Interesting game concept in that you (allegedly) can occupy any/most character/s in the game world. If you get killed; your character is perma dead; you move on to occupy a new character that you select: NPCs (potential player characters) each have rudimentary back stories and special skill sets.
I played the E3 demo at the Ubi Lounge at E3, found it really neat! Though I had to use a controller, I'd have preferred a keyboard & mouse. I'm no controller hero but still it was exciting nonetheless (perhaps even more so, I kept screwing up the controls and turned stealth into guns blazing. "Let's take them out quietly. Oops, that threw a grenade." ).
