Silent Hill threatrical trailer hits the web

[Great Rumbler]

I still don't know if those strange gas masked people are supposed to be from the outside world or are some sort of crazy bad guy, but I'm thinking the latter because the main character hides from them.

They're miners. Read this: http://en.wikipedia.org/wiki/Centralia%2C_Pennsylvania

Is the air raid siren predicting a change in the world, or not? In that preview, you WANT that to be the case, but it's just as likely that someone intentially set it off to get all the survivors to run to that place they are all cramming into in the preview.

I doubt that bring something like that from the first game and then turn around and use it in a completely different way. Also it's right after that that they have the scene where everything turns, also Cybil says "It's" coming. It perhaps being the monster [or whatever] that makes everything change as some have conjectures, or the change itself coming.
