After recieving a phone call shortly after the mission Riot, requesting his services, Tommy Vercetti pays Colonel Cortez a visit on his yacht. Cortez talks about a man named Gonzalez, who has been a trusty companion to him for years. It appears that Gonzalez owes Cortez a few things, and he now has a great level of incompetency. Cortez claims that the ambushed drug deal was caused by his loose tongue and orders Tommy to kill Gonzalez. He gives him a chainsaw and then tells Tommy that he will be rewarded.
Tommy heads to Gonzalez' location in Vice Point, where he finds that Gonzalez is being protected by two members of Diaz' men. Once in the penthouse, Gonzalez spots Tommy with his chainsaw, and begins to flee from the penthouse. Tommy quickly runs after him and kills him while alarming the police of the killing. Tommy, now wanted by cops, drives a vehicle to the nearest Pay 'n' Spray and loses the cops, sucessfully completing his mission.
The reward for completing Treacherous Swine is $250. The mission Mall Shootout for Cortez is now unlocked. Also, the Casual Outfit is now available at the Gash store in the North Point Mall. The player can also keep the chainsaw obtained in the mission.
