The autocannon turret is a defense structure that fires a burst of medium-damage shells.

Acquisition

It is built with 350 Steel, 40 Plasteel, 6 Components and takes 15,000 ticks (4.17 mins) to build.

Summary

The autocannon turret uses the autocannon weapon; the turret itself has a per-tile accuracy of 96%, equal to a Shooting skill of 8. It has a maximum range of 32.9 tiles, but is unable to hit enemies within an 8.9 tile radius. Despite its damage, the autocannon's stopping power is almost non-existent, not even being able to stagger humans - the same is also true for the uranium slug turret. After firing 90 rounds, it needs to be reloaded with 180 steel by a hauler. This can be adjusted in the storyteller settings, but all default difficulty settings do not alter this.

Since autocannons are large 2x2 structures, ranged attacks are twice as accurate against them. And as of version 1.3.3117, turrets don't benefit from cover. Despite displaying in the mouse-over box as such, empirical testing demonstrates that mini-turrets do not benefit at all.^[1]

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.

Explosion

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

Analysis

It can be useful in killboxes where it is more likely to hit, by bringing enemies closer together and putting them in range, but otherwise its use is not cost-effective in an open field as its low accuracy makes it unlikely to land shots at range, and it costs quite some steel for each shot.

Due to their damage output, autocannons can be effective at mowing down lancers when grouped, provided you can lure them within its effective range, otherwise the autocannons will have trouble hitting them. Autocannons are also somewhat effective at dishing out damage against large targets such as centipedes since the accuracy bonus from their body size significantly offsets the autocannon's lower accuracy, though centipede weapons can make relatively short work of autocannons too.
