Judging by how few views this radio play has I'm going to assume you've never even heard of it. Which is a shame because--unlike the game--it's good!
Staring Gwendoline Christie, Michael Ironside, Same Littlefield, Kevin Durand, and others.
It's only 4 short 27 minute episodes, but still packs more story than the game does. It's worth a listen. Hopefully the games sequel is better, and that we get more radio plays like this.
