The Pictorians have arrived from deep in space. They also have dangly glow-balls on their heads, which is kinda cool, but still. The freaky aliens are using use their crazy rainbow-beam-thingy to paint everything on Earth the same color - white! If the Pictorians are to be stopped, the Allied guys and the Axis boys - plus some new characters, too - must set aside their differences, unite against their common foe, and hopefully get together for a sweaty workout to make sure they're super-ready to save the world!
