A Secret Revealed is a non-canon video that can be unlocked in God of War, specifically by beating the game on Spartan Mode. It shows the origin of Kratos, a child born out of wedlock in a small village. Shunned by their people due to wild rumors, Kratos and his mother, Callisto, fled to Sparta to start a new life. Kratos eventually became captain of the Spartan army, and left his mother behind.
