Part 122

Place the Device on the other side of the wall. When the wandering Guard comes by, subdue him, hide him, and open the door.

Step outside, turn right, shoot the Camera on the window, then find and shoot the Camera on the Observatory. Run through the window to get inside.

Go to the stairway, look up, and shoot the Camera above the door.

Go back up the stairs, place the Device halfway up. When the exterior Guard is at the door, activate the Device, open the door, toss the Pipe inside, and hide in the Study.

As the Guard investigates, throw a Brick to stun him. Pick up the Device and Pipe, and drag him to the Bedroom for hiding.

When Silvio is not in the Observatory, subdue the Guard who enters and exits, and dump him in the nearby Container.

Return to the door and stand in the open doorway. When Silvio returns, he will go to his computer.

The goal is to kill Silvio by dropping the large Mobile onto him. On Master Difficulty, you need to lure him to the center of the room.

Under the Observatory dome, shoot the electrical box. Go back inside to the Lab. Aim at the chain and wait for Silvio to reach the center as he investigates the box. Shoot the chain to drop the mobile and kill him.

Go outside, climb the Pipe to the roof, and stay at the top. Shoot the Camera on the corner of the Villa. Approach the Villa.

Pick open the door to the Bathroom and enter Silvio's Bedroom. Go into the Storeroom, shoot the large model ship, and get the Virus Prototype.

Sneak to the Small Office. When she goes to the desk and the Guard goes to the corner, open the door, toss the Prototype at her to kill her, and close the door.

Go back outside, keeping an eye on the Guard above, and return to the Pipe. Go back down, inside, and outside. Run to the Kitchen door and wait for a Kitchen Assistant to be in the corner closest to the door and another in the opposite corner. Sneak inside behind the Chef and to the Pantry.

Go out through the window to your Safe House. Go into the kitchen and grab the Explosive Golf Ball. Go onto the Patio and use the Pipe to go down.

Go through the Terrace Shops area, then down to the Beach Restrooms area. Go to the Blocked Tunnel and toss the Golf Ball at it when the Bodyguard is away. This will blow a hole in the wall to the Biolab area.

Wait for things to calm down, then go through the hole into the Biolab. Grab the Wrench at the corner.

Sneak up to the stairs to the Break/Security Room and shoot the Recorder through the window with your Silverballer to disable Cameras. Run to the Container under the stairs and hide until things calm down.

Go southwest towards the two large groups of pallets and hide behind the south group.

Around the Seaplane area, sneak up on the patrolling Guard when his back is to you. Throw stun him and hide him in the nearby Container.

Go to the Seaplane, then north to the Ledge, and east towards the Raised Area.

Climb up, over, and down the other side of the Raised Area. Find the Metal Boxes and hide behind them. Shoot down the Stalactite.

Go back over the Raised Area, turn left to find a Container. Get inside and wait for things to completely calm down.

Exit the Container, go to the Ledge, and to the Seaplane to leave the mission.
