Monster Pack – Cthulhu includes a new monster — Cthulhu, in case you couldn't guess — as well as eight evolution cards to use with King of Tokyo. You can also play with the cultist tiles, giving players a bonus effect once they obtain it! You also have eight evolution cards, fifteen cultist tokens (which are also Temple of Cthulhu), for King of New York. You now have new units and buidlings to fight for! Defeating a Cultist let's you obtian the tile and use it once to gain either 1 Life, 1 Energy or 1 extra Roll! Part of the King of Tokyo series.
