Kyle Reese: Listen! And understand. That Terminator is out there! It can't be bargained with, can't be reasoned with! It doesn't feel pity or remorse or fear, and it absolutely will not stop. EVER! Until you are dead!
When the Terminator breaks into the police station, he has an auto-shotgun in his left hand, and a machine gun in his right. Before he kills the power in the building, he comes to the end of a hall, points his shotgun through a doorway, and shoots. A machine gun sound is used for the blast, instead of a shotgun sound.
