It's going to be very hands on martial arts for most part. Though thinking of maybe turning things into a bit more psychological.... though if I recall right, Silent Hill things want to kill you, right?
yarnzipan: Wu Xin isn't well versed with this sort of psychological situations at all, so he'll be very twitchy. Or there's always the last day action scenes, which seems the easiest to plot.
cannibalherpes: Wu Xin will be constantly on the run and hiding. Since there will either be a hulk chasing after him or a pair of dead martial artists and he can't deal with either at the moment.
The hulk will be hard for a normal person with no powers to deal with. But dead martial artists aren't bad, they won't have their internal force (aka ability that can punch you through 2 brick walls).
magicom: Malcolm tries to be hero and needs to be pulled into escaping as well. Will he approach if he already sees they weren't that normal to begin with?
