It is located in The Underground section of the amusement park on a plot of land formerly occupied by the Psyclone (1991–2007), Shockwave (1986–1988) and Sarajevo Bobsleds (1984–1986).

[1] Six Flags spent approximately $1 million on the ride's theme surrounding the film, most of which was placed in the line queue area.

[2] The theme's storyline focused on trainees in a post-apocalyptic setting getting trapped by attacking machines at the amusement park, and the coaster serves as transportation to a safe house location.

[3] The onboard audio stopped working in early 2010 and was not repaired or replaced, although the rest of the ride's special effects remained intact.

[1][4] In late 2010 following a post-bankruptcy restructuring, Six Flags announced that it would be moving away from intellectual property licensing agreements, aside from those involving DC Comics, Hanna-Barbera and Looney Tunes.

[citation needed] The initiative involved rebranding Terminator Salvation: The Ride to a more generic theme as a cost-saving measure.

[1] Terminator animatronics and themes were removed from the queue, the ride received new signage, and new video was created for the preshow room.

[1] In 2015, Six Flags announced that Apocalypse would be temporarily renamed Shadows of Evil: The Ride as part of Activision's partnership to support the upcoming release of the highly anticipated Call of Duty: Black Ops III on November 6.

[7] Following an announcement in 2018 revealing a new roller coaster, West Coast Racers, Magic Mountain closed Apocalypse and the area it resides in.

On busier days, there will be an employee that controls the merge and only lets so many people beyond this point at a time, who then pass under the track again and into another holding area, just outside the pre-show building.
