Guns and Nuns is an old school FPS where you play as the nun Angelica Amadeus, storming hell for fun with two golden Storming Eagles, destroying demons with the power of faith and hot lead through strange stages with bizarre gravity fields.

Your goal is to kill as many demons as possible before the timer runs out. You can extend the timer by breaking hourglasses scattered throughout each stage.

Killing demons quickly starts a combo chain: the higher the combo, the higher the score. Killing demons quickly enough makes the nun enter in "Holy Time"mode, Making her a psychopath, her guns stronger and allowing you gain bonus points during that state.
