Mini-turret

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. Each requires 30 Stuff (Metallic, 300 for SMVs), 70 Steel, 3 Components, 1,800 ticks (30 secs) of work modified by the construction speed of the builder and the work to build factor and offset of the material, and a construction skill of 5.

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

Summary[edit]

Mini-turrets automatically shoot at enemies within range so long as they are powered and have sufficient ammunition. They only shoot at enemies of their faction, including manhunting animals but not animals hunting pawns or faction animals for food. They are capable of friendly fire. 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 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.

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]

Material[edit]

You should expect turrets to be frequently replaced.
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 30 stuff, the cost of upgrading is relatively minor. Not including work to build, uranium only increases the cost by 123 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.

Version history[edit]

0.2.363 - Made turret look and sound weak to match its functionality.
Alpha 3 - Auto-turret renamed to Improvised Turret.
0.19.2009 - Renamed from Improvised turret to mini-turret. Power decreased from 350W and cost decreased, but now requires barrel changes.
1.1 - Nerfed to fire a 2-round burst, down from 3.
1.1.2569 - Range increased from 25 to 29.
1.1.2618 - Reload cost was doubled and the fuel capacity was halved, while the damage was increased to 11 from 10.
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).
Between 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.^[1]
