You duck as you nearly lose your head to bullets.

The brief glance did allow you to notice that the turret has been imobilized, it's track on the side. And there seems to be a unshielded ammo feed on the back.

Sammy:
You toss a bolt (rocks being hard to find inside) into the room.

Nothing.
One could assue that it's heat-seeking.
