Trials of the Demonic Seal

About this game

Trials of Demonic Seal is a top-down 3D action game set in a dark fantasy world. Play as a captured adventurer who must survive in a brutal environment by taking on demon ambushes and an array of twisted challenges. Escape...or die trying.

Choose a human captive—Only the strong survive!

Countless young women have been captured, each with her own personality and combat skills. Carefully choose your challenger, lest she be crushed by evil!

Randomized system—Take control!

The demonic power that binds you shall become your greatest asset. Defeat powerful foes and enhance your equipment to prepare for the final battle...with the lord of demons!

Formidable demons with distinct personalities!

Within the demon realm, each faction is led by its own unique leader. Prove yourself by taking on various trials to earn the right to face powerful fiends and foes.

Those who fail shall be mercilessly punished!

During your trials and tribulations, demonic runes will gradually erode the captive's will. Those who fail will face merciless punishment, be served as demonic sustenance, or even...as their sexual plaything.



Your demon overlords are watching. Will you reign victorious...or suffer a depraved defeat?
