Is this where you get the demo code?

Quantic Dream's highly anticipated murder mystery Heavy Rain hits the shelves on February 24th, and the demo is set for release on PSN on the 11th. But hey, why wait?As part of its Four Days Challenge promo, Sony has released a Heavy Rain "alternate reality game." Those who took part in the promo and successfully discovered the four pieces of evidence can surf on over to the Precinct 52 website and enter the answers they acquired to receive the demo code. However, if you didn't take part in the promo (or did but couldn't solve the puzzles), you can still play the alternate reality game and unlock the code.That, or we can just give you the four pieces of evidence to enter at Precinct 52 right now:Redeem the demo code and you'll unlock two playable sequences. Sorry, you'll have to buy the full game to play those much blogged-about shower scenes.It appears the biggest mystery you'll have to solve is how to get into Precinct 52. The site has been swamped since news of the early demo hit the tubes.
