The existing Mr Freeze roller coasters at Six Flags Over Texas and Six Flags St Louis will both be updated for the 2012 season, the parks have confirmed.
The coasters will be renamed as Mr Freeze Reverse Blast, with the direction of the rides' trains being reversed. This means that riders will be launched from 0 to 70 miles per hour in a backwards direction, traversing a series of inversions and turns before returning to the station in the opposite direction.
The preview video below shows the planned experience that Mr Freeze Reverse Blast will offer:
Both versions of Mr Freeze were manufacture by Premier Rides, and are mirror images of each other. Following the initial launch, the coasters' trains race through a 190-feet tunnel before climbing a 150-feet-tall top hat inversion. After travelling around an overbanked turn, the trains climbs up a vertical spike, before plummeting back around the remainder of the course in reverse.
Six Flags' Chief Operating Officer Al Weber said of the changes: "Reversing the direction of the trains on two of our most popular coasters is a fun twist on the ride experience. Mr Freeze Reverse Blast demonstrates Six Flags' commitment to continually push the envelope and deliver new and innovative thrills to our guests."
