Assassin's Creed TGS: Climb the hell up that tower

This game is gorgeous, breathtaking, and making be a bit ill :). I need this game right this goddamn second and I can't wait any longer for it. The video shows off some of the gameplay, and for the first time its not by some presenter it's literally some people playing it on the show floor being recorded by video camera, first thing he does is climb to the top of some like cathedral tower and just sits on top of it like a god haha. Then we see him running about and getting into trouble with the authority, they fight a bit and he almost dies, but I have to note the feature of what seems to be rechargeable health, If you notice our lead man is very close to death and backs out of a situation and a couple of seconds later some of his health is restored before he starts getting attacked again. Anyway just enjoy the damn video and be mad that your not playing it:
