Enter the world of Lunatics and immortal hunters, with RUIN: Beast City, a stylish action game inspired by violent anime and 80s aesthetics. A demo for Steam Next Fest is now available.
12 FEBRUARY 2026 - Belgian solodev DascuMaru is thrilled to announce RUIN: Beast City, a new boss-rush action game that is sure to get your blood flowing.
Play as the lone assassin Adama, on his mission to track down a group of elusive immortals, the Lunatics cult. Slash and shoot your way through challenging boss fights against these mysterious foes, while uncovering a world-ending conspiracy and Adama’s own history with this hidden cult.
A demo is out now on Steam, giving players a first taste of this dark quest for revenge and retribution, with two boss fights to test your skill. The demo will participate in the upcoming Steam Next Fest, from 23 February to 2 March, and will remain available for download afterwards.
RUIN: Beast City is inspired by 80s anime, such as the works of Yoshiaki Kawajiri of Vampire Hunter D: Bloodlust and Ninja Scroll fame, as well as the intense and off-beat vibes of Suda51’s No More Heroes and Killer7.
