This guide was made because I loved the game and wanted everyone to have fun exploring it. Unfortunatley, some of the more obscure achievements took me a while, but I did find a lot of tips and tricks in the community. So here it is, my %100 guide. I WISH YOU ALL JOY!
 

Story Related (Not Missable)

• Missing and Returned – To achieve this achievement, you will need to locate Quaraff's little girl.

 
 

• Get Lost – Die for the first Time (In the found state it is much easier to get, but I recommend skydiving into an unknown).

 
 

• Gone and Discovered: Find the Quaraff mother to reunite her with her daughter.

 
 

• Lost and Found: Find the Quaraff father and reunite your family.

 
 

• There is a way out: Play the video and find out the truth about this facility.
