Thrillseekers eager to try Perth's new roller-coaster can compete online for a seat on the $12 million ride's maiden journey.
After months of speculation, Adventure World has revealed the ride will be called Abyss, inspired by the ancient Druid guardians of the all-powerful Abyss.
Online game The Chosen Ones has been launched ahead of the roller-coaster's big reveal in early November.
The eight winners of that team-based treasure hunt will be the first on the roller-coaster at its launch.
The German-built ride has a 10-storey vertical lift, drops more than 30m and has G-force twists of up to 4.5.
An unnerving landscape with 30 guardians 3m tall, upturned trees with exposed roots and an intimidating arch welcoming patrons with a feeling of impending doom will complement the scream-worthy loops.
The 630m ride, which encompasses the entire roller- coaster area at Adventure World, promises to plunge the brave souls into a black hole of exhilaration.
Adventure World chief executive Mark Shaw said today's naming of the Abyss brought it a step closer.
"The name reflects what is going to be a white-knuckle ride filled with the trepidation of the unknown, the likes of which visitors to any theme park in Australia won't have experienced," Mr Shaw said.
"The theme is scary fun, sort of a mix of Harry Potter and Lord of the Rings scary, nothing grotesque."
Abyss is the park's biggest investment since it opened 30 years ago.
The ride will be one of the most advanced roller- coasters in Australia, with thrusts greater than those in a space shuttle launch.
Building began in May with engineers and technicians from German manufacturer Gerstlauer overseeing the project.The ride also has a dark ride section.
