Gun turrets are very basic and cheap defensive structures and the easiest way of automatic defense. They use magazines as ammunition which can be refilled manually or by [[inserters]] and mean that enemies cannot have resistances to their attacks. They do not require power and can operate practically anywhere as long as they have sufficient ammunition. Fully upgraded and provided [[piercing rounds magazine]] they can potentially deal more damage than laser turrets ([http://www.factorioforums.com/forum/viewtopic.php?f=16&t=4363&start=20 see thread]) but suffer a reduced range. The gun turret damage upgrade stacks multiplicatively with the bullet damage upgrade. Fully upgraded this means 2.2*2.2=4.84 times as much damage; 9.68 damage with regular bullets or 24.2 damage with piercing bullets. A piercing bullet kills small enemies in one shot, and deals more damage to a heavy biter/spitter than a laser shot does.

Turrets are defensive structures that can be crafted after being researched. They come in two different tiers with different health, shooting speed, range, ammunition, damage type and damage per shot.


Gun Turrets

Gun turrets are very basic and cheap defensive structures and the simplest element of automatic defenses. They use magazines for ammunition which can be refilled manually or by inserters. They do not require power and can operate practically anywhere as long as they have sufficient ammunition. Gun turrets deal double damage per shot as compared to the man-portable pistol and submachine gun, but have somewhat lower fire rate than the latter, so absent any turret-specific upgrades it does 1.33 times as much damage per second as the submachine guns. The gun turret receives bonuses from technologies that improve bullets so it keeps pace with the submachine gun as those improve, and they also receive bonuses from their own damage upgrade. These two damage effects stack multiplicatively: fully upgraded, bullets do 2.2 times as much damage as a standard bullet, and turrets do 2.2 times as much damage as a standard turret, so bullets from a turret do 2.2×2.2=4.84 times as much damage as without the upgrades, totaling 19.36 damage from regular and 48.4 damage from piercing bullets, more than fully-upgraded laser turrets can provide, though still not quite enough to kill medium spitters in a single shot.

Laser Turrets

Laser turrets are an advanced defense building with a longer range, good damage and use electricity to operate (and when idle). Dealing laser damage they don't face any resistances (enemies receive full damage) but have a lower rate of fire than gun turrets. Each shot costs a constant 800kJ of energy; as the shooting speed increases through upgrades, so too does the power required to keep firing.
