Arc System Works, developers Drecom and SuperNiche have announced that “Speedrun-training simulation RPG” Demons’ Night Fever will launch for PlayStation 5, Switch, and Steam later in 2026.

 

Kill friends and foes alike! The more you die, the stronger you get in this ruthless speedrun-training simulation RPG. While built on classic grid-based tactical combat, Demons’ Night Fever shatters conventions with its dark comedy “Servant Overwork Mechanic,” forcing you to mercilessly sacrifice your own allies to win. The more misdeeds you commit, the more vicious your army becomes, and the greater your advantage in battle! Regain the lost power of the Devil, Giga Super Death, who was transformed into a baby, and crush the false god wearing a mask of justice!”
