Administrator of the Abyss

The moment the subway door closed, everyone's mobile phones lit up with a scarlet prompt: "Welcome to the Abyss Platform Game, there are currently 100 surviving players." A tunnel of flesh and blood crawled outside the window, and the passengers beside him were suddenly swallowed by shadows. Only an abnormal message appeared on my screen: "Administrator permissions have been activated" - In this endless loop of horror sites, others are struggling to survive, but I can get a glimpse of the background data of the death rules.
