UNIT9 is set to release a new free-to-play card battling RPG called Decromancer, which is scheduled to bring a quest-filled single player campaign to the App Store on November 6. Players must use strategy when recruiting an army and dealing with foes on the battlefield. Being victorious leads to upgrading their army and magic spells, of course. Check out the trailer below to get a closer look at the world of Decromancer.
