The '''uranium slug turret''' is a defensive turret with very long range and shot damage, but with a wide blind zone.

== Acquisition ==
Uranium slug 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}}.

== Summary ==
{{Image wanted|section=1|reason=Concise, small infographic of the cover bug}}
The uranium slug turret uses the [[uranium slug cannon]] weapon. In addition to the weapon's accuracy, the turret itself has a per-tile [[shooting accuracy]] of 98% or equivalent to a [[Shooting]] skill of 14. It has a maximum range of {{P|Range}} tiles, but is unable to hit enemies within an {{P|Minimum Range}} tile radius. These ranges are centered on the lower left tile of the turret, regardless of orientation.  Despite its damage, the uranium slug turret's stopping power is almost non-existent, not even being able to stagger [[human]]s - the same is also true for the [[autocannon turret]]. 

After firing 30 slugs, it needs to be reloaded with {{Icon Small|Uranium||60}} [[uranium]] by a hauler. This can be adjusted in the [[storyteller settings]], but all default [[difficulty]] settings do not alter this.

Since uranium slug turrets are large 2x2 structures, ranged attacks are twice as accurate against them.

As of [[Version/1.4.3580|version 1.4.3580]], uranium slug turrets do benefit from [[cover]] but only if the lower left corner of the turret is covered from the shooter as confirmed by [[:File:Big_turrets_partially_benefit_from_cover.jpg|empirical testing]]. In practice this means that the turret can '''only''' be in cover if engaged from the south-east, as pawns will target the nearest tile of the turret and cover only applies if it is directly adjacent to the targeted tile. 

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.

=== Explosion ===
Uranium slug 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 5.9 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 ==
{{Stub|section=1|reason=Exploiting/avoiding the cover bug in killbox/defense design}}
Uranium slug turrets are expensive, with high research requirement and high ammo costs. Getting enough [[uranium]] to use the turrets is difficult, at least until you have either [[ground-penetrating scanner]]s or [[long-range mineral scanner]]s. In return, they don't offer much firepower. Turrets in general aren't strong - you should not expect them to defeat raids on their own. In any case, [[autocannon turret]]s are often the more practical choice.

Autocannons are cheaper, yet have better raw {{DPS}} - to the vast majority of targets - until past 25 tiles of range. Also, the uranium slug turret has a tendency to overkill. It deals 55 damage per shot, but a human's largest body part, the torso, only has 40 HP. This leads to wasted overkill damage. Thus, even against armored humans, the autocannon may outperform. Against [[centipedes]] and other heavy mechanoids, the uranium turret ends up being stronger, due to higher {{AP}} and lack of overkill damage.

The real niches of the uranium slug turret are its massive range and {{AP}}. With 45.9 tiles of range, it outranges every enemy in the game. Unlike most weapons, this turret gets more accurate the further away a target is, becoming strongest around 35-45 tiles.

Due to their impracticality, uranium slug turrets are relegated to the late-game / end-game, where the uranium cost is no longer an issue. It performs great against high-armor targets from far away. Since uranium turrets are most accurate from far away, you'll want to design any [[killbox]]es around that fact. Give space to place your turrets, but place them out of line of your colonists to avoid [[friendly fire]]. Also, due to their range, uranium turrets remain effective outside of a killbox.

== Version history ==
* [[Version/0.19.2009|0.19.2009]] - Added.
* [[Version/1.1.0|1.1.0]] - Received a massive nerf to damage (75 -> 30), nerf to armor penetration (112.5% -> 70%), reduced range (49.9 -> 39.9), increased reload cost (60 -> 80 baseline) and nerf to shooting accuracy (98.8% -> 98%).
* [[Version/1.1.2618|1.1.2618]] - Received a buff to damage (30 -> 45), increased range (39.9 -> 45.9), increased reload cost (80 -> 120) and reduced magazine capacity (40 -> 30).
* [[Version/1.1.2624|1.1.2624]] - Received a buff to damage (45 -> 50), buff to armor penetration (70% -> 75%), and reduced reload cost (120 -> 90).
* [[Version/1.3.3200|1.3.3200]] - Damage increased from 50 to 55. Accuracy increased: touch 0.2 -> 0.22, short 0.3 -> 0.33, medium 0.4 -> 0.44. Turret ammo cost is no longer factored by difficulty.
* Between [[Version/1.3.3117|1.3.3117]] and 1.4.3580 - Turrets now benefit from [[cover]]. Despite displaying in the mouse-over box as such, empirical testing demonstrated that turrets did not benefit at all. However, a new issue was introduced. See above.
