I'm pretty sure that it's been mentioned here before, but I can't seem to find a particular game that I'm not even sure is very far in development. It's set in more modern times, I believe. I seem to recall there being some videos on YouTube that showed off various features of the game engine, including snow effects and filter effects that're used in real-time during game play. I can't remember the title of the game, although I'm pretty sure that it was an abnormal spelling of the word 'vampire' or something. Any help?
By the way, the snow effects video featured the main protagonist standing on a moving train. Also, the game seemed to have a military theme to it.
