The Challenge once featured free agents -- and now, six years later, the hit competition series will have a slew of double agents.

The Challenge: Double Agents, premiering on December 9, offers 30 players attempting to outsmart each other in a game of secrets for their share of $1 million. It's every spy for themselves -- and twists and turns await (as seen in the first look below).

Who will be attempting to seize all of the Challenge glory? Will veterans or rookies -- or one of each -- take home the grand prize? Get to know all of the competitors below, and do not miss the debut of The Challenge: Double Agents on Wednesday, December 9 at 8/7c!
