Arc System Works America, Inc. has released Demons’ Night Fever across PlayStation 5, Nintendo Switch, and Steam platforms today, priced at $39.99. Demons’ Night Fever is an unconventional stat-raising strategy RPG based on the concept of “enjoying evil.”

Enjoy a dark and exhilarating strategic battle unlike anything you've experienced before, with features such as the Peon Exploitation System where you can blow up your own servants in battle, and the Perverse Points system, which allows you to freely train your characters in your hideout as you commit evil deeds and become stronger.

Arc System Works has also unveiled a new graphic showcasing syudou, the creator of the main theme song “Dropout,” celebrating Demons’ Night Fever’s release.

Produced by Sohei Niikawa, and developed by SuperNiche and Drecom, Demons’ Night Fever brings classic grid-based tactical combat that shatters conventions with its dark comedy "Peon Exploitation System," forcing players to mercilessly sacrifice their own allies (alongside killing enemies) in order to win. 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. Anticipating such a crisis, Giga Super Death 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.

Gameplay Details

• An Unconventional Strategic Battle! – Players are tasked with exhausting 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 setting completely transforms. Experience the full thrill of diverse misdeeds, such as being a monster to defeat Super Rangers, being a witch to crush Magical Girls, or others.
