While superficially appearing nothing like a criminal organization, GTA: Vice City describes members of the PIG as a "gang", as evidenced by game's stats, where the PIGs can be declared the player's "least favorite gang" if the player kills more PIG members than those from other gangs. The stats also dubs members of the PIG as the "security guards".
The PIGs mainly operate as a legitimate security force out of DBP Security, but are also involved in some illegal protection services. They patrol the North Point Mall area, Escobar International Airport, Leaf Links Country Club, and Starfish Island.
The PIGs appear many times throughout the story of Grand Theft Auto: Vice City. They provide protection for Congressman Alex Shrub and the band Love Fist, and have links to the Vice City Triads, providing protection for their illegal counterfeiting operation. At one point the PIGs attempt to move in on Tommy Vercetti's protection rackets in Ocean Beach; Tommy wipes out the guards involved, and destroys their office.
Unlike conventional gangs, PIGs do not congregate or move in groups, but rather patrol the streets separately. PIGs are not ordinarily hostile to the player, and will only attack in self-defense; PIG members will also attack the player if they fire a weapon, whether it was aimed at them or not.
In Grand Theft Auto: Vice City, PIGs patrolling Starfish Island may attack or be attacked by the Vercetti Family if they enter the grounds of Tommy's mansion. Likewise, North Point Mall PIGs are frequently in conflict with the Sharks; police act against both parties when gun battles occur. In addition, policemen will pursue and kill PIG members in the same manner as they do with gang members and street criminals, allowing the player to attain "Good Citizen Bonuses" worth $50 each for each attack delivered to a fleeing PIG member. The player must be careful though, as they may attack the player with a pistol.
Grand Theft Auto Vice City
- "Pigs" is a derogatory term for the police.
- In the mission Phnom Penh '86, when the Maverick flies under the Links Bridge, a PIG security guard can be seen jumping off the bridge and into the water. This can be easily spotted if the player pans the camera backwards as soon as the helicopter passes under the bridge. This is an easter egg left in the game by Rockstar.
- If the player attacks and lures a PIG security guard into Fort Baxter Air Base (with the Cop outfit), PIGs will be attacked and killed by soldiers. If a cop is in the area, the police will chase and attack soldiers (soldiers won't fight back).
- In the game's internal files, the PIGs are classified as a gang. Because of this, the security guards exhibit the same behavior as any other gang normally would, such as congregating in small groups, or threatening and attacking the player if he goes in to their "territory".
