The way to get the new secret achievement.
How to Obtain Faraday Malfunction Secret Achievement
You must be on the 1.14 beta version, which you can look up a seperate guide for. The achievement is pretty buggy, this is just how i got it.
Choose the Tower map.
Add the Metal Pole and Jukebox on the top of the tower.
Connect them, like this and then turn the jukebox on.
Move it to the left side of the tower (as seen in the image), and you’ll get the achievement. This step is pretty buggy, some people got it by throwing the jukebox in the air along with other stuff.
(This is the lowest “step”).
