Nice and original idea. Should work well.

maybe if you could just let us see a few screens... NOW!!! or i throw you off a cliff... mwah hah hah...

There are screens in the first post, just click on the links. But, 'cos I'm really nice, I'll post what they look like below:

Looks good.

Now, I'm all about red and black and fire and doom...
but I would suggest that you do add a little bit of variation to the color scheme. Some ideas are to lighten up some of the reds, add some bright spotlights near dying machinery, units with lightsabers should have blue or green for saber color. If it's a sith, consider yellow. Or a light orange. At least. Pure red and black is cool but not when you spawn, say hi to your r&b buddy, and then walk across the r&b ground past some r&b rubble, kill a r&b baddy, and walk into the black tunnel lit with dim red lights at random intervals.
(that was exxageratish, but i'm just suggesting )
