The Dark Pictures Anthology: Little Hope

This trophy unlocked at the end of my Head playthrough, so I recommend going for it during that playthrough to ensure it works the same way. Once you escape the ruined house near the end of the game, you'll get a cutscene where you're confronted while walking on the road. Once the scene ends, the trophy should unlock.

The specific ending I got that unlocked the trophy may depend on having found the gun in the Off Track chapter and keeping it with you throughout the game. I believe as long as Andrew survives the events of the game, this trophy will unlock.
