Welcome to my 100% Achievement Guide for Ghost Files (MOAC)!
(Note, When there is no commentary in the video, i had to mute for copyright reasons)
This is for, of course, not skipping any mini games at all.
For the most part, mini games are easy in this game but one may give you a headache.
That one is in chapter 3, when you are locked up in Murphys office and have to picklock your way out with 3 paper clips.
three cogs, only 2 rotate when you hit certain ones, sadly, for me it seemed to be a case of keep hitting and trying and as you get nearer, you then start figuring out a little more of what to do.
It is just one of those tricky ones where you can't rteally have a good tactic for it sorry!
As long as you don't hit the skip button in the bottom right corner, you will get this at the end of chapter 6 when disabling the bomb.
Edit - Thanks to Naberios for this.
The 3rd hair/DNA minigame IS MISSABLE.
So i advise to follow the video to make sure you get all minigames to be able to complete this!
Hope This Helps!
