Ok, around 1998 - 2002 I remember seeing this video demo for an FPS game and I have no idea what it is, but it stuck in my mind and I wanted to see it again.

Scene:

It was snowy, with lots of huts and primitive houses and I think mountains in the immediate background, like some kind of town in alaska and the whole intro was played through the scope of a sniper rifle (which I think became apparent at the end which made it cool), so initially it was zoomed it on a target in a hut, then it zoomed out over a period of about 20 seconds across the city (was impressive in scale), before it showed the sniper pulling the trigger and the initial target was shot. The target MIGHT have been in a guard tower.

There was some eerie, low key music, and dogs barking. I also think it was at night.

Does anyone know what it was called?
