−
The '''mini-turret''' is a stationary defense mechanism which automatically fires at any enemies entering its range of 24.9 tiles. It fires a 2-round burst with no need for warmup, has a slow 4.8 second cooldown and 96% per-tile accuracy. Mini-turrets are somewhat underwhelming on their own, and need to be placed in large numbers to be effective. In earlier versions like v1.0, the mini-turret did not receive a Cover bonus from being hidden behind cover-granting objects like sandbags, however by v1.2 this has been reinstated.

Mini-turrets have a 50% chance to explode when damaged below 20% health. The exploding turret will spark and emit a hissing sound for {{Ticks|240}} before exploding, dealing 50 [[Damage Types#Bomb|Bomb damage]] in a 3.9 tile radius centered around the lower left tile of the turret. Bomb damage is multiplied 8x against [[wall]]s, 4x against other impassable structures and plants, and 2x against passable buildings.

* 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.
+
A single turret isn't much firepower. Each mini-turret is roughly equal to a good [[short bow]] or normal [[recurve bow]] shot with 8 Shooting skill. Even when massed up, turrets are unlikely to handle raids on their own. But they can be useful.
−
* The most effective material is plasteel. It has the most HP, no flammability as of v1.2, is somewhat easier to obtain mid-late game, and saves steel for other purposes.
+
* In large numbers, turrets do add up. A group of turrets, ''when combined with colonists'', can make a meaningful difference.
−
* You should expect turrets to be frequently replaced, and uranium is too rare and expensive to be practical.
+
* Mini-turrets are great as decoys. If a turret is closer to an enemy, enemies will often target it over your colonists. It's better for a [[doomsday rocket launcher]] to hit a turret than a colonist. Turning a turret's power off (such as with a [[power switch]]) will prevent [[manhunter]]s from attacking them.
−
* Silver and gold are poor material choices due to their poor durability.
+
 
 +
: Turrets can also be used as explosive bait. While [[IED trap]]s are generally more efficient, a turret that happens to explode will severely damage any enemy in melee range.
 +
 
 +
[[Killbox]] structures are natural fits for turrets. Killboxes funnel enemies into 1 place, allowing you to take full advantage of your turrets' firepower. In a killbox or not, you'll want to place turrets at least 4 tiles apart. Otherwise, a single explosion can cause a chain reaction, and destroy all your mini-turrets.
 +
 
 +
Enemies that are ''unusually clever'', as well as [[sapper]]s in general, will try and avoid a turret's line of sight. While this might seem like a bad thing, a lategame colony can place mini-turrets where you ''don't'' want sappers or breachers to go. Even if your main killbox uses turrets, you can place another, turret-less killbox near your colonist's bedrooms in order to lure sappers in.

* Steel is the most viable option early-game, but steel turrets aren't durable and won't survive sustained firepower.
 +
* The most effective material is nominally plasteel. It has the most HP and is non-flammable. However, it is relatively high cost and is typically in high demand in armor, bionics, etc. Uranium is commonly received as a quest reward and is significantly less in demand, while offering similar performance.  
 +
* As mini-turrets only require {{Icon Small|Stuff||{{P|Resource 1 Amount}}}} [[stuff]], the cost of upgrading is relatively minor. Not including work to build, uranium only increases the cost by {{Icon Small|Silver||{{#expr: {{P|Resource 1 Amount}} * ({{Q|Uranium|Market Value Base #}} - {{Q|Steel|Market Value Base #}})}}}} while making the mini-turret significantly less likely to be destroyed. If the upgrade prevents destruction a single time, it has more than paid for itself. Should mini-turrets be retained past the early game, it is strongly suggested to upgrade them to uranium. Notably, either Uranium and Plasteel are required to withstand a single standard explosion without destruction, and the effect of the chance to wick at 20% health further incentivizes higher HP pools.

−
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 "[[Defense tactics#Killboxes|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.

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.

The mini-turret is a stationary defense mechanism which fires at incoming enemies.

Acquisition[edit]

Mini-turrets can be constructed once the Gun turrets research project has been completed. They require Stuff 30 Stuff (Metallic), Steel 70 Steel, Component 3 Components, 1,800 ticks (30 secs) of work, and a Construction skill of 5.

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

Summary[edit]

The mini-turret uses the mini-turret gun weapon. In addition to the weapon's accuracy, the turret itself has a per-tile shooting accuracy of 96% or equivalent to a Shooting skill of 8. It fires a 2-round burst, with no need for warmup, but with a slow 4.8 second cooldown. It has a maximum range of 28.9 tiles.

After firing 60 rounds, it needs to be reloaded with Steel 80 steel by a hauler. This can be adjusted in the storyteller settings, but all default difficulty settings do not alter this.

Mini-turrets do benefit from cover, following the usual rules of adjacency and angle. The long standing bug regarding this mechanic has since been resolved as confirmed through empirical testing.

Like all turrets, they cannot target enemies through blind smoke and are temporarily disabled by sources of EMP, with downtime scaling to the EMP damage dealt. Unlike mechanoids, turrets do not adapt to EMP and thus can be continuously restunned.

Visualization of effective turret range of all three turrets, from uranium slug turret (top), to autocannon turret (middle), to mini-turret (bottom).
Green is 80 - 100% of peak accuracy, blue is 50 - 80% of peak accuracy, red is below 50% of peak accuracy and grey is outside range. Gold tiles are spaced every 5 tiles. Values from 1.0.
Per-tile shooting accuracy isn't concerned in these accuracy values.

Explosion[edit]

Mini-turrets have a 50% chance to explode when damaged below 20% health. The exploding turret will spark and emit a hissing sound for 240 ticks (4 secs) before exploding, dealing 50 Bomb damage in a 3.9 tile radius centered around the lower left tile of the turret. Bomb damage is multiplied 8x against walls, 4x against other impassable structures and plants, and 2x against passable buildings. All nearby raiders will attempt to move out of the blast radius before detonation.

Analysis[edit]

See also: Defense structures#Turrets

A single turret isn't much firepower. Each mini-turret is roughly equal to a good short bow or normal recurve bow shot with 8 Shooting skill. Even when massed up, turrets are unlikely to handle raids on their own. But they can be useful.

  • In large numbers, turrets do add up. A group of turrets, when combined with colonists, can make a meaningful difference.
  • Mini-turrets are great as decoys. If a turret is closer to an enemy, enemies will often target it over your colonists. It's better for a doomsday rocket launcher to hit a turret than a colonist. Turning a turret's power off (such as with a power switch) will prevent manhunters from attacking them.
Turrets can also be used as explosive bait. While IED traps are generally more efficient, a turret that happens to explode will severely damage any enemy in melee range.

Killbox structures are natural fits for turrets. Killboxes funnel enemies into 1 place, allowing you to take full advantage of your turrets' firepower. In a killbox or not, you'll want to place turrets at least 4 tiles apart. Otherwise, a single explosion can cause a chain reaction, and destroy all your mini-turrets.

Enemies that are unusually clever, as well as sappers in general, will try and avoid a turret's line of sight. While this might seem like a bad thing, a lategame colony can place mini-turrets where you don't want sappers or breachers to go. Even if your main killbox uses turrets, you can place another, turret-less killbox near your colonist's bedrooms in order to lure sappers in.
