I started playin this game on purist without tryin it on another difficulty first. Crazy shit. Now i cant get past the FOG. I finally saw it played on my friends ps3 and he was playin on normal. Woulda been a lot easier that way but i woulda had it beat in 1 day probly. ANYWAY my point is, if you ever go to play this game. Play it on purist and see how far u can get before you drop the difficulty. Its an awesome game either way.
