It's a map with 2 each stations for each side.
The middle is the circling sentry guns that you have to build,
I think i am going to make a second version were guns are built and added terrains..
{see screenshots}.
I also included a large asteroid fields to drag the enemies big ships..
Starting units:
Rebels:
6 Venator Cruisers accompanied by X-Wings and V- wings in each station.
Empire:
6 Acclamator cruisers for empire accompanied by fighters and bombers..
Hint:
The other empire station is surrounded by 3 pirate build site.
