A demonstration of Heavy Rain, that caused such a stir earlier this year, was possibly one of the most impressive we've ever seen. Describing it was tough - you really had to see it. And now you can.
As posters Gamekyo reminds us, the entire demo is playable - after the initial intro cutscene - and even when the camera is taking a cinematic, cutscene-style angle, there are playable aspects to it.
It's in French, but don't let you put you off. Make sure you read our impressions to find out exactly what was going on too.
