I found these guys a few months ago. They created a modern day radio show with real voice actors, quality sound effects, and a good old fashioned horror story. I was hooked after listening to Chapter 1 and blew through all the other episodes in like 2 days. It' s about 3 off duty soldiers at the beginning of a Zombie apocalypse. They find a few survivors and try to hold up in an apartment building. These aren't ordinary zombies either. I don't want to spoil it but there's some really crazy stuff happening in this show. It's worth a listen if you like horror.
It's free to download off iTunes and Zune, or stream it straight off the website.
