Part 2

Once at the building, press 'Y' to drop your legs, then press 'B' to drop down. Press 'B' again before landing for a silent landing. Aim to make every landing silent.

Crouch and move past the lighted window. At the corner, shoot out the lamp on the elevated hook.

Turn the corner and approach the closed door. The 'Door Options' window will appear. Select 'Optic Cable' by holding 'A' and moving the left thumbstick up.

In the optic cable view, rotate the right thumbstick to scan the room.

Once you confirm the room is empty, press 'A' to return to third-person view and open the door.

Move into the darkest room to the right. Shoot out the light near the window before proceeding.

Use the Optic Cable on the next door, then pick the lock.

Proceed into the room to the right, crouching in the shadows. Climb the pipe, but first shoot the lantern next to it. Wait a few seconds to see if there is any response to the shot.

After confirming no noise, climb the pipe and crouch at the top. Move left to the far corner with a trap door.

Scan the area below with the Optic Cable, then open the trap door and drop down. Ignore the lantern on the floor.

Crouch to the doorway. Shoot out the lantern on the porch outside that illuminates the stairs.

Proceed down the steps, turn right, and move along the fence to the left until you reach a square-shaped opening beneath a porch. Enter in a crouch.

Proceed down the tunnel until it ends in a small yard. Shoot out the light hanging over the steps to the boarded-up door.

Proceed around the darkened corner; the game will automatically save.

Keep going forward. At the top of the next steps, pick up the ammo. Go down the steps to the left.

At the bottom of the steps, turn right. Stand Sam up, move him to face the board fence on the left, then click down on the left thumbstick to flatten him against the wall ('Wall Mode').

Move him through the narrow corridor. At the end of the fence, hold the left thumbstick to the right to peek around the corner.

You will see a guard sitting on a box facing away. While peeking, press 'A' to perform the 'SWAT Maneuver' to quickly move to the other side of the doorway.

Peek around the corner again by holding the left thumbstick to the left. Tap 'X' to draw Sam's pistol.

Aim for the lantern on the wall and shoot it out. The guard will investigate.

Sneak up behind the guard. When close enough, the 'Grab Character' window appears. Tap 'A' to grab the guard in a headlock.
