Papa Sangre is a surround sound mobile game that guides players through a virtual thriller maze with the aim of saving a loved one. According to the website:
Papa Sangre is a video game with no video. It’s a first-person thriller, done entirely in audio by an award-winning team of game designers, musicians, sound designers and developers. We’ve created an entire world using the first ever real-time 3D audio engine implemented on a handheld device. Which was BLOODY HARD.
To visit this dark and mysterious palace, players will only need an iphone, functional earphones and...their imagination. Check out this video to get a snippet of what the game sounds like:

I think it's brilliant idea. I haven't had the opportunity to watch the video in full because of my internet connection but I am guessing the game will be even more fun when played in a group, as shown during their first playtest.
