Looks like it is meant to be played using the .bat file. Extract the zip to your Gamedata folder and double click the "launch_dragame0.bat" file.
If you're not on windows you can use "map dra_map_0" in the console
I'm going thru the textures for the doongiver level myself, and I can't find the symbols @JoHnNiEE91 was talking about. Are they in another folder? I'm trying to avoid running into the same problem he did.
It has potential, but it needs a lot of refinement. Study 501rst forums they have entire sections dedicated to Vader's details per episode. Again it has some potential, the model's detail in the face and the mechanical limbs etc is VERY on the right track, however the textures are a blurry mess and the suit is all over the place episode(s) wise.
The model has potential, the textures need a lot of work - I do hope you'll continue to tweak this.
