Arc System Works and Drecom Co. have announced that Demons’ Night Fever is in development for Nintendo Switch.
Pitched as a “ruthless speedrun-training simulation RPG,” the game has been built around classic grid-based tactical combat, but as an experience “shatters conventions” with its dark comedy Servant Overwork Mechanic.
This will force you to mercilessly sacrifice your own allies to win, as the more misdeeds you commit, the more vicious your army will become and the greater your advantage will be in battle.
“This is a story of another Earth, different from the one we live on. Giga Super Death, the most wicked Devil of all, was just one step away from killing God… when suddenly, he was transformed into a helpless baby,” the publisher writes in outlining the game’s premise.
“Anticipating such a crisis, he had been working through the night to develop the
Demons’ Night Fever resurrection program – and finally, it was time to activate it.
Was it a prank of fate, or inevitable destiny? The one ensnared in this suspicious ritual was Killshiro Katanaka, a gloomy young man who despises the world. Due to their aligned interests, a bizarre pact was formed. This is the story of pure EVIL, starring the Devil himself and his newfound disciple, Killshiro.”
The publisher has outlined the game’s key features, which include:
- Kill, kill, kill both enemies and allies! An unconventional strategic battle! Exhaust all forms of evil using the Peon Exploitation System, which sacrifices your allied Peons during battle! Brutal tactics such as Kill Skills and Sacrifices that detonate your underlings with your own hands are the shortest route to victory.
- The more you sin, the stronger you become! Master your base to unleash pure chaos. Pour in the Perverse Points earned through misdeeds to build your own ultimate evil army! Within the limited time, make full use of suspicious Abductions and Pillaging to strengthen your characters to their absolute limits.
- A world that warps with every chapter! Dive into a story where no act of evil is off-limits! Every time you defeat a chapter’s boss, the game’s situation completely transforms! Experience the full thrill of diverse misdeeds, such as be a monster to defeat Super Rangers, be a witch to crush Magical Girls, or others!
Demons’ Night Fever will be released digitally on the Nintendo eShop for Nintendo Switch worldwide in 2026.
