Story
After her devastating defeat by the Battletoads on Ragnarok's world, the humiliated Dark Queen has fled to the far reaches of the universe. Months have passed ... and the Queen's threat of revenge is but a distant memory for Professor T. Bird and the Battletoads - Zitz, Rash and Pimple. But when a mysterious energy beam from outer space wipes out Earth's military might and a city-sized spaceship named Colossus bursts out of the moon, the Professor knows it must be the Dark Queen attempting her latest plan to rule the galaxy. He's right, of course, but what he doesn't know is that this time the shady lady is taking no chances and has teamed up with the equally shady Shadow Boss! This means that the Battletoads not only have to fight the Queen and her henchmen General Slaughter, Big Blag and Robo Manus, but also Abobo and Roper, the Shadow Boss's henchmen! So here's the deal, Toads: the Dark Queen has got herself some serious support and is now coming to take over your Earth - what are you going to do about it? First of all, you're going to even the playing field! The awesome twins Billy and Jimmy Lee, also known as the Double Dragon, are keen to get involved, especially as the Shadow Boss is their worst enemy!
