Obsession arrived as unknown horror: no franchise, no built-in fandom, just a first-time director's original story. To introduce audiences to its world before opening weekend, we built an original interactive game experience (Mission Quest) inside Discord that let players live inside the film instead of watching a trailer for it. Players took on the role of Bear, broke a cursed "One Wish Willow," and raced against a countdown to escape Nikki's obsession. The experience pulled details straight from the film, including in-character voice recordings from actress Inde Navarrette and Michael Johnston, as well as props and Easter eggs recognizable to anyone who'd seen or would see it, so it felt like a true extension of the movie's world. 1.1 million players stepped into the Mission Quest experience. Many came back more than once, logging 1.7 million total plays and over 15 years of combined time spent inside Obsession's world.
