Devil Crusade is a defense game in which you must protect a cat from hordes of demons! Move into enemies to strike them with your sword and prevent them from reaching the cat. You can also summon defenses with the orbs that circle around your character. Build light pillars that will attack enemies, place soul webs to slow down enemies, and summon priests to divert your enemies' attention away from the cat. Kill enemies to gain experience points, which are needed to upgrade your skills and defenses.
