Battletoads & Double Dragon was developed by Rare and published by Tradewest in 1993, a crossover that brought together two of the best-known beat ’em up names on the NES. The Dark Queen has teamed up with the Shadow Boss, leader of the Shadow Warriors, and their giant spaceship, the Colossus, is threatening Earth. Rash, Zitz and Pimple join forces with Billy and Jimmy Lee to stop them, and the player can pick any of the five heroes, each with signature moves drawn from their own series. The toads still smash enemies with exaggerated morphing attacks, while the Lee brothers rely on martial-arts combos. Stages range from brawls on the hull of the Colossus to a speeder-bike chase and a descent into a fortress, mixing straight fighting with the vehicle sections Battletoads was known for. Two players can team up, and the difficulty is more forgiving than the original Battletoads, which made it more approachable for a wider audience.
