what are your first impressions?

I thought the graphics were stunning, probably the best I've seen on the 360.

The AI seems pretty decent on both sides - i.e. the foxy lady sidekick kept healing me when I was getting battered and even gave up some of her ammo. Plus, the zombie people were relentless, even when I climbed up to the top of a building they still followed me, despite me thinking there was only 1 way up.

I couldn't handle the controls though. Took me ages to work out how to draw the knife (hold LB then swing with RT? Get lost!) Can you actually punch people? I was mashing the pad at one point and kept trying to give herbs to zombies by mistake.
