Inscryption

To do this achievemet, you must first be in the 2nd part of the Archivist's boss fight. If you don't want to delete aything important, make your own BS text file or something similar (I put it in my Inscryption_Data game folder) Put the new text file in it's own folder just to be safe.

After you have it on the board, destroy it. Whether it be through the hammer, a bomb wipe, or however else you destroy it, just make sure it dies. After she says it's deleted, go back to your folder where you put the file originally. (Make sure the game isn't paused when you tab out or it might not proc the achievement. If you don't know how to check, go to your game settings, particularly your audio. Make sure it isn't on pause when the game isn't in focus) A new text file will be in that same folder by P03, saying they tried to delete it but couln't, and asks you to follow the rules by deleting it yourself. Make sure to delete the ORIGINAL file, not the new one created by P03. You must delete the file before the battle is over, or the achievement won't proc. Once you've fully deleted the file, go through the rest of the boss battle as normal.

After going through the rest of the dialogue - with P03 commenting on your deletion of said file - Voila! Your confusing ass achievement!
I swear, you gotta become a computer engineer for this shit lmao
