This is great stuff lads. Thing that strikes me most is the ambience and atmosphere. There's a great attention to detail in the surroundings and the background, we've got destructable candelabras, barrels. Hallways, stairwells, moving platforms, whip swinging. Swirling smoke, shadows, lightning and fire effects look amazing. The engine looks to be working very well indeed.
Camera struck me as working remarkably well too. Some of those beams you've got to balance and traverse over look to be at odd angles onscreen, but perhaps that's a clever way of adding a bit of difficulty. Platforming in the clock tower looked very Prince of Persia, but I think the whip grappling and swinging works well and adds another dimension to it. Love with the whip, that you can swing out from a vertical wall. I agree with OSM that the clock tower looked a bit slow to begin with, but we've got death pits and some consequential platforming: thought required to nagivate/advance so I'm all for it.
We've now seen combat in the mix of roaming around, and that's vastly reassuring. This game is going to be legendary for the series.
