Launch your Defender Space Craft from it's docking bay and race to the Ion Field! There you will retrieve Ion Generators, one at a time, and transport them back to your docking bay to install in your circuit board. Watch out for aliens and don't crash, otherwise you will have to return to a repair station or your docking bay before continuing your mission. The first player to complete a circuit board by installing three different colored Ion Generators is the victor in this space-themed spin-and-move children's game. —user summary
