Your mentor and brethren have been captured by the demon possessed Roman soldiers. It is your job to work you way through the catacombs of Rome to free them. Satan has a powerful hand in the Roman Empire and has powerful foes to block your every effort. From the prison, in which your mentor is kept, he sends a plea for help to you. According to Acts 26:18kj. Our Catechumen is sent to open their eyes (the Roman Soldiers), and to turn them from darkness to light, and from the power of Satan unto God, that they may receive forgiveness of sins. Prepare to save your mentor and battle the forces of evil in this epic journey, Catechumen.
