Didn't much like the trailer, I find it very difficult to connect to the narrative - never played the original for obvious reasons and I should imagine there's many others like me, I respect the whole 'dropped in to the action' approach' but I'd prefer a trailer to introduce the Helghast and explain it all a bit more, are they human? why's everyone fighting? hard to get excited without knowing the context.
That said, animations are incredible - especially liked the bit where the bloke turns the corner on the gantry and slips to the side while running, fantastic to see a developer spending so much time on animation.
