MAP31: Cybernation is the first secret map of Plutonia 2. It was designed by Alexander S. (Eternal), and uses the music track "Sinister" by Robert Prince. The intermission screen before this level states: "They lay in the stone houses of their court, preserved by spells for a glorious resurrection when the stars and the earth might once more be ready for them." This level can be accessed via a secret exit in Where Hate Runs Red (MAP15).
