Mr. Freeze: Reverse Blast is a steel launched shuttle roller coaster located at Six Flags St. Louis in Eureka, Missouri, USA. It is a prototype Shuttle Catapult Coaster built by Premier Rides. There is a mirror image of the ride located at Six Flags Over Texas.


Mr. Freeze was originally going to open in 1997, along with the release of Batman & Robin, but the ride suffered launch system problems. For this, the ride's opening was delayed to 1998.[1] It eventually opened on April 10, 1998.[2]

When the ride first opened, it had over-the-shoulder restraints. Due to a rough ride experience, they were later replaced with individual ratcheting lap bars for the 2002 season.

In 2012, the park announced that Mr. Freeze would run backwards.[3]



Ride experience

Riders begin boarding on a train backwards. The ride features a switchback, allowing for two trains to run. The ride launches guests from 0-70 mph in 3.8 seconds using an LIM Launch. Following that, riders experience a 150 foot tall inverted top hat. Immediately, riders will go through a 113 foot tall 140 degree over-banked curve. They will then go up a 218 foot tall vertical spike. To help the ride gain enough speed to complete the course forwards and backwards, there is an LIM boost that pulls the train higher on the spike, and then thrust it down. The riders then traverse the course again forwards.


2 trains with 5 cars per train. In each car, riders are arranged 2 across in 2 rows, for a total of 20 riders per train.
