THE REAKTOR STORY

One day, a bored engineer at the Chernobyl nuclear power plant modified the SKALA control program with a score function so it would be more fun to play. He began making larger and larger reactions, until one day he messed up and caused a meltdown.

But he was addicted.

Years later, he sneaked back into the rubble, stole the modified control code, and published it as an internationally acclaimed video game called REAKTOR.
