Armored buses, also known as terror buses, were enemy vehicles that appeared in Infamous. They were originally just ordinary transportation buses before the Dust Men captured them and equipped heavy layers of scrap metal armor coatings and machine guns on all sides.
Following the arrest of their leader Alden Tate, the Dust Men began using these vehicles to shoot down pedestrians of the Warren left and right. During the mission "Terrorized Streets," Cole MacGrath needed to disable each bus before the situation could escalate. Several more needed to be destroyed during the "Terror Bus" series of side missions.
