Entering Dr. Bruce Banner's lab, guests learn that Banner is conducting special gamma-ray accelerator tests. They climb inside their vehicle and realize something has gone terribly wrong. Shooting out of the emerald Gamma Force Accelerator with the same thrust as a U.S. Air Force F-16 fighter attack jet- they know they are in for the thrill ride of their lives. First, the roller coaster blasts riders from zero to 40 mph in two seconds utilizing a specially designed booster thrust. Immediately following is a heartline inversion, 100 feet from the ground, during which guests go weightless. In two minutes and 15 seconds, the 32 passengers in the vehicle experience seven roll-overs and plunge into two deep subterranean enclosures.
