One Shot, One Kill

This mission is given by Hsin Jaoming in Grand Theft Auto: Chinatown Wars. It involves the assasination of an FIB informant who is the key witness against Chan Jaoming.

Walkthrough
Upon receiving the mission, you drive to Castle Garden City and enter a hotel. On the hotel balcony, you assemble a sniper rifle from a briefcase. You then have to shoot the informant (distinguishable as he is wearing a white t-shirt and jeans). He drops a special blue dollar sign upon death, which is worth more than the green dollar signs pedestrians drop. The mission is completed when you lose the resulting three star wanted level.

Mission completion unlocks By Myriads of Swords.

Script
(At Hsin's Residence)

Hsin: They let Chan out on bail.

Huang: Great. How is he?

Hsin: Hidden. Hidden away where he can cause me no more trouble. Now, tell me - are you loyal, Huang?

Huang: I'm a Triad. You can trust me.

Hsin: Your uncle is bitter and power crazed and your father was a buffoon. It was one of Chan's trusted entourage that sold him out.

Huang: How do you know ?

Hsin: I have some cops on my payroll. They tell me he's the Fed's star witness against Chan. The only thing I want him witnessing is a bullet entering his brain.

Huang: I'll get right on it.

Hsin: Don't get caught Huang I can't have this coming back to me. Take him out from a distance.

Huang: For a second I thought you were concerned for my welfare.

Hsin: Mess this up and you'll be the one worrying about your welfare.

Mission Replay description

Apparantly, one of his own entourage sold him to the FIB, and is their chief witness against him.

Hsin got me to impress upon the informer how much we disapproved of his treachery."

Trivia

 * The name One Shot, One Kill maybe came from the US Sniper School motto of the same name. Also, in Call of Duty 4: Modern Warfare, a flashback mission of the protagonist's squad leader, Captain Price has also the name One Shot, One Kill and also had the same objective: to kill someone important; but in the GTA version, it is an informant of FIB, while in Call of Duty, it is to kill a weapons dealer whom sell weapons to mercenaries so that the dealer could get the mercenaries to his Ultranationalist party. Both of the missions requires the player to shot at a distance and to escape. The differences are that in the GTA version, it utilizes a simple sniper rifle, as in Call of Duty, an M82A1 SASR, an incredibly powerful weapon that can be shot from far away and can easily rip off a body part is used; in the GTA version of the mission, the target is killed upon being shot while in Call of Duty, the target survives with the arm ripped off by the bullet.( In Call of Duty 4, doesn't matter where you shot the target, even in the head, the target always have his right arm ripped off.) In the Call of Duty version of the mission, it is a 2 man black op mission while in the GTA version it is a normal assassination mission.
