If you have ever played Fallout 3, exploring the abandoned metro-tunnels infested with ghouls who want to eat your flesh, this audio will resonate with you personally. As it did with me.

Tommy and Ianto are amazing in this audio together. The ending is beautiful. For me, there's literally nothing wrong with this audio. It's perfection.

And the background music/soundtrack being directly comprised of sounds you'd usually hear in subway tunnels~ it's just beautiful.
