Hey Guys And Gals, Here is my 100% Achievement Guide & Full Walkthrough for Wailing Heights!
So this is for basically completing the tutorial.
You start off playing one of the band members in a police station and have to go through various things like...
How to talk to someone, how to move, how to pick items up etc etc.
Your normal tutorial stuff.
Once you complete this tutorial, you then switch over to "Soul Ghoulman" the Lawyer your speaking to who can turn into a ghost with the "X" Button.
Once you leave the interrogation cell, this unlocks!
Hope This Helps!
