This game is known as a horror game is even similar to residents massacre. So how could a missing worker gone? So firstly when he got home from work he checked on his Tv that the reports of the factory the 1 worker was missing cause of the leak it was a acidand there was chemical spreading all over the factory and 1 day police reports that the gas leak was removed and they suddenly suspected a noise from the factory they decided to check the worker became a monster, and then they realised that it was a worker that he is missing from the factory. In the next day, the news reported that people should not go outside must stay indoors, the gas leak was back and spreading all over the city.
