"My Police source indicates that the FBI has mounted a surveillance operation at key locations around the city. It is too late to contact anyone and avoid incrimination, so you must take out these spying cops, but be careful...they're bound to have back up."
Claude drops by Asuka Kasen's condo, and she introduces him to her brother Kenji. Asuka informs Claude that the FBI establishes a surveillance operation. The player is required to track down and eliminate three groups of surveillance crews waiting at different spots within 6 minutes and 30 seconds, but may deal with them at any order. They include:
The Rumpo used by the FBI in this mission has a unique jet black color. It cannot be seen as normal car on the streets, and matches other vehicles used by the FBI in both GTA III and Grand Theft Auto: Liberty City Stories. It can be obtained by killing the two gunmen inside and can be kept without failing the mission. A video of this can be seen here.
If Claude drives or walks below the building in Torrington, he can hear gunfire, but will not be hit, due to the angle to hit Claude. They can only hit him when he shoots snipers at them from Kenji's Casino. A video of this can be seen here.
In the PS2version of the game, Asuka talks about Mafia and the subtitles match with what she says. In the PC version Asuka talks about the FBI and the subtitles don't match. A video of this can be seen here.
After completing this mission, map icons for Pay 'n' Spray garages and Ammu-Nation shops no longer appear on the radar, so it is advised that players make a mental note of their locations for future use.
