The term "Zerg rush" originates from the popular real-time strategy game "StarCraft," developed by Blizzard Entertainment. In the game, the Zerg race is characterized by their ability to quickly amass large numbers of units and overwhelm opponents with sheer numerical superiority. A "Zerg rush" refers to a strategy where a player focuses on rapidly producing basic units and swarming the enemy base early in the game, aiming to overpower them before they can establish a solid defense. The term has since become synonymous with any overwhelming and relentless attack in gaming or even real-life contexts, highlighting the strategy's swift and aggressive nature.
