KKnD2 Terrain Editor is unofficial advanced map editing tool designed for KKnD2: Krossfire. It's unique feature is operating on layers (like in Photoshop), so it has much greater potential than the original editor. There is also Map Generator that creates random maps.

You can't place any "playable" objects (agents) in Terrain Editor. To do this, you must export your project to *.km format and edit it in KME (original editor) or KME 2.0 (unofficial editor, also called "kmpe").
