The five (Jesse, Petra, Lukas, Ivor and Harper) head up the stairway to a door. Harper then pushes Jesse, Petra, Lukas and Ivor off the platform, and they fall into a game of spleef in progress. After Ivor/Petra and Lukas die (depending on who was saved), Jesse begins using his/her sword, which, unbeknownst to him/her, is illegal. Hadrian, Otto, and Mevia (the rest of the Old Builders) call for the game to be stopped, informing Jesse of the "rules of the game". Fortunately, Lukas and Ivor/Petra respawn as they are forced to "go work in the mines", and Jesse and Ivor/Petra are allowed to stay in the competitor's village.
In the competitor's village, Jesse and Ivor/Petra attempt to get along with their fellow competitors, with some of them mentioning a legend named Tim who supposedly was the only one to be able to win the games. After getting a piece of bread for Facemeat, one of the gladiators, he allows Lukas and Ivor/Petra out of the mines. Harper and Otto also show up, informing the four (Jesse, Lukas, Petra, and Ivor) that they are on their side, and the four then rest for the night.
The next morning, Jesse and Petra/Ivor participate in the next day of the Games. The Green Team calls for a truce, which Jesse can either accept or reject. The Games then begin with a race, which eventually leads the competitors into Gladiator Junction, an area overrun by Gladiators. Jesse is barely able to make it out alive and is able to assist Nell, a Green Team member, to victory. Unbeknownst to Jesse, Emily, also from the Green team, had made a deal with Hadrian to eliminate Jesse, but she didn't follow through. Jesse then is ordered by Slab, one of the gladiators, to meet with Hadrian, and Jesse reluctantly complies.
Inside Hadrian's office, Hadrian talks with Jesse about winning the Games and tells Jesse that Tim is just a story Hadrian made up to keep the competitors motivated. Breaking down a wall, Hadrian reveals that he captured Olivia, Axel, and Reuben (who turns out to be the usher from the first episode). Hadrian then suddenly changes the terms of his deal with Jesse, stating that if Jesse wins, then Olivia and Axel will work in the mines forever, but if Jesse loses, all of his/her friends will be able to leave, but Jesse will have to stay behind. Jesse can either agree to the deal or decline it, and is sent back to the competitor's village. At the competitor's village, Jesse informs the competitors that Hadrian has rigged the game against them, and Jesse can choose to disclose that Tim is not real. They all then rest for the night.
The next morning, everyone participates in the final day of the Games, with "The Walls". Jesse is thrown into an area which basically is just dirt and gravel. After the walls come down, the participants then team up and the Gladiators defect, giving Jesse and the other participants the victory. Just as Otto is about to give Jesse the Atlas, Hadrian and Mevia trap Otto in obsidian and battle Jesse. Fortunately, Jesse wins thanks to "Tim's armor," and Jesse is rightfully given the Atlas. Otto plans to make the games fun again, and Jesse then can convince Emily to go home, help Otto with the games, or join him/her. The six (Jesse, Axel, Petra, Lukas, Olivia, and Ivor) then head home and put their souvenirs on display. As they are about to leave, Jesse and Lukas notice that Ivor has run off with the Atlas and the enchanted flint and steel, and Jesse can decide whether to go after him or let him be.
In a post-credits scene, Hadrian and Mevia spawn in a bedrock world of chicken-sized zombies/zombie-sized chickens (depending on the first choice Jesse made in the first episode). As they both have no way out, Hadrian relieves Mevia of her duties as enforcer.
