The Tale of Bistun is an action-adventure game with an isometric camera view, inspired by the 12th century tragic poem "Khosrow and Shirin". You will play the role of a stone carver who wakes up on Mount Bistun, remembering nothing up to this point. The insidious infection has spread, giving rise to many dangerous enemies. You must battle mythical enemies and travel between the real world and an ethereal place of forgotten memories to uncover the secret of your past.
