Luigi's Requiem is a community-created Mod built upon the 2001 Nintendo GameCube Adventure title, *Luigi's Mansion*. This modification shifts the core experience into a haunting nightmare, focusing on psychological tension and escape rather than standard ghost hunting. As an Adventure Mod, it reinterprets the familiar setting with a darker narrative, challenging players who enjoy seeing established worlds twisted into survival scenarios. The gameplay loop involves navigating this unsettling environment, leveraging the original game's mechanics to endure a desperate ordeal.
