> Chernobyl is a realistic nuclear power plant simulator by Paul Norman for CBM64 and 128. The player controls the various systems of a nuclear reactor’s control room, and is faced with a multitude of dangerous situations.


Produced by Cosmi back at 1988  it’s a perfect simulation on the management of a nuclear power plant and high crisis situations that can turn in a death clock countdown.
