While I don't exactly want to spoil what creatures you will be facing, they will mostly be greek/mythical beasts. You know, Minotaur, Chimera, fierce beasts that will stop at nothing to eat you. 

Or mate with your corpse, but whatever.

Here's a link to Wikipedia:

While they will be kill-able, don't expect it to be a cake walk. These beasts were killed by men all the same, but if I were you, I would just run.
