Based on the "The Pilgrim's Progress" by John Bunyan, this story is an allegory of a Christian life, starting from the time a person learns of Jesus to the time when they die and reach The Celestial City (Heaven). In the game you take control of Christian as he journeys from his doomed hometown, The City of Destruction, and toward the Celestial City.
