Introduction[]
Falling to Pieces is an Infinite mode achievement in Run 3.
Suggested Character: 
Note: This achievement only appears when you have bought/earned the Duplicator.
Gameplay[]
There isn't much of a strategy to this. One tip is to just normally run in Infinite Mode using the Duplicator without concentrating on having duplicates fall. Another way is by going behind a box and have the Duplicator spawn duplicates, and move to the sides. This way, if a duplicate is spawned and you move left, it will go further if it's not behind the box, thus, eventually falling and giving you progress on the achievement.
Trivia[]
The name is most likely a reference to the song "Falling to Pieces".
