The third and final challenge involves getting to Planet Doom and beating "Adventure", OASIS co-creator James Halliday's favourite game for the Atari 2600, housed in a castle protected by a forcefield. Other players help Parzival attack the forces protecting it, and Art3mis deactivates the forcefield, but a bomb is triggered by Sorrento, killing all the avatars on the planet. Because Parzival had won a coin earlier, he gets an extra life, plays through the game and finds the easter egg, getting the last key.
He's given a contract to sign for his reward by the avatar of Halliday, but he recognises it's the same one the co-creator of OASIS signed, a decision Halliday had regretted taking. He refuses to sign it, and learns that was the final test - Halliday didn't want him to make the same mistakes. Parzival wins the golden egg, and with it control of OASIS. Sorrento is arrested for the bombing of Wade's stack, and Wade runs OASIS with the other "high five" who helped him win. Innovative Online Industries is forced to stop using indentured servants, and the OASIS will be shut down twice a week, forcing people to spend time in reality.
Continuity mistake: Right in the beginning, Wade hops out a window from his home and starts walking beside it to the edge to climb to the next level down. As he starts walking he passes by another window with a curtain. It then cuts to a closer angle and suddenly the window no longer has a curtain. Also a wire appears on the wall in front of him. And you can tell it is the same house, not a time jump, as the rust at the top of the window frame is exactly the same. (00:01:15)Quantom X
Trivia: In the video that Halliday left behind after his death, you see floral arrangements around his coffin that are in the shape of the Star Trek's Federation symbol and one of the Enterprise. But the really cool thing is his coffin is actually a photon torpedo, exactly like Spock was put in after his death at the end of Star Trek II: The Wrath of Khan. Complete with the blue Federation flag draped over the end of it. (00:08:05)Quantom X
