Zerg Rush

In video games, rushing or rushdown is a battle tactic similar to the blitzkrieg or the human wave attack tactics in real-world ground warfare, in which speed and surprise are used to overwhelm an enemy's ability to wage war, usually before the enemy is able to achieve an effective buildup of sizable defensive and/or expansionist capabilities. It is also known as a zerg or zerg rush, a term which originated in the video game StarCraft to describe a common strategy for players of the Zerg race.
