About The Monster Within

ABOUT THIS GAME
Monsters roam the streets of the city, including you! Fight off sinister creatures while stopping yourself from turning into one too in this deck building card game. Craft a unique deck each round from Day cards, Night cards, and Monster cards. Do you try to stay above board and beat your opponents through clever investigation and tactics, use the seeder underbelly of the city to your advantage, or embrace your burgeoning evil instincts? Or maybe mix a bit of all three! Pick one of six different classic monsters to play as. Unlock new cards and characters as you play, unlocking more and more playstyles and strategies. Themed after 1950's horror comics, build the story of your battle with the cards you play.




In classic deck building fashion, buy cards to use to damage your opponent, protect yourself, or just buy even better cards in the future. Over two hundred cards to play with and unlock.


Take your pick of monsters each with their own cards and strategy. Feed on your foes blood as the Vampire, embrace the night as a the Wraith, make your opponents green with envy as the Plant, crush them with sheer bulk as the Blob, and more! Each monster also has two other monsters it can pair up with to make a mashup monster. Vampire + Wraith? Lich! Cultist + Warlock? Mummy! Mad Scientist + Blob? Play the game and find out!


As you loose health, you become more and more monstrous and the cards you can buy change. Keep your health high to stay in the Day, or intentionally let it slip to gain powerful Monster cards. Just don't let yourself fully lose control to the monster within!


Fangs, Scaly Skin, Mysterious Secretions, take your pick of Afflictions each round to power up your character and find new strategies to win. What's a little inhumanity when it comes with such power?


Use the Blood system to make the game more difficult the more you play it. The harder it is, the faster you'll unlock more content.

The Monster Within is fully playable and out of early access! All ten monsters, all ten mashups, almost 50 afflictions, and almost 400 cards are in the game for your deckbuilding pleasure!
