Start the mission with no weapons except for your standard equipment. First, go to the back of the food truck when the delivery man is walking off. Pick up the donuts, then take them around the corner so that nobody can see you. Put them on the floor and then scroll through your inventory. Select the Sedative Syringe, then look down at the donut box and inject the sedative into them. Pick up the donuts again, put the syringe away, then go back to the food truck. Drop the box of donuts on the floor directly behind it, then walk away. The delivery man will pick up the donuts and take them to the FBI van across the road. Wait a short time and an short intermission sequence inside the truck will appear, showing the FBI agents falling asleep. Go to the back of the truck, open the door when prompted, and go inside. When inside the FBI truck, suit up as an FBI agent, and steal the video tape, which should be on the left side of the van as you go in. Do not pick up any weapons. Leave the vehicle and go up to the front of the house and walk inside. Go out the back towards the shed, which is in the top right hand corner. Wait until there is nobody around. If the pool man goes in, do not try to follow him or your suspicion bar will go into the yellow. When there is nobody around, pick the lock, go inside, and pick up the lighter fluid. Exit the shed, go right, and then go towards the pool. Over to your right is a barbecue. Go up to it and you will get the Rig the Barbeque option. Select it, then go inside the house and wait under the stairs. Stand around for a short time and a short intermission sequence will show a woman being burned alive. When she is dead, go back outside and pick up the microfilm that she is wearing around her neck. Go back inside, then go up the stairs. Turn right across the landing, then go straight. Open the first door on your right, then go in and wait behind the L-shaped wall. If the main target is already there, wait for him to leave, then wait awhile for him to return. When he returns, make sure he has his back towards you, then fibrewire him. When he dies, drag his body to the place you were hiding (the L-shaped wall). Then, sprint out of the house towards your escape as quickly as possible. If done in a short time, you should get either a Hitman rating or Silent Assassin rank. Either way, you will get $100,000 and if you have already completed the game you can purchase an additional upgrade to your custom weapons whenever you select a mission.
