It took a little longer than I personally suspected but the Intro cinematic to the upcoming Heavy Rain has been leaked. Commonly you'd see a spoiler warning on things like this but in all honesty, it's not required. The intro fits rather well I suppose. It's nothing more than people living their lives; It's raining.  That's all there is to it.

The intro fits the game quite nicely, giving it similarities to movies much like the game. The introduction has no plot advancement, no obvious pointing out of important characters, and as said already no spoilers. Just a city which it happens to be raining in. Oddly enough it does seem strange that everyone is very active and mildly cheery (some of them) for the rain.

(Did you catch the "magic truck" at around 2:10 in the video? I know i did!)
