Helix is the first roller coaster in the world that has a 1-on-1 replica virtual reality experience. This experience is created by ArchiVision, a Dutch 3D studio. During the first two weeks after the premiere visitors could experience the virtual reality replica next to the roller coaster's entrance. {{citation needed|date=July 2014}}

The roller coaster's station building is located where the 3D cinema Maxxima used to be, by the foot of the tower AtmosFear. The {{convert|1,381|m|ft|adj=mid|-long}} track follows the hillside in a custom-made track design. The elements during the ride include two corkscrews, a pretzel knot, a top hat, a zero-g roll, and a rare Norwegian loop.

The estimated cost for the project is about 239,000,000 Swedish kronor.
