Hitman: Contracts/Hunter and Hunted

Walkthrough
Exit the room quickly and go to the first room on the right when you exit. Go to the window and jump the balcony. Now go forward and check your map. Wait for the enemies to go downwards on the map. Drop down on the trash can not the ground. Go right, ignore the swat officers and look right. Kill the cop. Now from the direction the cop was going, go right from where he was, and kill the cop. Keep going and you will find a sewer to climb down into.

When in the sewers, go to the ladder on the right of the sewers. When you climb out, check your map. From here, look for a blue car, shoot it, wait for the swat to investigate. Now go behind your target and strangle him. Check your map for a exit. When you do that, you are done.
