The object of the game is to shoot bibles at heathens and convert them to Christianity. To win the player must turn 10 heathens into Christians in a limited amount of time. 125 points are awarded for a successful shot, and 25 points are deducted after a miss. A partial conversion will make the heathen a Unitarian.
Behind the laughter Edit
- It is based on the unlicensed NES game Spiritual Warfare, where, like Billy Graham's Bible Blaster, the player is encouraged to "convert the heathens" by shooting them.
- On the official Simpsons website it is featured as a minigame on Rod's character biography.
