You, as the bravest superhero, will have to take on the role of the Chernobyl nuclear power plant operator and control all the processes in order to put the station into a safe operation mode. • This hardcore game consists of 12 levels. • Each level becomes available after completing the previous objectives. • At first, you will go through the training and learn how to manage a nuclear power plant. • You will have access to various improvements and bonuses that will help to optimize the control process of our nuclear reactor.
