Can Em All how to use turrets comes down to two actions: buy the turret node in the skill tree, then place the turret in your factory. There is no aiming and no trigger — once it is placed it acquires living creatures in range and fires by itself. What it does not do is respect walls, judge distance, or refuse to waste shots on a corpse in the way.

Can Em All how to use turrets: buy, place, fire

  1. Unlock the turret node in the skill tree.
  2. Place the turret somewhere in the factory.
  3. Leave it. It fires on its own at any living creature in range.

Turrets and the body-cleaning robot both arrived with the full release. They are convenience features, not the main way to clear a factory.

What turrets track and what they ignore

Three behaviours define them in practice:

  • They track anything alive in range, regardless of what is in the way. A body blocking the line makes the turret spend ammo on it. Load explosive ammo if you want it to punch through a pile.
  • Their tracking degrades with distance. Close targets are handled reliably; anything far off is missed often enough that you should not rely on it.
  • They keep firing at a creature they cannot reach. This one is useful rather than annoying, and it is covered in the next section.

The practical takeaway: a turret placed where creatures walk past it is worth having. A turret pointed across the whole factory is not.

Using turret aim to find a stuck creature

Late in the game, creatures wedge themselves into walls and into the ceiling beams. The game keeps counting them as alive, so the next truck never arrives, and you cannot walk over and finish them.

The turret is how you find them:

  1. Notice a turret pointing at a wall, a corner or the rafters.
  2. Follow its line of sight.
  3. Find the live creature stuck there and kill it.

The truck counter clears once the creature is actually dead, and the deliveries resume. If the angle is impossible, reloading the game also works. The stuck in the endgame guide covers the other two causes of a stalled run.

Whether turrets are worth buying

They are worth it early and less so later. Once you own the rocket launcher, the turret is largely redundant — the launcher clears a truck faster and more reliably than anything that aims itself.

Before the launcher:

  1. Buy one turret and place it near the truck door or the belt.
  2. Let it cover the boring part of a delivery while you do something else.
  3. Replace it with a launcher node as soon as you can afford one.

The order for the weapons that make a turret unnecessary is in the weapon upgrade guide.

The body-cleaning bots

The floor-cleaning bots that came with the same update are much weaker than the turrets. They hardly get any bodies into the grinders on their own, so they are not a substitute for manual work.

Treat both turrets and bots as a convenience layer over a factory you are still running yourself. What actually keeps the factory moving — feed rate, object count, multipliers — is in the production guide.
