How to unlock the The Thin Veneer of Civilization achievement in Alone in the Dark - Definitive Guide
Immediately after killing two monsters during your time at The Hateful Mound in Chapter 2, you'll be presented with a barrier. Simply smash it up by swinging any melee weapon (there's a shovel and a hatchet nearby, so take your pick), and Robert's your father's brother.
This achievement may as well be story-based as you have to break a barrier to progress through the game. The first one you'll will be in Chapter 2.
There's a couple of boarded up places in the game. Just use a melee weapon to break one open.
