Henry Cavill's 16-Bit 'Mustache Protocol' Game Is Live — Every Play Donates $11 to Movember

Henry Cavill has built a video game, and playing it raises money for men's health. Mustache Protocol, a 16-bit adventure Cavill made on his Googlebook, is live now, and from November 11 to 30, Google will donate $11 to Movember for every game played, up to $500,000.

Cavill's creative process played out over the past few weeks in a behind-the-scenes series. In the first episode he designed a handlebar-mustachioed hero using Magic Pointer and Quick Access. In the second he used Rambler to create superpowers and health boosts. In the finale, he put the finishing touches on the game, previewing a smooth, 70s-style track on his Android phone, moving it to his Googlebook desktop with Continue On, adding custom beats with a drum pad and BandLab, recording baritone vocals, and using Rambler and the agentic platform Antigravity to stitch together the final visuals, level layouts, and interactive elements.

The game itself is a retro-style quest across three levels, sending players out to stop a rogue CGI agent from erasing every mustache on the planet. It plays directly in a web browser or on desktop and mobile, with simple arcade controls to move, jump, and swing a mustache-comb sword, and Cavill packed each level with power-ups and Easter eggs to find.

Every play between November 11 and 30 triggers the $11 donation, supporting Movember's work on men's mental health, suicide prevention, prostate cancer, and testicular cancer. The game is playable now at googlebook.com/henry, alongside all three behind-the-scenes episodes.
