Due to concerns from Nintendo of America, the Super NES version was heavily edited as well. All swastikas and Nazi references were removed. Adolf Hitler, a boss character in the game, had his moustache removed and was renamed "Staatmeister." Blood was replaced with sweat to make the game seem less violent (for SNES copies distributed in Germany, the enemy blood was turned green). Attack dogs were also replaced by giant mutant rats. Employees of id Software are quoted in The Official DOOM Player Guide about the reaction to Wolfenstein, claiming it to be ironic that it was morally acceptable to shoot people and rats, but not dogs.
