A new Christian (as in born again) video game where you get to kill unbelievers ie satanists, catholics, jews, Muslims, Buddhists, gays, and anyone who advocates the separation of church and state - especially moderate, mainstream Christians - you know, the usual crew. Alternatively you could play the antichrist's side.
While you're waiting for that game to be released you can play Rod Flander's Bible Blaster (click on rod's file)
