The video likely worked due to its use of trending topics (zombie apocalypse, viral incidents) and engaging visual content, including the "Umbrella Corporation" branding which taps into popular culture from the Resident Evil franchise. The mix of real-world events and fictional scenarios creates a sense of intrigue and shareability.

The video discusses a Texas government pamphlet about preparing for a zombie apocalypse and then shows viral videos related to zombie-like incidents. It features footage of a car with "Umbrella Corporation" branding, a "zombie outbreak" incident at Walmart, and people in the UK who appear to be zombies.
