Darktower Dive
Darktower Dive is a themed Gerstlauer Eurofighter featuring many inversions. Its elements include (in ride order): enclosed vertical lift, beyond vertical drop, vertical loop, immelmann, zero-g roll, enclosed vertical lift, enclosed beyond vertical drop, cobra roll, norwegian loop (dive loop followed by immelmann). This makes for a total of 7 inversions (although the in-game counter says 9 presumably because it’s counting beyond vertical drops).
Note that the blueprint also includes a few shops and a bathroom as well as many trees. Since the original coaster was on a hill, some of the scenery may require reworking if you place it in your park to work with surrounding terrain. Also, I’m not sure why it says the results of testing are outdated since I had tested it prior to opening and have not made any changes since then.
Approximate Cost: ~$38,779.40
