Viper was the third and final installation of seven-loop coasters that Arrow built for the Six Flags chain.  The other coasters are the Great American Scream Machine at Six Flags Great Adventure and Shockwave at Six Flags Great AmericaShockwave was scrapped in 2004, and Great American Scream Machine was torn down in 2010, so Viper is the last of the these seven-loopers still running.

The three coasters were very similar.  The inversions were nearly identical, but the transitions between the loops were slightly different.  Also, Viper was a just a few feet taller than the other two.  This gave Viper the title of world's tallest looping coaster when it opened.
