Lusth returned for a fourth time in the 34th season, Survivor: Game Changers. This made him one of only four contestants at the time to ever compete on Survivor four times -- the others being "Boston Rob" Mariano, Rupert Boneham, and fellow Game Changers contestant Cirie Fields. On Day 16, Lusth attended his first Tribal Council, where he joined the majority in voting out two-time winner Sandra Diaz-Twine. He had to go to Tribal Council again on Day 18, when he joined the majority in eliminating Jeff Varner. He was ultimately blindsided on Day 24 for being too big of a physical threat. He placed 12th and was the second member of the jury. At Final Tribal Council, he praised finalist Brad Culpepper for his gameplay and voted for Culpepper to win, although Sarah Lacina would ultimately win the title of "Sole Survivor."
