Credits: Me (TimRichter, aka. Freakrules) for the concept, the map and most of the custom textures. Komaock ( http://www.gamebanana.com/textures/3007 ) for the skybox. Superb as usual :D Kloetengott (gaming-models.de) for making the Solarpanel-texture. Nebukadnezar (gaming-models.de) for making the plants.
