The Challenge is about to make the holidays really messy for some of MTV’s personalities. In the Season 27 trailer that MTV is sharing first with Us Weekly, 14 people from the network’s various reality series go up against their family members for a chance to win $350,000 on the competition.

“This season is going to be unlike anything we’ve done before — we’ve paired you up with your family,” host T.J. Lavin reveals in the video. What follows are some seriously strong feelings.

As the relatives — which includes siblings and cousins — face off, they start the new season, which is set in Bodrum, Turkey, totally supporting their blood.

“Family digs deeper than any friendship!” insists one player.

That may be true — until family potentially jeopardizes one’s chance at the fat cash prize. According to MTV, contestants will both fight with and against their family, and that the players’ fates are tied to their kins’. As the trailer shows, it doesn’t take long before the contestants go from saying “blood means everything” to “blood means nothing” with this twist.

The new season will also present some action-packed and fear-inducing challenges, including jumping between moving vehicles, terrifying falls from extreme heights, having snakes slither around one’s head, and much more.

This go-around’s contestants will include Johnny Bananas from Real World: Key West, Aneesa Ferreira of Real World: Chicago, Camila Nakagawa from Spring Break Challenge, Christina LeBlanc and Dario Medrano from Are You the One? Puerto Rico, and others.

The Challenge: Battle of the Bloodlines kicks off Wednesday, Dec. 2, at 10 p.m. ET on MTV.
