AR: How often are there games where nuns are the main character, let alone where they are shooting everything in sight? Nun Attack is that game. The demo video below shows a pretty good representation of what the game is like. It all starts with one nun with two handguns. She’s kicking butt against evil from a different realm. The skeletons come out of a portal and try to attack the world, but this killer nun will have none of it.
