I'm trying to recall a NES game that I rented as a kid.
I really don't recall much about it. I was sick that weekend and hardly played the game, and what I recall must be viewed through the haze of burning fever and throwing up every hour. :P
I can recall that you played as a warewolf, and could climb on walls and the like. The game also came with a comic, that set up the back story -- a NASA scientist on a vacation in the west unlocked an anicent evil spirt by accident, and he used his influence to have a shuttle spread some kind of mutant goo over the world, taking it over. The main charcter was a native american able to harness the powe of the wolf and set out to stop him.
I'd like to try it again, with a emulator and save states (as I recall it being a hard game) but that's about all I can recall of it.
