Hey Guys & Gals!
Here is my 100% Achievement Guide for APTI!
At the beginning of chapter 8, Hugo will ask you to follow him downstairs.
Follow him down the first flight of stairs, but DO NOT follow him into the next room.. Instead, take a right down more stairs and Hugo will join you.
At the bottom, go to the left down more steps and you find the tomb.
You can visit here later on BUT It is the conversation with Hugo which is required to unlock this.
So best bet is to get this done immediately at the beginning of chapter 8!
Go to 17:30 in my Part 2 Video to see where and how this is done.. Or if you prefer a solo video for it, that is also below!
Hope this helps!
