The objective remains to be the first player to reach Level 10 by defeating monsters and collecting treasures. This expansion adds variety to the monsters you face, the items you find, and the curses that may befall you.
Players will continue to kick open doors, fight monsters, collect treasure, and backstab their friends, now with an expanded array of Cthulhu-themed challenges and rewards.
5. New Mechanics and Cards
This expansion introduces several new card types and mechanics to enrich your gameplay:
- More Madness: Encounter new curses, including "Phobia curses," which introduce unique challenges and interactions. For example, a phobia of being alone might force a player to seek help in combat, while a phobia of people might prevent them from accepting or offering assistance.
- More Monsters: Face Goomi's interpretations of classic Mythos creatures such as Great Cthulhoo, Dagoon, Narly, Tindaloo, Ygo, 'Zathoth, Nightgaunts, Ghouls, and Deepoines. These monsters come with new combat ratings and "Bad Stuff" effects.
- More Things That Put The Hurt On Monsters: Discover new weapons and items to aid you in your battles, including the Roman Candle, the giant Hypodermic Needle, and even a Can Opener. These items provide various bonuses and abilities.
