Unlike the package of separate tools that were released for Battlefield 1942 and Vietnam, the BF2 Editor consolidates all the tools a Modder will need into "subsections" of one Editor, allowing you to do pretty much everything from the same application.

The Level Editor subsection is where you do most of the layout work. In this subsection, you place your objects, spawn points, control points, static effects (such as fires, smoke, or whatever), as well as undergrowth and overgrowth. In the Level Editor you also define boundaries, triggers, playable areas and more. Alongside the Level Editor is the Terrain Editor subsection, in which you can sculpt the terrain and paint ground textures. One really handy feature of the Level Editor is that you can switch to "soldier cam" to get a view of what the map will look like during normal play without having to save the level and load it in Battlefield 2.
