The Palace was a local arcade in Hawkins. It featured a variety of games, including Dragon's Lair, Dig Dug, Centipede, Galaga, and Pac-Man, as well as several pinball games. Keith worked at the arcade.
On the night of October 29, 1984, Mike, Dustin, Will and Lucas went to the arcade and played a game of Dragon's Lair with Dustin at the controls. Even though Dustin earnestly tried to defeat the dragon by managing to get a sword to his character, he ultimately lost with his character getting killed by dragon fire. As Lucas boasted his high score on the game, Dustin countered that he still had top scores on Centipede and Dig Dug. However, the arcade's employee, Keith, overheard their conversation and told him that his top scores were topped by someone named MADMAX.
As they debated with him to reveal the player's name, Will unexpectedly noticed that it was snowing outside. However, when he turned to ask his friends, he was drawn to the Upside Down with the arcade seemingly abandoned and his friends missing. Will observed a red thunderstorm coming for him, before Mike, unbeknown to his visions, lapsed him out and they returned to playing.
Later on, with Keith's help at the arcade, Lucas deceived Max into thinking that the Dig Dug arcade cabinet was out of order and brought her to a separate room. It is here where he revealed the mysterious events that transpired the previous year, regarding Hawkins Lab and Eleven, in a way of apology for why his friends were excluding her. However she questioned the story’s legitimacy.
Behind the scenes
The Duffer Brothers revealed that their very first idea for the second season was to introduce a local arcade, stating that "We love board games but in truth have spent more time playing video games, so we wanted to weave them into the fabric of the show."
All the games on set were playable, so the cast and crew were able to play them between takes.
