The '''mini-turret''' is a stationary defense mechanism which fires at incoming enemies.
 
  
== Acquisition ==
+
The '''improvised turret''' is a stationary defense mechanism which fires at any enemy pawns which enter its firing range. It will automatically target any [[raiders]] or [[Animals|psychotic animals]] which enter within a 25.9 tile radius around the turret. The turret is a 3-round burst weapon which has no warmup time required to fire, but has a woefully long 5.15 second cooldown period after firing. While turrets are somewhat underwhelming on their own, large groups of turrets are able to incapacitate or kill hostiles within seconds.
Mini-turrets can be constructed once the [[Research#{{P|Required Research}}|{{P|Required Research}}]] research project has been completed. They require {{Required Resources}}, {{Ticks|{{P|Work To Make}}}} of work, and a [[{{P|Skill 1}}]] skill of {{P|Skill 1 Level}}.
 
  
Alternatively, turrets can be uninstalled and looted from various world sites.
+
In order to construct Improvised Turrets, you need to research [[Research#GunTurrets|gun turrets]], which in turn requires [[Research#MicroelectronicsBasics|microelectronics basics]] to be researched. Gun Turrets is pre-researched if you choose to start off with the 'Rich Explorer' scenario, and you can also implement Gun Turrets as a starting research in a custom scenario.
  
== Summary ==
 
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 {{P|Range}} tiles.
 
  
After firing 60 rounds, it needs to be reloaded with {{Icon Small|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.<!-- This bug was, as mentioned, long standing, but also had been claimed to be fixed several times and had a number of compounding factors confusing the issue, such as displaying a non-existent accuracy penalty. Leave the clarification in for the near future - Harakoni -->
+
==Tactics==
 +
Used alone or in small numbers, 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.
  
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.
+
When building a turret, there's a 50% chance that it will never explode; regardless of what amount of health it's at. Normally; a turret will spark and emit a hissing sound that increases in pitch, once it drops to or below 20% of its maximum HP (e.g. a Steel Improvised Turret will begin hissing at 20/100 Hit Points), and explode a few seconds later. When a turret's about to explode, all nearby raiders will run in an attempt to get out of the blast radius to keep their skin intact.

+
When a Turret explodes; it does 200 damage to all structures within its radius, 50 damage to the slag chunks and components that drop, and typically 12-36 damage (with variances in increments of 4 points) to all pawns unlucky enough to get caught in the explosion - but it will sometimes do 48 damage too.
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.<br>
 
Per-tile shooting accuracy isn't concerned in these accuracy values.]]
 
  
=== Explosion ===
+
===Example of an Explosion===
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. All nearby raiders will attempt to move out of the blast radius before detonation.

== Analysis ==
 
{{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.
+
''The turret's now at 20 HP and begins to spark and hiss - Trogo's in danger.'' <br>
* In large numbers, turrets do add up. A group of turrets, ''when combined with colonists'', can make a meaningful difference.
+
[[File:TurretSparking.png|200px|Turret is now sparking]]
* 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.
 
  
: 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.
+
''The turret has now exploded: Trogo's wounded, structures are damaged - all hell's let loose. Took several screenshots and merged them into one image to demonstrate the full extent of the damage.'' <br>
 +
[[File:ExplosionDamagesEdited.png|439px|Turret has now exploded]]
  
[[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.
+
==Materials==
 +
Naturally, Turrets come in 5 flavours: Shocking Steel, Perfect Plasteel, Unaffordable Uranium, Stunning Silver, and Glorious Gold. Regardless of what material's used; turrets will always give out -60 beauty - so don't even consider building your turrets out of Gold, or even Silver; they'll have more of an impact on colony wealth (therefore increasing the size of raids), while doing less for you by having less Hit Points.
  
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.

* 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.

The most effective material to use which is also worthwhile is naturally Plasteel: It has the most HP, very low flammability, is somewhat easier to obtain mid-late game, and saves Steel for other things (e.g. power generators, weapons) - especially as you should expect Turrets to be frequently replaced, and Uranium is too rare and expensive to be practical. 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.
* [[Version/0.2.363|0.2.363]] - Made turret look and sound weak to match its functionality.
+
 
* Alpha 3 - '''Auto-turret''' renamed to '''Improvised Turret'''.
+
 
* [[Version/0.19.2009|0.19.2009]] - Renamed from '''Improvised turret''' to '''mini-turret'''. Power decreased from 350W and cost decreased, but now requires barrel changes.
+
[[File:SteelTurret.png|200px|Steel Improvised Turret]]
* 1.1 - Nerfed to fire a 2-round burst, down from 3.
+
[[File:PlasteelTurret.png|200px|Plasteel Improvised Turret]]
* [[Version/1.1.2569|1.1.2569]] - Range increased from 25 to 29.
+
[[File:UraniumTurret.png|200px|Uranium Improvised Turret]]
* [[Version/1.1.2618|1.1.2618]] - Reload cost was doubled and the fuel capacity was halved, while the damage was increased to 11 from 10.
+
[[File:SilverTurret.png|200px|Steel Improvised Turret]]
* [[Version/1.3.3200|1.3.3200]] - Damage increased from 11 to 12. Accuracy increased: touch 0.7 -> 0.77, short 0.64 -> 0.7, medium 0.41 -> 0.45, long 0.22 -> 0.24. Turret ammo cost is no longer factored by difficulty (previously: Adventure Story and below reduced cost).
+
[[File:GoldenTurret.png|200px|Golden Improvised Turret]]
* Between [[Version/1.3.3117|1.3.3117]] and 1.4.3580 - Turrets now properly benefit from [[cover]]. Despite displaying in the mouse-over box as such, empirical testing demonstrated that mini-turrets did not benefit at all.<ref>https://i.imgur.com/mq4aojR.mp4</ref>
