BlackThorne Keep is a narrative driven action RPG set in a low fantasy world much like western Europe and colonial Americas by the 1500s - with its own twist. The main story follows Thommas BlackThorne, the last heir of an once noble family as he struggles to live up to his family legacy: a torn up castle and fading family name.

Within its core, BlackThorne Keep brings to the table an engaging combat system based on Directional Melee fighting, cinematic combat maneuvers and strategic character development choices. Beyond combat, the game brings a plethora of story decisions and consequences through the Karma system - a mechanic which tracks the players actions and feeds it back into the story events - and the Interaction and Exploration Scenes mechanics, which bring a new dimension to puzzles and NPC interactions throughout the game.
