Stomping Ground THUNDERDOME is a competition-style improv show where individual improvisers compete to win in the future dystopian arena of SG until only one improviser is left as the victor!

In a dystopian future, the totalitarian nation of Improvia is divided into 12 districts and the Capitol. Every month one representative, or Improviser, from each district is selected by lottery to participate in THUNDERDOME in the SG Arena.

Come watch as the Improvisers compete in a battery of games and scenes to be crowned the Champion of Improv! Hosted by John Gerhardt and Lynsey Hale and judged by the audience, this is one show where only the strongest (scenes) will survive!
