About This Game

Happy Nuclear is an evidence-based investigation game where players act as detectives to prevent a disaster. They analyze interconnected case information on an investigation board, primarily using old CCTV and access logs. Cases link together at the end, and each replay introduces changes.

Detailed Description

Happy Nuclear

Happy Nuclear is a challenging puzzle investigation game that tests your thinking skills. Players take on the role of a detective who becomes involved with a terrorist organization planning to destroy the world with nuclear bombs. You must use logic and problem-solving skills to investigate and stop this organization before it's too late.
