A thin membrane between two parallel worlds often began to erupt, and from there all evil spirits climbed. They urgently need fresh meat and our world - this is Klondike for demons and devils. Five years ago, evil monsters managed to break through and do a lot of trouble on Earth. People managed to mobilize and pacify the people from the underworld a little, but an even greater threat awaited them. The extremely embittered demon Zoltan burst out of Hell. Even there, he was imprisoned and accumulated a lot of anger. He longs to destroy and burn everything, and he has many supporters. You have to fight with them in Cemetery Warrior IV, as well as their leader.
