutorial on the Pick-Socket. Grab the energy from the window panel and and move it to the door controls so you can open them. After that put the energy back into the window panel. It important to note that the Hunt Glove and still use the Spammer and Junk Bolt while carrying a Pick-Socket charge. In fact, from this point on, try to constantly have a Pick-Socket charge in the Hunt Glove as there are numerous locations that need that very charge. This just means grab it after you get through the door you are presently using it for as much as possible.
There is still one more thing to go for in the lockers. Start sliding the lockers once again until you get to Nilin's. Open it up to get a Focus Boost that is otherwise very well hidden.
