The StarCraft Campaign Eitor, commonly known as StarEdit, is Blizzard Entertainment's official level editor for StarCraft and StarCraft: Brood War. The editor's trigger system allows users to change maps radically and create custom map scenarios. The StarCraft community has constructed new editors and functionalities that grant users even more power to modify the game. The company Microstar sold a CD with new levels created with the StarEdit feature, but was forced to stop when Blizzard won their court case against its distribution.
