This was an incredibly difficult game. I read on wikipedia it was made easier for the American version which is scary.
Still, it was one of my favorites, even if I could only beat it with the help of a game genie.
I spent a summer playing it, and just loved the maps, weapons, and bad guys (basically Purple Nazis called Badds, which were called Nazis in the Japanese version).
So when I saw there was new one coming out, I got pretty pumped. Lets just hope it does justice to the name.
