It is very simple with a plain geonosis texture and sky, only the 2 default command posts and a large hill/cliff, on top of which is where the republic starts off.
There are seveal CPs for both sides, no neutral, and a reinforcement count of 1000.
This is an omaha beach style map with the CIS/Empire attacking. It's not too large, pretty straightforward. Simple but effective.
