Binary Homeworlds: Difference between revisions

When a star system contains four or more pyramids of the same color, it becomes '''Overpopulated''' and unstable. Either player can then declare a catastrophe and return all pieces of that color from the star system to the bank. If the star itself gets returned to the bank as a result of this, then any ships of all colors that were at that star system get returned to the bank, as well. Players are not required to declare the catastrophe.
