The sound comes from Serious Sam: The First Encounter, released in 2001 by Croteam, where the Beheaded Kamikaze became one of the series' most recognisable enemies. Unlike silent attackers, he announces himself with a long scream that gives players a few seconds to react before he detonates. The clip spread through gaming videos, montages and soundboards because the yell alone signals danger without needing any visuals. It remains a staple in later Serious Sam games and is still used online to mark anything charging in recklessly toward a certain explosion.
