Magnum XL-200, colloquially known as simply Magnum, is a steel roller coaster built by Arrow Dynamics at Cedar Point in Sandusky, Ohio. When it opened in 1989, it was the tallest, fastest, and steepest complete-circuit roller coaster in the world as well as the first hypercoaster – a roller coaster that exceeds in height. Some have credited Magnum with starting a period in the industry known as the "roller coaster wars", in which amusement parks competed with one another at a rapid pace to build the next tallest and fastest roller coaster. More than 40 million people had ridden Magnum as of 2009.
