Invertigo is an inverted shuttle roller coaster model developed and manufactured by Dutch company Vekoma.

Four roller coasters based on this model were built, with the first installation opening in 1997 as HangOver at Liseberg amusement park located in Sweden.

Invertigo's seat configuration is also a departure from its predecessor, in that riders sit back-to-back, resulting in all rows facing one another with the exception of the first and last.

During this time, the track received a new teal paint scheme, with the supports remaining in royal blue.

[15][16][17] An incident on May 3, 2014, resulted in a temporary closure when the coaster experienced a rollback that injured two riders – both were transported to the hospital.

[19][20][21] In 2011, Sommerland Syd's installation of Tornado closed with the ride currently being relocated to Bagatelle where it operates as Triops from June 30, 2012.

[8][22][23] On February 13, 2012, Kings Island posted a picture of Invertigo getting a new paint scheme on their Facebook page.

Once towed to the top, the train is quickly released sending riders through the ride in reverse before being caught by the first lift hill and returned to the loading station.
