Starcraft 2 Map Editor

The Starcraft 2 Map Editor is a program that comes along with Starcraft 2. It lets users create completely new content that can be run using the Starcraft 2 Game Engine. This content does not necessarily have to be a normal melee map but can be an entirely new style of gameplay (such as First-person shooters).

To launch the editor go to your Starcraft 2 folder and double-click the Starcraft 2 Editor icon.

Modules
The editor is split into several modules. Each module has a number of tools that allow you to modify a specific part of your map. Learning how to user each and every of these modules is essential to creating a great custom map for your users.
 * Terrain Editor - Edit Terrain and add game objects to the map (such as units and doodads).
 * Trigger Editor - Edit and create Triggers for the map.
 * Data Editor - Edit the Data for your map which defines how objects behave.
 * Text Editor - Edit all the text strings that are used for the map.
 * Import Manager - Import external files for use in the map.
 * Overview Manager - Provides a quick summary about the map.
