Disaster! Falling into the Purgatory Principle

(Principles of purgatory in horror games, killing monsters in the desert forest to survive.) (No heroine, pure survival, fatal game, game program, forced choice in disaster, infinite flow, various strange creatures appear, monsters must be hunted to obtain upgrades.) Taking the subway to work, I thought it would be another boring commute. After waking up from the subway disaster, I was trapped in a game of purgatory principles with dozens of people. After one operation, I thought they were all going to die, but in the end I just participated in the game trial and killed the monsters set by the game program. Before returning to the real world, they must overcome difficulties, survive, and get rid of the constraints of the rules of the game. Only then can everyone stop wandering in the game world.
