[3] It was announced on September 16, 2013, that the series has been renewed for an eight-episode second season with Mark McGrath replacing Steve-O as host.

The winner for each round is picked by the live studio audience via popular vote and is automatically advanced into the Killer Karaoke Final Showdown.

Six contestants take turns singing portions of one song, occasionally being given electric shocks or sprayed with water from their microphones to distract them.

The three preliminary round winners battle against each other for up to $10,000 in prize money while singing on the "World's Largest Turntable," a spinning disk approximately eight feet in diameter and decorated with a radiation warning symbol.

The two finalists wear suits with $10,000 cash attached to them, and must go through three obstacles designed to cause the money to fall off while singing the same song.

Once they complete the obstacles, they return to center stage as clear boxes are lowered onto their heads and filled with one of their worst fears.

The player with the higher score, based on audience response and technical accuracy, wins the competition and gets to keep whatever money is still attached to his/her suit.
