Poltergeist

Poltergeist is a steel roller coaster located at Six Flags Fiesta Texas in San Antonio, Texas. It has been open since 1999 and received a fresh coat of paint in 2009. Although the ride is considered to be manufactured by Premier Rides, the track itself was fabricated by Dynamic Structures and Intermountain Lift, Inc.
After boarding Poltergeist, riders are launched through a narrow launch tunnel into a "spaghetti bowl" of track which contains a cobra roll, a sidewinder, and many twists and turns. This coaster doesn't have a mid-course brake run like Flight of Fear has at Kings Island and Kings Dominion, or rings like Joker's Jinx at Six Flags America. After that riders spiral downward and to the left and after more twists and turns they pass through a corkscrew before arriving at the ride's final brake run.
