International manual description[]
Often confused with a popular singing group from the 1960's, this level will separate the ultimate starfighters from the wimpy ones. It's packed with dozens of Bartanium Booby Traps, probably a starfighter's biggest single fear. Note: This level isn't included in the Practice Galaxy. To reach it. you must be one lucky son of a ray gun!
