A short way into the game you will be given a quest to collect the Mcguffin from the red crystal tower. Once you reach this area and you can see the tower on your left, drop down to the floor and head to the opposite side. You should find a building with a door you cannot open and a red man stood in front of it dressed like Heisenberg from Breaking Bad.
Head onto the roof of this building to find some wooden planks you can break. Break these and drop in to find a makeshift crystal lab. Simply eat one of the crystals out of the pot and the achievement is yours
