This is a very addicting game.  You play as long as you can survive, die and start over.  What keeps you going is finding out the story, which is really quite interesting.  The music is cool and the voice acting is top notch.  Excellent game. I sunk a LOT of hours into it as a way to unwind after a long day of work. 

Pretty inexpensive too.  And it's on all platforms, I think.

worth checking out!
