The season was once again hosted by Mario Lopez and featured Layla Kayleigh as the backstage correspondent.
Team Millennia, who was eliminated during the Season 2 casting special, returned as one of the nine official dance crews.
Then, the judges chose the bottom three crews to compete in a sudden death dance battle to "Live Your Life" by T.I.
Rynan "Kid Rainen" Paguio from JabbaWockeeZ temporarily guest judged in place of JC Chasez, who later returned the following episode.
The episode started off with a group performance, choreographed by Napoleon and Tabitha D'umo, featuring Ludacris' "What Them Girls Like" and Beyoncé's "Single Ladies".
The three remaining crews had to demonstrate their versatility by creating a routine that incorporated five different hip hop dance styles.
