Hidden video files?

I was browsing inside MW2's game files and came across the video folder (inside main). I noticed they were in .bik format so I install RAD Video Tools. I went through most of the video files and noticed that the CoD4 Title Logo was in there (title.bik). I also found default.bik which looked like the old IW logo but I don't know since MW2 was my first CoD game. There was 1 last very interesting thing, what in the world is attract.bik? I looks like a trailer for a game but I don't know what game it is... any ideas?
