A document has been found for the new Wanda theme park which is believed to open next year.
"Wanda is located in Hefei City, flip coaster theme park, we used two cars relative sliding, giving passengers the illusion of the two vehicles collided. The highest car segment by segment orbit flip flip flip body 90 °, vertical drop passengers are facing the ground. Features of the roller coaster is: two vehicles collided simulation, train tracks carrying flip 90 °, vertical drop.”
This picture proves that it will be a duelling tilt coaster, probably more than the really poor description of it.
