As with the other races, the Zerg are the subject of a full single-player campaign in each of the series' real-time strategy video games. Zerg units are designed to be cost-efficient and fast to produce, encouraging players to overwhelm their opponents with sheer numerical advantage. Since the release of StarCraft, the Zerg have become a gaming icon, described by PC Gamer UK as "the best race in strategy history". The term "Zerg Rush", or "zerging", is now commonly used to describe sacrificing economic development in favor of using many cheap, yet weak units to overwhelm an enemy by attrition or sheer numbers. The tactic is infamous; most experienced real-time strategy players are familiar with the tactic in one form or another.
