This is a guide on how to get the Unachievable achievement. It clearly states it's unachievable, but it really isn't. Before we start, I just want to tell you that you will need Notepad++ to get this achievement. Do not use Notepad for this, because there are no spaces on Notepad. (Here's the download for Notepad++. https://notepad-plus-plus.org/ ) Ok, let's begin!

Step 1: Once you have downloaded Notepad++, open your Steam library. Right click The Stanley Parable in your games list and select the option that says Properties.

Step 2: In Properties, select the menu at the top of the menu that says Local Files. Once you are in the local files menu, select Browse Local Files. This should take you to the game's files.

Step 3: Go to these folders. Go to the folder named thestanleyparable, then inside of that folder, go to the folder named cfg.

Step 4: Inside the cfg folder, right click config.cfg and select Open with Notepad++ if it has been installed.

Step 4: Once that is open in Notepad++, add a new line at the end of the lines that start with bind, and copy this into the new line: bind "x" "~;_u"
Once that has been copied, save the file. Be sure to set the file to read-only to prevent it from getting reset!

Step 5: Go back into your Steam library, and run The Stanley Parable. Once you are in the game, click Begin the game. When the game starts, go up to something and press the X key. Wait about 10 seconds, and it should say you have unlocked the achievement called Unachievable.

I hoped this helped you, and I hope you have recieved the achievement. But for now, have a picture of Proto, and let him recover your deleted files.
