Easy "Silent Assassin" rank in A New Life mission
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.
Easy "Special Rating" achievement in A New Life mission You will need a minimum of ten headshots for this achievement as well as a silenced sniper rifle, and the foil case. In the A New Life mission, select your sniper rifle as your only weapon. Walk around to the tree house at the end of the street where you find the air rifle. It is at the exclamation point near the ladder in the middle of the map. Unpack your rifle and snipe every FBI agent that gets within your sights. Shortly afterwards, two cars will arrive carrying more agents. Snipe these as well, making sure not to hit any civilians or the dog. You should end up with two guards remaining in the surveillance van out front, one at the front door, and one at the back door. Pack your sniper into the foil case and walk back to the surveillance van, but turn into the open garage on the left. Unpack and assemble the rifle in the back corner, dropping the rifle on the floor of the garage. Walk to the other side of the street and poison the donuts when no one is looking. Wait for the caterer to deliver the donuts and watch the intermission sequence. Enter the van when the jogger is out of sight. Change into an FBI suit and use the phone to call the witness. Leave the van immediately and pick up your rifle. Snipe the guard at the front door and look to the left. You should see the witness on the phone in the living room window; snipe him as well. Enter the house through the door to the left of the garage. Walk north to the bedroom with the open window and climb out. Walk to the back corner of the yard and snipe the final FBI agent at the back door. Pack your sniper rifle up and enter the window again. Leave the case in the bedroom and get your sedative syringe ready. Find the wife of the witness running anxiously through the house and sedate her to take the microfilm necklace. Pickup your sniper case on the way out. Change back into your suit you left in the surveillance van, then proceed to the exit to gain the achievement and read an interesting headline.
