Henry Cavill‘s Mustache Protocol video game is real, playable, and, to the surprise of its first reviewers, actually good.
Brands have started treating games as more than a novelty, with Wendy’s new RPG clocking in at around 15 hours. Cavill’s project looked flimsier, a Googlebook ad masquerading as a game, built with AI tools, whose early images even sparked false rumors it was already playable. Now it’s out, and according to reviewers, it actually holds up.
Henry Cavill’s AI-built mustache game launches to surprisingly warm reviews
Google released Mustache Protocol on November 11 alongside the final episode of its behind-the-scenes series, making the game free to play in a browser on desktop and mobile.
The 16-bit side-scroller tasks players with stopping rogue CGI artists from erasing every mustache on the planet, a nod to the mustache Justice League infamously scrubbed off Cavill’s face with CGI.
As far as reviews go, early impressions were warm. Digital Trends called it retro, silly, and “a lot of fun,” with its reviewer admitting to some initial skepticism, only to find mechanics that were easy to learn and an AI-built game that didn’t crash.
Inverse went further, describing it as “both hilarious and fun to play” for anyone who misses old-school side-scrollers.
In terms of gameplay, Mustache Protocol is a retro action platformer, with players slicing through zombies using a comb-shaped sword. Grabbing a steak bulks Cavill up, unlocking punches and his famous arm reload, while his Warhammer-style armor has a red mustache emblazoned where Superman’s sigil would sit, and his dogs Kal and Baggins pop up in cameos.
Cavill pieced it all together over three episodes with Googlebook’s AI tools, using Antigravity to turn his spoken ideas into game mechanics.
There’s a charitable kicker too, as Google is donating $11 to men’s health charity Movember every time someone plays through November 30, up to $500,000.
Cavill isn’t the only one building with Google’s AI either, since the company recently started letting anyone make their own Android apps with AI, no coding skills required.
