"Find and break the mythical Unicorn"
The player must complete and attain rank 5 in the "Undead Hunter" challenge before finding the Unicorn. Players can find the unicorn around Diez Coronas and Torquemada.
Unlike the other mythical creatures in Undead Nightmare, the player won't get a warning that there is a mythical creature in the area. From a distance it looks similar to an Hungarian Half-bred but getting up close the player will not only notice the Unicorn's legendary horn on its forehead, but will also see a cloud of butterflies all around it and when it gallops, there's a distinct rainbow-colored trail.
