Yip- I know that they bundled the level editor with the sequel -Alien Breed 3D II - i used to mess about with it and create my own levels.
It was quite primitive and buggy and sometimes a pain to use- but I enjoyed it.
Thing is- i've always wanted a level editor for Alien Breed 3d- the first one! -does anyone know if one exists? -and if so- can i get a hold of it somehow?
