THIS PAGE IS FOR THE SHIP GENERATED ENTITY, IF YOU ARE LOOKING FOR THE UPGRADE PLEASE TRY THIS PAGE INSTEAD.
General info: Edit
Defense Turrets are automated internal ship defenses with unlimited ammunition and kill enemies extremely rapidly. They have a chance to be generated in every room when you board a derelict save for a few specific conditions (see below).
Larger ships tend to have much more defense turrets than smaller ones.
Defense turrets always start out deactivated when you board a derelict.
Defense Turrets must be activated through an interface terminal by a drone with the Interface Upgrade. After that typing in the command defense' will activate ALL' of them. When powered, the icon for the defense turret will be orange in colour from the ship scheme. Otherwise they appear a faint blue.
Defense Turrets have unlimited ammo and will fire at anything destroying it in a matter of seconds. This is useful when slime is present.
Defense turrets still require power in the room, without which the turret will not fire even if armed. 
Defense turrets don't fire at most deployables.
Defense turrets act similar to opening an airlock in that they will destroy any target when in their respective room save for causing vacuum or radiation. Just remember to disable them once they've done their job.
Conditions for generation. Edit
Defense turrets are never present in a room with an interface terminal.
Defence turrets aren't usually found in very small rooms with several doors.
