Hitman: Contracts/Slaying a Dragon

Part 1: Getting to a sniping spot
This mission is the easiest and quickest of perhaps all Hitman games. From your starting position go straight in the direction where the helicopter takes off, and head to the left, towards a three-way intersection. At that three-way intersection, go right and look for a staircase leading to spot overlooking the garden.

Part 2: Equip sniper and shoot
From here, unpack your suitcase away from the street, and move to the view overlooking the middle of the garden. Zoom in to find the red dragon negotiator talking to a blue lotus member. Shoot at the red dragon member, but not the blue lotus member.

Part 3: Escape
Now either drop your sniper and run for one of the exits or put your sniper back into the suitcase and then run for any of the exits.
