The Challenge: All Stars is a nine-week spin-off which features the return of 22 of the most memorable and recognizable names of The Challenge as they fight for a share of $500,000. The season was filmed in the Andes Mountains of Argentina in February 2021. This is the first season to stream exclusively on Paramount+.
Twenty-two of the most iconic, fiercest, and boldest Challenge All Stars from the original Real World and Road Rules series have been selected to return for a second chance at the ultimate competition. All have history, but when relationships are the key to survival, will these legends be able to form new bonds, or will their past lead to their demise? With $500,000 and their legacies on the line, which of these All Stars will prove they are still the best of the best?
Each challenge will be played as either pairs, teams, or as individuals. In individual, the winning player of the designated gender will win safety, while the opposite gender will win the Lifesaver. During team challenges, each team will nominate two team captains. The winning captains will each recieve power. The winning captain of the gender designated for the elimination Arena will be safe from elimination, while the captain of the opposite gender will receive the Lifesaver. The losing captain or the last-place player will go into elimination, and the rest of the house will vote in their opponent. In the Arena, the player with the Lifesaver can choose to nullify the house vote. If used, the house will have to vote in their replacement. If not used, the two players will compete in elimination. The winner stays in the game while the loser goes home.
After four eliminations, the Lifesaver will no longer be in play. All eliminations going forward are played as pairs.
In the Final Challenge, one player will take home $500,000.
- Lifesaver: The winning captain of the gender not designated for the Arena will have to choice to save the house vote from competing in elimination.
