Secret Trove

Walkthrough
This mission is very simple, there are no enemies present that could attack you. Build a Droid Factory, and a Droid of your choice, afterwards self destruct the Droid Factory. The Disasteroids have no attack, and there does not seem to be any time limit to this mission either, so you can simply take your time destroying them while your Mothership mines all the available resources. The Disasteroids are limited to the gray asteroid belt that starts to your left, and proceeds all the way to the top of the map.
