Two-Faced Tanner

Two-Faced Tanner is a mission in Grand Theft Auto III, given to protagonist Claude by Yakuza co-leader Asuka Kasen from her condominium in the Newport district of Staunton Island, Liberty City.

Mission
Claude drops by Asuka's place, only to find out that she and Maria have gone shopping. Claude reads a note left by Asuka, which states that the Yakuza's police informant has said to them that one of their drivers is an undercover cop. She then tasks Claude to kill him.

He then heads to Kenji's Casino in Torrington. Once there, the driver is seen hopping onto his car. Claude then follows the car and tries to damage it enough to make him pull out of his car, all while having a four-star wanted level. Once he has bailed, Claude quickly kills him.

Mission objectives
In order to complete the mission the player must:
 * Head over to the Casino
 * Take out Tanner

Script
(Claude, reading a note.)

Asuka Kasen: Maria and I have gone shopping. Our source in the police has informed us that one of our drivers is a strangely animated undercover cop! He's more or less useless out of his car, so we've tagged it with a tracer. Make him bleed!

Reward
The reward for this mission is $20,000.

Trivia

 * The driver, along with his name, is a reference (and a mockery) of Tanner, the protagonist of the Driver video game series. He is mentioned by Asuka as being "useless outside of his car" which makes fun of the fact that being on-foot in Driver 2 gives you no options but to just walk around. To make fun of the series even more, the cop is given a female running animation, making fun of the strange way Tanner ran in Driver 2. He is also dressed in a similar way to Tanner as well. This mission started the rivalry between GTA and the Driver series.
 * It is optional to do this mission, the player can complete other missions, however after the player has completed Grand Theft Aero, this mission would be disabled.
