Mods appearing for Silent Hill 2 was just a matter of time, and among the first is one that completely removes the fog from the town. While much of the atmosphere is obviously lost, it also highlights the enormous graphical effort put into this remake. Another mod recreates a sign in the game that, in the 2012 HD Collection (of Silent Hill 2 and 3), used the Comic Sans font.
In fact, the game without fog looks really impressive. So experiencing it as intended first, and then returning for a second round without the fog, might be a good idea.
