Uranium slug turret

Uranium slug turret

An armor-piercing turret. Its ultra-dense uranium shells can punch through heavy armor, but it requires new uranium slugs to be loaded after use. It's more accurate at longer ranges, and can't fire at all close up. May explode when damaged.

The uranium slug turret is a defensive turret. It has a long range of 45.9 tiles and is very accurate at range (98% accuracy per tile vs 96% for all others), but can't hit anything within 11.9 tiles. It is more accurate at long ranges than at close ranges. Like the autocannon turret though, the uranium slug turret's stopping power is almost non-existent despite its extremely high per-shot damage, not even being able to stagger humans. It can destroy arms and heads in a single shot. Useful against Centipedes and other tanky units (such as ones wearing power armor) because of its high Armor Penetration.

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

It is built with Steel 300 Steel, Plasteel 30 Plasteel, Uranium 60 Uranium, Component 6 Component in 15,000 ticks (4.17 mins).

After firing 30 slugs it needs to be reloaded by a hauler, costing:

  • Uranium 60 uranium in Peaceful and Base Builder difficulty
  • Uranium 90 uranium in Medium difficulty
  • Uranium 120 uranium in Rough difficulty and above

Its high armor penetration negates much of the armor points from any enemy.

Uranium slug turrets have a chance to explode when they drop below 20% health, dealing damage to everything in a large radius.

In the current version, it is too cost-inefficient to be practical against the majority of enemies- uranium is hard to come by, and the damage, while high compared to other weapons, is not enough to compensate for the cost.

Interestingly, it is more accurate at long ranges than short ranges; for best effects, pair it up with the other turrets to provide short-range firepower.

It works well to intercept heavily armored enemies, such as centipedes or raiders with marine armor as its extremely high armor penetration will negate much armor. However, due to its low accuracy at short distances it is unsuited for killbox use without a specially designed killbox.

Unlike the mini-turret, this one can not be moved after it is built.

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.

Cover bug

As of version 1.3.3117, despite displaying in the mouse-over box as benefiting from cover, empirical testing demonstrates that this is false and uranium slug turrets do not benefit from cover at all.
