Due to the theme of the game, it was subject to some censorship. Nintendo itself ordered all depictions of red blood and gore, be removed or changed to green ooze. Censorship committees at several European Nations, i.e. United Kingdom and Germany had the game renamed to 'Zombies' and ordered other changes, including making the chainsaw-wielding lunatics were replaced with lumberjacks with axes.
