Justice League: Battle for Metropolis

Justice League: Battle for Metropolis is an Interactive Dark Ride located at two Six Flags theme parks in the United States. Designed by Sally Corporation, an American ride manufacturer. Since 2014, Six Flags has installed the dark ride at two of their parks and is currently building two more at two other parks.

History
In October 2011, the chairman and CEO of Sally Corporation, John Wood, stated they had started developing their biggest project, something which they believe would be "the top of the industry". The project was later announced to be Justice League: Alien Invasion 3D at Warner Bros. Movie World on the Gold Coast, Australia. Following the launch of the ride in September 2012, Sally Corporation expressed interest in transferring the concept to other parks around the world including those in the United States. In the United States, the Justice League brand, along with other DC Comics properties, are licensed by Six Flags.

On August 28, 2014, Six Flags officially announced Justice League: Battle for Metropolis would be added in 2015 to Six Flags Over Texas and Six Flags St. Louis. In Six Flags Over Texas the ride would replace the Adventure Theater, while the Six Flags St. Louis attraction Scooby-Doo! Ghostblasters: The Mystery of the Scary Swamp ride would be replaced. Noticeable differences between Justice League: Alien Invasion 3D and Justice League: Battle for Metropolis include a motion-based ride system by Oceaneering International and the involvement of additional DC Comics villains including Lex Luthor and The Joker.

On September 2, 2014, in an interview with Sally Corporation CEO John Wood, new details about the attraction were released. Six Flags Over Texas received ten ride vehicles, while Six Flags St. Louis received seven. The ride features two final chase scenes, as well as eight Digital 3D Screens inside the ride that are as large as 30 feet wide.

On September 3, 2015, Six Flags announced Justice League: Battle for Metropolis would be added to Six Flags Great America and Six Flags México in 2016.
