10 Cloverfield Lane ARG

Howard Stambler's secret, hiding in a shirt

The 10 Cloverfield Lane ARG launched months before anyone knew the film existed. It began with a corporate website for Tagruato, a fictional deep-sea drilling company who's website from the original Cloverfield movie had been sitting dormant for years…until the Employee of the Month page was quietly updated with new honorees, including Howard Stambler (John Goodman). The logo on his shirt led players down a rabbit hole to a password-protected secret chat room Howard built for his daughter Megan, with his recurring exhortation that something terrible was about to happen.

Over six weeks, Howard's secret page led to other websites, chat rooms, a DOS-based survival simulation game, buried physical artifacts, a Chicago dead drop containing a burner phone, and real voicemails from Howard — all building toward the movie's release date, and ending with Howard in the bunker as the film begins.

Building the world fans went looking for

I designed and wrote the ARG, the full narrative architecture and all in-fiction content. Everything a player discovered had to feel like it had existed before they found it: Howard's chat posts to Megan, Tagruato's employee profiles, Denise's Craigslist silverware ad, Nikolai Roza's encrypted warning, the voicemails. Each piece had to hold up to intense scrutiny from some of the internet's most obsessive puzzle-solvers.

• Designed the full ARG architecture across websites, social, phone, and physical artifacts
• Wrote all in-fiction content: chat posts, emails, voicemails, character backstory
• Responded to real-time events, changing story elements on the fly as needed

Designing for scrutiny and balance

ARG players are a specific kind of audience; they will examine every pixel, reverse-image-search every photo, demodulate audio files looking for hidden images, and dig into source code looking for messages. The design challenge is writing content dense enough to reward that scrutiny while staying coherent for the less obsessive fans who are just following along.

A crucial challenge was finding exactly the right tone for Howard's online voice. The main tension in the movie revolves around the question of Howard's sanity. How much of what he's saying is true? How much is delusion? How much are lies? The end of the movie provides those answers. A crucial challenge for the ARG was building a psychological profile and a voice for Howard that would mirror that tension; I had to design a story and a voice for Howard that made logical and emotional sense once the film's secrets had been revealed, without revealing anything that would spoil the experience of the film, all while honoring and staying true to the amazing performance of John Goodman.

The campaign's escalating structure was key: each week Howard's situation got more desperate, with the ARG's in-fiction timeline running parallel to the film's marketing calendar. The Denise Craigslist arc introduced a second character perspective. Nikolai Roza's HAM-radio-encoded satellite image gave the hardcore players a technical puzzle. And the physical dead drops — a buried box in Louisiana with GPS coordinates extracted from hidden trailer frames, a locker in Chicago with a burner phone — created moments that the community experienced collectively and documented obsessively.

A community that didn't want it to end

The ARG generated tens of thousands of Twitter and Reddit mentions, a subreddit with over 6,400 subscribers, and more than 178,000 Unfiction forum views. Fan-created content (apparel, art, music, videos, chart-topping podcasts) reached over 93,000 views. Players reported spending 2–3 hours a day on the ARG.
