I love when you get under a Timefall Shelter and *that* song just plays. *That* song that just compels you to sit under the thing and relax, as you gaze upon the devastated and desolate landscape of post-apocalyptic America.
I was walking down a mountain after a harrowing trek through BT territory. Then a low roar song comes on as I'm headed down the mountain. The delivery was what solidified the game as amazing for me.
