This is the last part of the Shaving Lenny Mission in which you subdue Lenny and eliminate the rest of his gang, namely Mason and Luke, with signature kills. This guide explains how to complete this mission on the hardest, purist, difficulty. It does not explain how to complete the different challenges in this area.
At the end of this guide is a YouTube video with a visual version of this guide.
When you start immediately crouch walk forwards (just behind the enemy walking past) until you get to some stairs to the left. Go down the stairs and go to the right at the bottom of the stairs. Take cover on the bench and go to the edge and pick up the bottle. Go back until you are behind the barrel with the pizza box on it and throw the bottle just to the right of the right police officer:
And then you barely have enough time to go across towards the wall to the right to get out of sight. Pull the lever in front of you. Then turn around and approach the opposite wall. You will be able to jump on a ledge and pull yourself up. Go around the corner and, as soon as you can, jump to the next ledge and pull yourself up. Follow the ledge until you can climb into the window. Go through the room and into the next straight ahead. Go into that room and wait for the door to close behind you. Then open the door and throw a wrench towards the cabinet on the other side of the other room:
Take cover on the right side of the door and wait for the police officer to walk into the room and check on the noise. Once he has his back turned on you crouch walk up to him and subdue him. You can hide his body in the cabinet ahead. Then go back into the other room and look across the platform to check whether the other police officer is leaning on the railings. If he doesn’t, wait for him to do so but be sure to stay out of his line of sight:
Once he is standing correctly go towards the door and on your way there pick up the hammer from the table. Make your way across the platform behind the police officer and down the stairs. Ahead you will see a disguise, put it on. Then turn around and throw the hammer close to the police officer sitting on the couch:
Around this time your screen will flash as though you have been noticed. Don’t worry, you haven’t. What has happened is that your actions from earlier when you unscrewed the wire and pulled the lever has come into effect, you have eliminated Mason with a signature kill. As soon as the police officer has gotten up crouch walk up to him from behind and take him out. Drag his body out of the room through the door behind you and hide him in the cabinet. Then stand up and walk out of the corridor and towards the kitchen:
Go through the kitchen and into the side room. Stand in the far corner to the left of the door when you face it. Shortly after you stand there Luke, your other target, walks into the room. Wait until you can hear the door closing, then equip your fiber wire and garrote him:
Hide his body in the crate to the left. Then make your way back to where you took out the police officer who was sitting on the couch. Lenny will be sitting in one of the barber chairs. Walk up to him and Pacify Lenny. Once you have it is the end of this part of the mission, and in fact the end of the Shaving Lenny mission.
