The air is cold around you as you sit on the roof of a tall building, your sniper moves as you try to get a clear shot of your victim. A quick assassination, "easy". You finally get a clear shot and put your finger on the trigger, talking it off when you hear 4 clicks of guns from behind you. "Get up and turn around, hands up." I low voice is heard from behind you, it's raspy, the voice of a smoker.
