Hitman: Blood Money

Follow the instructions and approach the guard at the gate. Knock him out during a cutscene and move through the souvenir shop. Equip you coin and through it through the open window and the target outside to draw the two guards attention away. Quietly move across the courtyard and into the theatre.

Kill the guard torturing the civilian using your fibre wire. Climb the trellis and jump across to the balcony. Equip the shotgun, open the door and blast away at the two guards. Hide their bodies in the crate and the freezer before hiding yourself in the cupboard. A scientist will enter the room. Climb out of the cupboard and kill him with the fibre wire.

Take his uniform and key card and walk slowly along the balcony so not to draw attention to yourself. Walk into the alcove and place your pistol into the crate of baking powder. Pick up the crate and approach the guard with the scanner. He should let you pass providing you haven't got anything metal on you.

Once in the room, drop down onto the roof of the elevator and use your fibre wire to kill the guard below. Drop down and destroy the electricity panel to turn off the lights. Sneak round the drug plant and into the bathroom.

Kill the lone guard and grab the TMP resting on the sink. Charge round the corner and gun down the three guards with your new machine pistol.

Climb the ladder and unpack the sniper case to get a Dragunov Sniper Rifle. Take out the three guards out the window. One is on the Ferris Wheel in the distance. Another on the roof off to your left and the last one is patrolling below. Move out the door and descend the drain pipe.

Make your way over to your left and into the building. Grab the poison and move upstairs being careful to not attract the attention of the guard. Wait for him to move over to the balcony before pushing him over the edge. Move into the office and poison the bottle of cola. Hide in the cupboard and watch as the secretary dies.

Make your way into your targets office and confront him. Kill him in any way you see fit before climbing out the window and grabbing the mine and detonator. Move through the next window and set the mine on the winch controlling the chandelier. Detonate the mine from a safe distance and watch as it kills the drug lord and his friends below. Kill anyone that is still alive and move to the exit.
