Generally at the E3 expo, if publishers haven't shown much of a new game, they won't permit press to video gameplay footage directly off a demo screen unless is in the background of an interview or similar, but some always seem to unwittingly slip through unaware and today a good 25 minutes of gameplay from the freshly announced Beyond: Two Souls has surfaced on Youtube.

The shakey-cam video offers a long chunk of gameplay from Heavy Rain developer Quantic Dream's next story-driven adventure, starring a mo-capped Ellen Page and shows improved graphics and more of the very liberal use of quick-time events that we've come to know from them. Watch the embed below.

Beyond: Two Souls is due in 2013 exclusively for PlayStation 3.
