Star Edit is the map editor tool for Starcraft. Using Star Edit, anyone can make or edit a StarCraft map, and then use it as they see fit.

Star Edit allows players to customize their maps, units, structures, triggers, scenarios, forces, and gameplay through various forms accessible from the menu. However, each customization is specifically for that game, which can become annoying; and the customization does not even come into effect unless the player chooses Use Map Settings rather than Melee or Free for All. Additionally, the triggers seem close to programming. Given the difficulty of Star Edit, customizers must run many tests of each map to ensure quality standards.

Terrains are grouped into distinct sets of terrain, and one group cannot be intermixed with another one:

  • Badlands: Dirt, Mud, High Dirt, Water, Grass, High Grass, Structure, Asphalt, Rocky Ground
  • Installation: Substructure, Floor, Roof, Substructure Plating, Plating, Substructure Panels, Bottomless Pit
  • Ash World: Magma, Dirt, Lava, Shale, Broken Rock, High Dirt, High Lava, High Shale
  • Jungle World: Dirt, Mud, Water, Jungle, Rocky Ground, Ruins, Raised Jungle, Temple, High Dirt, High Jungle, High Ruins, High Raised Jungle, High Temple

There are eight tilesets in all, of which five are available in StarCraft and three are BroodWar only.
