OUR TAKE / EDITORIAL
Why it's on the wall
A laptop ad with a comb for a sword, CGI artists for enemies and a power-up that makes them dance.

GAME BRIEF
What's the game?
Mustache Protocol opens in a barbershop, where the TV news says mustaches are under attack and Henry, talking in the first person the whole way, says “I know that CGI artist...” Then it's a side-scrolling brawler on Jersey Island, under a sign that calls it Henry Cavill's birthplace: you walk the harbor street in gold armor with a giant comb for a sword, fight CGI artists who come at you with scissors, and pick up the mustaches they drop; later the fight moves to a jungle with film-set scaffolding behind the trees, then to a Hollywood studio lot, where a casting agent says the new role “must be cleanly shaven” and offers to shave “that caterpillar” off herself. You get three hearts and four special moves on I, O, K and L. Arm Reload gives Henry super punches and a few seconds of invincibility, and Tank Attack puts him in a blue tank top under a disco ball while the bad guys stop fighting and start dancing. The premise riffs on the mustache that was digitally removed from Cavill's face, as Superman, for the Justice League reshoots.
BEFORE YOU PLAY
What to expect
Henry Cavill made it on his Googlebook for Google's laptop campaign, and Google's behind-the-scenes episodes show him building it with the laptop's AI tools (Antigravity, Rambler and Magic Pointer, per Android Authority). It's free, with no sign-up or download, on Google's own site. It loaded about 31 MB to the title screen and about 88 MB by the end of our run, in Chrome on Windows. Google says it donates $11 to Movember each time the game is played from November 11 to 30, 2026, up to $500,000. The settings list gamepad and touch controls; we didn't try a phone.
Controls: Keyboard: A and D move, Space jumps, J attacks, E interacts, Esc pauses. Special moves: I (Release the Hounds), O (Arm Reload), K (Tank Attack) and L (Works For Me). The settings also list gamepad and touch controls.
