For the better graphics:
-vertex paint
-bump maping
-specular highlights
optional
-new compiler of map and bots (without restrictions to the number of objects, vertex etc.)
-better use of the alpha channel. Increase the distance generate the graphic (j can't see good distant textures with alpha channel)
-dynamic shadow map
-soft bodies
-bones animation
-3d objects animation from blender or 3ds
-editor join the bots, map, textures, compiler and scripts. Use more 3d formats. (fbx, lwo, ase, blender format)
-shadow map from file without restrictions.
-support large textures (8000x8000)
