On 26 December 1995, Lethal Weapon – The Ride officially opened to the public. It was the first Suspended Looping Coaster to feature an extended layout with a helix before the brake run. This helix was referred to as a "bayern kurve" by Vekoma. Riders would originally join in the queue by entering an area of the theme park made up like Chinatown, complete with a variety of facades such as "Lee's Martial Arts School" and various restaurants and sundry shops. The queue started outdoors, before moving into a movie-theatre like hall where riders watched sequences of the film while waiting to ride. Before finally riding, riders would progress into an area made up like an auto yard, with cars piled up atop each other and graffiti all over the walls, with the sound of barking Dobermans as well as a seemingly abandoned Shell auto station. After hearing an audio presentation and removing any loose items, riders are strapped in and the ride is dispatched. In the mid-2000s the ride's queue was altered to bypass most of this theming except for the autoyard. The revised queue was located in the pathway between the original Lethal Weapon – The Ride entrance and Superman Escape. This resulted in a considerably shorter queue which had originally made up just the last portion. This was done due to the popularity of the ride dipping as both it, and the film franchise aged.
Arkham Asylum (2012–present)
In September 2011, parts of new trains were spotted in a maintenance area of the ride. The new trains were designed by Kumbak, the company responsible for 2009 installation of new trains on Sea World's Sea Viperroller coaster. At around the same time, the ride's entrance was moved to a new location in the pathway between the original Lethal Weapon – The Ride entrance and Superman Escape. On 27 January 2012, Lethal Weapon – The Ride closed for an extended maintenance period until 1 April. On 30 January 2012, Warner Bros. Movie World announced via Facebook that a new experience would replace Lethal Weapon – The Ride in time for Easter. Images released hinted at the ride being rethemed to Arkham Asylum with the addition of new coaster trains. On 10 March 2012, Warner Bros. Movie World announced via their Facebook page that the ride would be rethemed into Arkham Asylum featuring a new train with on-board audio and modified restraints. On 7 April 2012, Arkham Asylum officially opened to the public. Theming for the relaunched attraction was developed by Sculpt Studios. Riders join the queue outside the asylum, where the Joker has sprayed graffiti around the area. Entering the asylum, they find a tv smashed onto a guard, showing news reports on all of the rogues of Batman taking over Arkham. The guests then walk down the cell block viewing the files of selected Batman villains including Poison Ivy and Two-Face.
Ride
The train climbs the lift hill, before dropping down a steep, curved drop to the right. The train then enters the roll over, followed by a hill with a banked turn to the left. At the bottom of the hill comes a sidewinder, followed by a 270-degree turn to the right. Next comes two inline twists. Upon exiting this element riders experience a download 180-degree turn to the right. Unlike most Vekoma Suspended Looping Roller Coasters, Arkham Asylum features an additional helix just before the brake run. This element was referred to as the "bayern kurve" by Vekoma and was the first to be installed in any Suspended Looping Roller Coaster. After the ride, guests proceed past an observation deck for the ride and past the ride's former gift shop where they arrive back in Chinatown.
Trains
When the ride was known as Lethal Weapon – The Ride, it had 2 Vekoma trains with 10 cars per train. Riders were arranged 2 across in a single row for a total of 20 riders per train. The two trains are very similar in colour although one features some red elements while the other features blue elements. As part of the Arkham Asylum retheme, the ride features new trains with modified restraints which increase upper body movement during the ride. The trains were manufactured by Kumbak and were originally set to feature on-board audio.
