Fighting evil never felt so active. YOUR STORY A demonic revolution is spreading through our world, and God needs you—we all do. Celestial beings have strayed from their paths, and a purifying light is required to bring them back. That light is now within your iPhone, in a sacred union of technology and the supernatural. Embrace this destiny and embark on a pilgrimage that will test the limits of your mental and physical resilience. A divine test from God, or in some twisted way, from the Devil himself. Or could it be the reverse? ACTIVE ACTION MECHANICS Devil's Purge brings the extravagant action of 'FPS' or 'Hack and Slash' into the real world through augmented reality. Use your iPhone's camera to reveal grotesque demons that appear before you, and exorcise them with the piercing light from your device's flashlight. Active movement is key to being a successful demon hunter. You must physically dodge attacks coming your way and aim precisely at the heart of these macabre creatures. Delight in their bursts of celestial light that bring peace to their tormented souls ROGUELIKE Boost your divine power with blessings from the archangels Saint Michael, Gabriel, and Raphael, who offer hundreds of abilities to choose and combine. Create a powerful weapon in each session, exploring different playstyles against the demonic hordes. The King of all kings will also appear, granting mighty miracles to help restore the good name of the saints, now transformed into demonic forms. Survive wave after wave until you face the fallen angel: Satan.
