The creators of Stranger Things revealed that the season five finale's climactic battle was influenced by the video game Baldur's Gate 3. The Duffer brothers drew on the game's Dungeons & Dragons roots to shape the team's collaborative fight against the Mind Flayer. This inspiration highlights the show's ties to tabletop gaming traditions.
Stranger Things concluded its nearly decade-long run with a two-hour season five finale that aired on New Year's Eve. The episode featured an epic battle involving key characters like Eleven, Vecna, and the Mind Flayer, set in the wasteland of Dimension X. This confrontation pitted nearly the entire cast against a colossal spidery manifestation of the Mind Flayer, with Vecna residing inside the beast.
In an interview with Variety, the Duffer brothers explained the creative process behind the showdown. Matt Duffer stated, “We were thinking about D&D, and I was playing Baldur’s Gate 3 [while creating the finale], and we felt it was very important that the only way for them to defeat it was for the entire party to work together.” He continued, “Everyone had fully realized—either through self-acceptance or they’ve resolved all their various issues—moving into that final battle, they’re absolutely primed. They’re the ultimate team, and it’s the party working all together to defeat this thing. And they each have their own individual skills, right? And that’s where I go back to Dungeons & Dragons, and something like Baldur’s Gate. Because that’s how you take down these monsters that seem otherwise unstoppable.”
The brothers also noted that “lots of video game references were applied to that final battle,” though they did not specify further examples. Both Stranger Things and Baldur's Gate 3 share roots in Dungeons & Dragons, with mind flayers playing central roles—euphemistically in the show and literally in the game.
Swen Vincke, head of Larian Studios, the developer of Baldur's Gate 3, reacted positively by resharing the news on Twitter with the comment, “That’s pretty cool.” The Duffers dismissed fan theories about a bonus episode or unrevealed “true” finale, stating, “Obviously, that’s not a real thing.” This revelation underscores the blending of video game mechanics into television storytelling, emphasizing teamwork and character growth in overcoming formidable foes.
