Horrified: Greek Monsters is a standalone game that features gameplay similar to 2019's Horrified. In this co-operative game, players become avatars of the Greek gods and must work together to re-capture these monsters.

To do that, they must first uncover the monsters' lairs. Medusa, Cerberus, Chimera, and Minotaur are hidden in locations that must be discovered: the Statue Garden, Underworld Door, Chimera's Cave, and Labyrinth. Similar to the myths that inspired the game, uncovering the lairs comes with a cost: Players must discard three color items before the lair token can be flipped over to reveal which monster's hideout they've discovered.

Horrified: Greek Monsters includes six monsters, each with unique abilities, and the more monsters in the game, the harder the challenge, with players needing to use their unique powers to figure out how to defeat each monster.
