After switching to the "vote off" format, the series would alternate between "Battle" seasons, including two seasons of "Battle of the Sexes" and themed "Challenges" which included the "Gauntlet" and "Inferno" seasons. Both the "Gauntlet" and "Inferno" seasons contained "showdown" matches between members of the two opposing teams. The cast member who lost the showdown would be sent home. The "Gauntlet" seasons featured an intra-cast dynamic as teams were forced to vote off cast members within their own groups into the showdown, while the "Inferno" seasons featured an inter-cast dynamic as teams were forced to vote off cast members from the other group into the showdown.
