Shockwave @ Great America Description: With its harrowing 155-foot drop into 3 lofty vertical loops, a boomerang, and two corkscrews at speeds up to 65 mph, Shockwave was the first of Six Flags' three mega-loopers. Unfortunately, this landmark coaster is now closed. Its parts lay in neat rows in one of Great America's lots waiting to be purchased by another park. This recreation includes a very highly detailed station complex. RCT/LL/Gold and RCT2 tracks included. Last Updated: 07-Sep-2004
