It borrows the title from the 1979 thriller about a nuclear plant incident to set up an action-and-reflexes game where you have to keep the situation from spiraling out of control, within the usual mold of "high-concept" cartridges several low-budget publishers released for the 2600 in the early '80s. The connection to the film is more marketing than developed plot.
It's one of those titles remembered today more for the oddity of its premise — turning a real-world nuclear disaster into an excuse for a console game — than for its gameplay itself.
