Demons' Night Fever Gameplay Trailer showcases the strategy RPG gameplay

Arc System Works has published a new Gameplay Trailer for Demons' Night Fever at the Arc Showcase 2026. This trailer lets you check out a sneak peek of the new tactical RPG made by SuperNiche's Sohei Niikawa of Disgaea fame.

Even though a Japanese version of the trailer is also available, it still uses English voiceovers. The Steam page has indicated that Demons' Night Fever will support not only English voiceovers but also Japanese, with additional subtitle options in French, Korean, and Chinese (Traditional & Simplified).

You can find the official English gameplay trailer for Demons' Night Fever right below. The game is slated for a worldwide release on Nintendo Switch, PlayStation 5, and PC via Steam 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!"

Arc System Works has dropped an all-new gameplay introduction trailer today. Demons' Night Fever is scheduled to launch later in 2026. Stay tuned for more updates!
