Star base guns have strong progressive shields.
The stronger the star base gun is under fire, the more effective are their shield. So 10 attacking spaceships don't do 10x more damage than 1 attacking spaceship, but less.

The weapons strength of starbase guns is 100 and the weapons range is 12.
When the range-upgrade is activated the weapons range is 24. | Astro Conquest | Impressum | Support
