From the studio that brought you Heavy Rain (one of my favorite games), Quantic Dream has released a short called "Kara". They released a short in 2005 called "The Casting" and gave us a bit of insight of what to expect in Heavy Rain. This new short definitely explores new possibilities and avenues, but it is uncertain whether it'll be connected to their next game.
The short itself is actually pretty good and emotional. Check it out! Slightly NSFW.
