En raison de la terrible pollution de l`air et du désastre financier ayant frappé Tokyo, le Japon a décidé de changer de capitale. Tokyo, rebaptisé Old Tokyo, est aujourd`hui devenu le terrain de bataille où s`est implanté un nouveau genre de divertissement appelé Combat en Arène. Les spectateurs, placés sur de gigantesques tribunes aériennes, regardent les Scoobees combattre jusqu`à la mort.

The year is 2025. The Japanese government, in order to cope with the massive air pollution and endless economic loss of Tokyo, transfers the capital to "Neo Tokyo", a dome city built on the Tokyo Harbor. A few years later, abandoned "Old Tokyo" becomes the battleground for "Rumbling". In Rumbling, the contenders face each other while riding highly mobile armored land vehicles called "Scoobees", and receive fortune and fame by destroying others. It's now the year 2031, the Rumbling is the biggest hit the entertainment business ever had! Now is the time for YOU to join the Rumbling. To proclaim you are the master of the battle!
