Walker Creek was an alternate reality game consisting of over 100 videos, 7 websites, and numerous interactive elements across social media, email, and phone. After its completion, it was re-edited and released as a feature film, and a feature-length documentary about its production was created.

Over 1000 people engaged with the game over the course of thirteen months.

Walker Creek, WA is a small town with a dark secret: a hidden society of parasitic aliens taking over human bodies and turning them into shapeshifting creatures known as The Hosted. Over the course of the game, players sought to uncover the truth about the infestation in Walker Creek, and join a secret rebellion to bring down The Hosted.

Walker Creek was presented immersively across platforms. Video segments were filmed and edited in the style of live broadcasts and in-world cameras. The YouTube channels that hosted videos were managed by characters in the story, who each had social media and email accounts which could be contacted. Gameplay took place on multiple in-universe websites including three blogs, a town website, and four unlockable websites - as well as two phone numbers, where players could sometimes talk to a character in real-time. A thriving Discord community for players was maintained over the course of the game.
