Netflix dared Zack Snyder fans to unlock the first 15 minutes of Army of the Dead from an “uncrackable” vault buried in the Nevada desert—using only an emoji. Teased with cryptic social posts, viewers teamed up with Dave Bautista’s character and Snyder himself, sending thousands of emoji commands to excavate the vault in real time. A final explosion unleashed the footage—and a digital zombie apocalypse—granting fans a 32-hour window to watch. With over 10,000 emojis sent, 22,000 live viewers, and millions of global impressions, this interactive livestream propelled Army of the Dead into Netflix’s top 10 openings.
