Contestants

Format

Double Agents features a main challenge, a nomination process, and an elimination round. This season had players competing in male-female teams of two, initially selected among themselves at the conclusion of the opening challenge. These teams frequently changed throughout the season due to the nature of the game. 
Daily Challenge: Players compete in a main challenge in pairs, where the winning team forms the Double Agents.
Nominations:  Players, besides the Double Agents, participate in nominations and must vote for one pair to participate in the elimination round. They are given a chance to discuss the nominations before voting  privately and as individuals. The team who receives the most votes are "compromised" and  will have the player of the designated gender compete in the elimination round. 
Double Agents: Following nominations, the Double Agents are shown the nominated team, as well as which individuals voted for them. At the Crater, the Double Agents vote for a second team to compete against the nominated team in the elimination round, where the player of the designated gender will participate. The Double Agents may also volunteer for elimination instead of voting for a team. 
Eliminations (The Crater): Following the Double Agent's votes, the gender that participates in the elimination round is disclosed. The player of the designated gender of the nominated team competes in an elimination round against the same-gender player of the team selected by the Double Agents, or the volunteer from the Double Agents. The loser is eliminated while the winner receives a Gold Skull and remains in the game. Additionally, the winner is given the choice between remaining with their current partner, or selecting any player of the opposite gender to become their new partner excluding the Double Agents.

Twists
Gold Skull: Similar to the "Red Skull" from Total Madness, winning an elimination round earns a player a Gold Skull, a requirement to compete in the Final Challenge. Unique to this season, there are only 10 skulls available - five for each gender. Once all five skulls are obtained for a gender, the only way to attain a skull is to defeat a player possessing a skull in elimination.
Rogue Agents: A player without a partner at any point in the game is classified as a Rogue Agent. Rogue Agents do not compete in the next daily challenge and are ineligible to be selected for elimination. Once a player of the opposite gender also becomes a Rogue Agent, the two contestants form a new team and compete as usual.
Infiltration: The winner of an elimination round may select any player of the opposite gender (excluding the Double Agents) to become their partner. In the event that a player in an existing pair is chosen, their former partner either chooses a new partner between the remaining agents without a partner, pairs up with the agent without a partner, or becomes a Rogue Agent, depending on numbers. 
Security Breach: Two "Security Breach" twists were enacted throughout the season. 
Reactivated Agent: In Episode 5, eliminated contestant Ashley Mitchell returned to the competition due to the number of female medical disqualifications.
Double Elimination: In Episode 11/12, a Double Male Elimination occurred in which two male players were eliminated. The two teams that received the most votes during nominations were compromised. The Double Agents then had to vote two teams into the Crater to compete against the compromised teams, or could volunteer against either compromised team.

Gameplay

Challenge games
Decryption: Played in male and female heats, contestants race up a volcanic mound to reach a capsule with a color code encrypted on it. They must memorize the code before returning to their station and duplicating the sequence, by connecting colored wires. The first player in each heat to correctly duplicate the sequence and detonate their station wins, however, the individual with the fastest overall time earns the ability to select their partner and become the Double Agents.
Winners: Aneesa & Fessy
Ice Spy: Teams swim through glacial water towards a boat to retrieve a block of ice with a "kill" capsule frozen inside, before returning to shore. They must remove the kill from the ice using an ice pick, and can place the kill in another team's station. Once a team receives three kills, they are eliminated from the challenge, however, they can still place the kill they currently possess. The last team standing wins.
Winners: Aneesa & Fessy
Road Kill: Played two teams at a time, teams begin on the back of a moving truck. They must push their opponent of the same gender off the truck and onto the surrounding safety nets without timing out. The last player with any body part still on the platform wins the matchup for their team. The team that pushes both opponents off the truck the fastest wins the mission.
Winners: Kaycee & Leroy
Drone Control: Played two teams at a time, one teammate wears a VR headset connected to the camera of a drone. They must direct their partner, who flies the drone using a controller, towards a number code at the opposite end of the tunnel. Once they obtain the sequence, the player wearing the headset must solve a binary puzzle before entering the code into a tablet. There is a ten-minute time limit before teams time out. The team with the fastest time wins.
Winners: Devin & Tori
Agent Down: Played in two heats of six teams, the female partners begin harnessed on a ledge on the side of a platform while their male partner begins on top of the platform. The male players must pull 200 metres of rope out of the platform before they can hold onto their partner. The ledge drops after an undisclosed period, however, the females can still hold the platform to avoid falling if their partner has not finished pulling the rope. The team that holds on the longest wins.
Winners: Big T & CT
Smuggle Run: Teams carry a heavy cylindrical capsule on their shoulders and complete a five-mile race. Along the way, they must use their capsule to climb over a wall and solve a magic hexagon puzzle before reaching the finish line. The first team to cross the finish line wins. In addition to becoming the Double Agents, the winners also receive a cash prize of $6,000 each and a P3 Portable Protein reward.
Winners: Jay & Theresa
Aerial Takedown: Played in male and female heats of five players. Players begin on a cargo net being dragged by a helicopter, and must push their opponents off the net into the water below without timing out. The player who pushes all their opponents off the cargo net first wins the heat, however, the player who achieves this the fastest wins for their team and becomes the Double Agents.
Winners: Kaycee & Leroy
All Brawl: Played in three phases, each phase requires players to enter a mud-pit and obtain an X-shaped relic. The winners of each phase advance to the next phase. The team that wins the third phase wins and becomes the Double Agents.
In Phase One, five players of the same gender at a time enter the pit and must find the relic in the mud, escape the pit and cross the finish line with the relic to advance.
In Phase Two, the heat winners of the same gender from Phase One must wrestle the relic away from their opponent and bring the relic out of the mud-pit to advance.
In Phase Three, the individual winners from Phase Two and their partners must wrestle the relic out of their opponent's hands, where competitors face-off against their opponent of the same gender. The team that has both players win their individual matchup wins.
Winners: Kam & Kyle
Interrogation: Played in two heats, with each heat containing of one member of each team. Players begin standing on a platform above water, holding onto an overhead bar. One at a time, they are asked a true-or-false trivia question. If they answer correctly, they must select another player to have their bar tilt forward, making it more difficult to hold on. However, if they answer incorrectly, their own bar tilts forward. Players are eliminated if they fall in the water or hold onto the side of the apparatus. The last player standing wins their heat, while the player who answers the most questions correctly, or holds on the longest, wins for their team. In addition to becoming the Double Agents, the winners also receive a cash prize of $5,000 each.

Final Challenge

Day one
First Leg: Teams must complete a three-mile run across Iceland's undulating terrain to reach the first checkpoint.
Checkpoint 1 (Decryption): Once each pair arrives at the checkpoint, it is announced they would compete in a revisit of the opening challenge. Played in male and female heats, players must race up a volcanic mound to reach a capsule with a color code encrypted on it. They must memorize the code and return to their station to duplicate the sequence by connecting colored wires. The player with the fastest time from either heat wins and earns the opportunity to infiltrate any team and select a new partner.
Winner: Amber B.
Second Leg: Teams must complete a two-mile run along Iceland's coastline to collect a key, before proceeding to the next checkpoint. Teams begin in intervals based on the order and time they completed the First Leg.

Episodes

Reunion special
The two-part reunion special aired on April 28 and May 5, 2021, and was hosted by former NFL player Vernon Davis. The cast members who attended the reunion were CT, Nany, Kam, Cory, Leroy, Amber B., Kaycee, Josh, Devin, Tori, Aneesa, Fessy, Jay, Ashley, and Amber M. Big T, Kyle, Nelson, Nam, Gabby and Darrell also appeared via satellite.

Impact of the COVID-19 pandemic
Double Agents was filmed in Iceland amid the COVID-19 pandemic, where precautions took place to ensure the safety of the cast and production. Both cast and crew were tested for COVID-19 every three days and were required to undergo quarantine prior to the filming of the season. Preparation for the show took production over ten months (longer than most other seasons) and filming locations were scouted virtually due to international travel restrictions. While the international crew occupied a hotel, hired Icelandic locals would instead return home at the end of the day to maintain a bubble, and were kept separate from the cast through a tiered system represented by colored bands. Showrunner Emer Harkin revealed that production was required to wear PPE and remain six-feet apart from cast members. Harkin also revealed that unlike other seasons, where the cast recreated at local venues between challenges, an on-premise club separate to the house was built as an alternative to maintain the filming bubble. During the nine weeks that the season filmed for, none of the 3,000 conducted COVID-19 tests returned positive.
