The newly released Map Editor allows players to create their own skirmish maps, and even modify existing maps. Both ground and space maps can be created, and an included plug-in for 3D Studio Max lets players design and import their own models.

Before you can use the Map Editor you'll have to install the 1.04 update, which enables the Map Editor and the use of custom maps, and also implements a number of balance changes and fixes a few bugs.

Update 1.04 can be found on the official LucasArts website.
