You play as Angelica Amadeus, a gun-wielding nun fighting demons in a fast-paced first-person shooter. The action takes place across seven surreal stages themed around the seven deadly sins, where gravity can shift your orientation as you move.
In the main mode, defeat as many demons as possible before the timer expires. Break scattered hourglasses to add time, and kill quickly to build combos and raise your score; high combos can trigger Holy Time, which strengthens your weapons and awards bonus points. Weapons have no ammunition to manage.
Storming Hell is joined by Time Attack, which challenges you to defeat a set number of demons quickly, and Survival, where you last as long as possible. Earn scores and ratings to unlock stages and weapons, then replay levels to pursue higher scores.
Players who enjoy the game often praise its fast, satisfying demon-slaying and combo scoring, along with its unusual gravity-shifting arenas, weapon selection, music, and memorable nun protagonist. Some find the gravity disorienting, and several describe the experience as short or repetitive, so the distinctive movement and compact arcade loop do not work for everyone.

Guns and Nuns is an old school FPS where you play as the nun Angelica Amadeus, storming hell for fun with two golden desert 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.
