Tell Me Why

I unlocked this one trying to open the barn door, near Ronan's house, three times with (thanks BlakManDan)

Here's the location, you can access it from Isolation Mode (via Chapter Selection) in case you missed it:


EDIT: Apparently, this is the only place it works, if anyone got somewhere else please let us know.

This requires you to try to open the same locked door three times in a row. The earliest point is to use the shed door when you arrive at your old family home in "A Big Wooden House". But you can do this with any locked door in Episode 1. You can replay any section of the Episode in Isolation mode without overwriting your story progress.

When you reach the old house (The Ronan's house), there is a barn to the right of it. You have to try to open the locked side door of the barn a few times for it to pop!

Here is a video guide with all the missable achievements! The This Is Despicable Achievement Guide starts at 0:42! The timestamps for all the achievements and collectibles are in the description! Hope this helps!

Here is my 100% Achievement guide for Episode 1 of Tell Me Why.

This is the first missable achievement in the game (although if you do miss it, you can easily chapter select to get back there quick).

After you take a short boat ride with Alyson and her car and have a long convo with her.
You end up outside the Ronan house (Its Obvious as you can't miss it and they explain that its the house)

They try to open the door but its locked.
When you regain control of Tyler again, from the door go left and you see a barn.
Well just right to the barn you see a door, try to unlock that 3 to 4 times with the button and achievement should unlock.

Go to 27:25 in the video to see the exact location of where this is obtainable.

Hope This helps!
