Crisol: Theater of Idols is a survival horror adventure from Vermila Studios, set in Hispania, a twisted version of Spain. Players control Gabriel, a soldier on a divine mission for the Sun God, tasked with exploring the cursed island of Tormentosa. The gameplay involves battling horrifying enemies and solving puzzles while uncovering the island's dark secrets and folklore.

A core mechanic requires players to use their own blood as ammunition, creating a risk-reward system where each shot drains health. Gabriel can upgrade his blood-based powers and weapons found throughout Tormentosa, improving combat effectiveness and survivability. The game blends historical events, folklore, and religious themes into its narrative, pitting players against supernatural threats.
