Mini-turret

Mini-turret

"A portable automatic turret. Requires steel to refurbish its barrel after heavy use. May explode when damaged. Its dumb AI brain can't be directly controlled, so beware of friendly fire."

The mini-turret is a stationary defense mechanism which automatically fires at any enemies entering its range of 24.9 tiles. It fires a 3-round burst with no need for warmup, has a slow 4.8 second cooldown and 96% per-tile accuracy. While turrets are somewhat underwhelming on their own, large groups of turrets are able to incapacitate or kill small groups of hostiles within seconds.

After firing 120 rounds it requires a barrel change, costing:

• 20 steel in Peaceful and Base Builder difficulty
• 30 steel in Medium difficulty
• 40 steel in Rough difficulty and above

Turrets have a 50% chance of exploding when it reaches 20% health.

Construction

Constructing the turret requires research in gun turrets (some scenarios have it already researched).

Alternatively, it can be opportunistically uninstalled and looted from various world sites.

Material	Steel Cost	Cost	Hit Points	Flammability (%)	Market Value	Beauty
Steel	100	3	120	28	300	-20
Plasteel	40	3 + 60	335	14	740	-20
Uranium	40	3 + 60	300	0	555	-20
Silver	40	3 + 600	84	28	785	-14
Gold	40	3 + 600	72	28	6,185	0

Materials

• Steel is the most viable option early-game, but it's advisable to switch them out for plasteel turrets as soon as you can, as steel turrets aren't very durable and therefore can't withstand sustained gunfire.
• The most effective material is plasteel. It has the most HP, very low flammability, is somewhat easier to obtain mid-late game, and saves steel for other purposes.
• You should expect turrets to be frequently replaced, and uranium is too rare and expensive to be practical.
• Silver and gold are poor material choices due to their poor durability.

Usage

See also: Defense structures#Turrets

Used alone or in small numbers, mini-turrets do not provide much additional firepower. However, raiders will often target the turret instead of the colonists if it is closer to them, shielding the colonists from harm until the turret is destroyed. However, attackers will not take an unpowered turret as a primary target. The firepower of the turrets adds up when massed together, to the point where turrets alone can sometimes beat back even massive raids. Larger colonies often build a "killbox": An entrance area designed to funnel raiders where turrets can do maximum damage while the raiders' own ability to fight back is minimized. Using sandbags to protect your turrets can be a solid tactic in either case. Raiders with long ranged weapons can snipe mini-turrets from outside its range, so forcing them into close range with walls or terrain is recommended.

Turret explosion

Radius of mini-turret explosion visualized.

Turrets have a 50% chance to explode when it reaches 20% health. The exploding turret will spark and emit a hissing sound shortly before exploding a few seconds later. All nearby raiders will run in an attempt to get out of the blast radius to keep their skin intact.

The explosion deals 400 damage to walls, 200 damage to all others structures and furniture, 50 damage to the slag chunks and components that drop, and around 50 damage across multiple body parts to all pawns unlucky enough to get caught in the explosion. Due to this, it's best to space out groups of turrets so that one exploding doesn't create a chain reaction. This is somewhat less of a risk with Plasteel turrets.

Version history

Prior to Beta 19, it used to be called the Improvised turret. It also used more power (350W) and costed more to build, but did not require barrel changes.

In 1.1 it was nerfed to fire a 2-round burst, down from 3.
