About Demons' Night Fever
Demons' Night Fever is a grid-based strategy RPG about restoring the power of Giga Super Death, a Devil transformed into a baby, and defeating a false god who wears a mask of justice. You lead an army through battles where you can sacrifice your own allies, the Peons, to gain an advantage.
Story
The game takes place on another Earth, different from our own. Giga Super Death, the most wicked Devil, is on the verge of killing God when he is suddenly turned into a helpless baby. He activates the resurrection program “DEMONS' NIGHT FEVER,” which he had been developing in case of such a crisis.
The ritual ensnares Killshiro Katanaka, a gloomy young man who despises the world. Their interests align, and the two form a pact: Giga Super Death and his new disciple Killshiro set out on a story of pure evil.
Sacrifice in battle
The Peon Exploitation System lets you sacrifice allied Peons during combat. You can use Kill Skills and detonate your own underlings to help secure victory. The more misdeeds you commit, the stronger your army becomes and the greater your advantage in battle.
Build your evil army
You earn Perverse Points through misdeeds and spend them to build your own army. With limited time, use Abductions and Pillaging to strengthen your characters to their limits.
A changing story
After you defeat each chapter's boss, the situation changes completely. The story lets you commit different kinds of misdeeds, including becoming a monster to defeat Super Rangers or a witch to crush Magical Girls.
