StarCraft is Blizzard Entertainment's 1998 real-time strategy game, where the human Terran faction raises its unit cap by building Supply Depots. When that cap is reached, the Terran Adjutant advisor warns the player that more depots are needed, and the clipped error tone became closely associated with that warning in sound libraries as taderr02. As StarCraft matches, streams and remixes spread online, the alert survived outside the game as a shorthand for hitting a hard limit, especially among strategy and PC gaming communities still replaying the classic.
