Opened in May 2009, Apocalypse was originally known as Terminator Salvation: The Ride, and was designed to tie in with the Christian Bale movie. The theme was dropped in January 2011 as part of an initiative by Six Flags to drop a number of expensive licensing deals.
A new pre-show will replace the existing one when the ride transitioned to become Apocalypse. The updated storyline sees riders joining survivors of a global war in a bunker, before "escaping" via the coaster. The existing smoke and fog effects on the attraction were retained, although animatronic Terminator robots were removed from the queue line.
Apocalypse is a wooden rollercoaster, and features unusually heavy theming for a Six Flags attraction. Its circuit boasts a 100-foot lift hill, a 53-degree first drop and five hills.
When the ride opened, it featured an on-board sound system (a world's first for a wooden coaster), but this broke down in 2010 and has never been restored.
