To get this achievement you'll need to collect all of the glitching remains that the game has to offer. There are 18 in total throughout the game. 4 in chapter 1, 6 in chapter 2, 4 in chapter 3 and 4 in chapter 4 (there are none during the final chapter). Here is my own video guide which shows the location of all of the glitched remains along with all of the other achievements the game has to offer.
