After playing through all the difficulty levels I now replay RAGE for the 5th time to get the obsessive compulsive achievment. I play it on normal because on nightmare I couldn't finish the sniper missions. Now normal is so easy that I started using only the fists (and some hand grenades). I'm at the well now, and there were only a few situations where the fists didn't work (the giant mutant, shrouded minigun). Did anybody else try a fist run, and on which difficulty? Which situations did you find impossible to do with the fists?
