Frighteners is a mission in Grand Theft Auto: Liberty City Stories given to protagonist Toni Cipriani by Leone Family Don Salvatore Leone from his home in the Saint Mark's district of Portland, Liberty City.
Toni drops by Salvatore's place once again, and this time, Salvatore tells him to scare some of the union bosses into allowing him to use the docks. Toni gets into a vehicle and chases down one of the union big shots. Toni smashes into the car and eventually forces him to exit his car. Toni gets out of his vehicle and beats up the union boss.
Toni chases the second union boss and again forces him out of his car, beating him up while avoiding the union boss' pistol. Toni then chases the third union boss and scares him out of the car. After all three union bosses have changed their minds, the mission is over.
- The player can kill one of the union bosses, but killing more than one will cause the player to fail the mission, since the goal is to frighten them; not kill them.
