About the game
Castle of Blackwater is a multiplayer social deduction game where 10 players navigate a magical 2D castle while completing tasks and uncovering hidden allegiances. Players are assigned to three different factions, each equipped with unique abilities that support their role in the game. While alive, participants use various tools to gather information and identify threats, while eliminated players can influence the outcome by collecting souls to purchase power-ups for their team. Through alliance-building, deception, and strategic ability usage, players work to ensure their faction's survival and ultimate control of the castle.
