Super Turbo Demon Busters! is a roguelike action-adventure game developed by HeroCraft, released in 2017 for PC. Players command a squad of space marines and mercenaries stranded on a hostile alien world teeming with monsters, viruses, nuclear hazards, and other lethal threats. The objective is survival and escape, with gameplay emphasizing fast, punishing encounters that combine running from environmental dangers with direct combat against enemies. Each level is procedurally generated, ensuring no two runs play out identically. The game offers a roster of multiple playable heroes alongside a wide variety of weapons, providing considerable build variety across attempts. Tonal influences from classic science fiction and horror properties such as DOOM and Alien are evident throughout, and the game incorporates a streak of ironic humor alongside its intense action. The overall experience prioritizes speed, replayability, and unpredictability.
