Victoria's Ward
With the girl in your arms, turn left and walk out of the door. From here, it's a pretty linear walk through the halls of Rosewood. You'll walk through offices and nurseries. Soon you'll come to an elevator with a red light over it. Off to the left will be some curtains. If you go through the curtains and stand still, you'll be hidden. Do this because in a moment, a group of men will come off of the elevator and walk through this hallway. Wait for them to pass and when they are gone, walk onto the elevator behind them.
Orphanage Halls
When the elevator stops, climb up through the open hatch in the roof and then jump up to the open elevator door but don't pull yourself up. There will be two men up above. Wait for them to walk away. Pull yourself up and follow them. Turn right at the second door and you'll enter a room with a laundry basket. In the next room will be some guys beating up a guard and another man to the right, watching.
Hug the right wall and slip behind the thug who is watching. In the next hallway, turn right and you'll enter a lab room. At the end of the row in the middle will be the Syringe which is part of the Needle Pusher and Subtle Injection challenges. Grab the fuse on the desk in this room and then go into the next room (The fuse will be in the same room but different location on Professional difficulties). Head back into the lab room now and wait for the thugs that are beating up the guard to leave and go downstairs. If the man in the next room looking over the railing doesn't follow kill/subdue him and stick him in the closet.
Follow the thugs don't the stairs but keep a safe distance. When they've gone, get to the bottom and hit the checkpoint. Turn the corner and walk up the hall but before you turn right in the large room, search by the baseboards on the right hand wall for a vent. This vent will run under the stairs and lead to a small area just off the main room.
When you exit, you want to make your way quickly across this area because the large group of thugs will disperse and one of them will come over to here. Take cover against the counter to the left and slide right. Swap to the next cover and then follow that counter right into the next room. In this small room will be a closet by the door, a first aid kit in the corner and then another fuse on the desk (This will move to the play room on Professional). Pick up the fuse and then exit this room.
As you come out of the room, you'll see the large group of thugs to the left and they may be about to break up. Turn right and walk away from them. You'll go past a play room on your left but avoid that because it is heavily guarded. Go around the play room the long way. Follow the hall and take two lefts to do so.
On the far side of the play room, you'll see a large room with a bunch of small drawers. If you were fast, you may have beat the thugs here and you might be able to grab the fuse at the back without any trouble. If not, most of them don't go to the right side of the fuse. Take up position by the door and wait. Eventually, they will all turn away from the door that you are at and you can run over and grab the fuse (Same room but harder to get on Professional). Wait for another opening before you exit.
Now, just retrace your steps back past the play room but when you get to the point where you need to cross the long room to get to the vent, avoid it. Stay on the inside wall of the hallway. Approach the corner closest to the central lounge room. There are a lot of people in there patrolling but that's ok. There are only three that you really need to worry about.
The first will come almost up to the corner where you are hiding but stop short. Wait until he leaves before transferring to the short walls to the left. There's another similar patrol that will come just far enough up but not around the corner that he can see you. He will come up between the two short sections of wall. The last guy is more dangerous. He's in the long room that you snuck through before. He will patrol it long ways. Wait for him to move in the direction of the vent and then cross the short wall, being sure to avoid the man in the middle of the room. If you can cross the break in the short wall, you can move quickly to the far left side and you should be safe.
Get back up the stairs and cut through the lab again. Watch to make sure there's nobody looking in the room with the guard. Slide through back the way you came and head back to the elevator. There will be one door on your left (that you passed before).
Go through this door and down the stairs. At the bottom of the stairs will be a small room and the last fuse will be in this room (This fuse will be in the room on the left on Professional difficulties and requires a disguise). Grab the fuse from the shelf and then go through the door closest to the closet. You'll enter a room with a few guys talking and there will be a piece of Evidence on the front of the reception desk here but it will require a disguise. Directly across from where you are will be another door. Go through that door and then through the small maintenance room to find the elevator control room. Against the wall on the right will be the fuse box. Put the fuses in and then pull the lever next to it.
Central Heating
When you enter central heating, you'll see a couple of guys up ahead talking. Take cover behind the bed just to your left. There's a gun on it that you can grab if you like. Move to the left and around the corner. Roll to the left again and stop at the column. After they finish talking, round the corner and then roll to the next column. From there, walk through the door just to your left.
You'll find yourself in a hallway, make your way to the end and turn right in the next room. Move down to the end and you'll see that this hall curves to the right. Take cover behind the pile of sheet rock. Further along the hallway by where the two guards are chatting is another pile of sheet rock which has Evidence on it. When you get the chance, continue to move around the sheet rock so that you end up moving forward and then back to the right into the little side hallway.
In this hallway, climb up to the catwalk above. Move forward until you are past the brick wall on the left. You'll see a sheet of metal that blocks the gap in the railing. Take cover behind this and then move to the right by rolling from sheet to sheet. Move across the small bridge and to the next section of catwalk over the pipes. Again, move from metal sheet to metal sheet going to the left.
Stop when you are at the top of the stairs and when the guard at the bottom moves to walk away, move around the stairs to the left. At the end of the catwalk, drop down and then walk to the door on your left by walking behind the guard.
Follow the hallway and go through the door. You'll come out on a small platform above some stairs and Wade will shoot at you. This room is pretty linear. Just walk through it towards the cluster of arrows that indicate Wade and his men. When you get far enough, Wade's men will appear and time will slow down. Your goal is to shoot Wade as he leaps from cover to the right without shooting the other men. Just be patient, they will miss. When he jumps out, shoot him once to kill him and end the mission.
