Just saw it today. I have to say that it contrasted with my early impressions of a clean, white and futuristic-looking metropolis. Now it appears that the whole thing takes place inside a coccoon city (called Coccoon) that seems to be dark and rather dingy, with fluro lights and a huge suspended train network that delivers stuff, baddies and the occasional boss that comes mounted to the track. Also you seem to be part of some sort of gureilla faction fighting the governerment. The only thing which I seemed to have got down pat is the gun/sword combination thingy that looks rather cool.
