THIS IS AN UNMISSABLE ACHIEVEMENT!!!
I'm not going to post at what point you obtain it though. Spoilers can accidentally be read by the wandering eye...??
P.S. All of the Achievement Guides I've posted for this episode have the same solution word for word. In 2 hours, you will obtain the full 100G.EDIT: I now need to add some sort of description of the unlocks to all of my solutions now
