Hitman: Codename 47/Kowloon Triads in Gang War

Run towards the end of the street heading from behind your car. Pass the locked double gates and run a few hundred yards down the road (in the same heading), until you see an alley on your right. Go through it and run straight past the park, then at your first chance turn left. Run down the road, then turn right up an alley. Then enter the left and press the button for elevator. It take you to the roof, so unpack the sniper rifle on the way up. When at the top, run to the opposite end of the roof. Stay close to the side that faces the road. A cut scene will then come on showing the Blue Lotus member disembarking from the car. Then another cut scene will start, and the Red Dragon member gets out of his car. Aim at the Blue Lotus member and wait. When the Red Dragon member gets to him, they bow. Shoot the Red Dragon member, making sure it's a head shot. Load the sniper rifle and get out of scope mode. Another cut scene will appear showing a helicopter. Wait for it to finish, then aim at the gunner quickly and fire, and wherever you hit him he should fall. Then leave the roof after packing up the R93 and head back to your car.
