Secondary asteroids

Once players acquire the science of Domain, they can capture up to 5 secondary asteroids.

To do that, players need to find an empty asteroid (or the asteroid that belongs to other Astro Lord) on their radars and then send out an attack to capture it.

In order to take control over the other Lord’s asteroid, players need to destroy his/her Star-Base.

Other players can not see the Astro Lord's secondary asteroid unless he/she builds a Star-Base there.

If players do not prolong the lifetime of the secondary asteroid, it disappears.
