I currently have a trainstation blueprint that I put down as and when I need to send artillery trains out to clear some nests. Unless I get this blueprint real close to the nests it isnt automated, anybody have a better system for expanding into unclaimed areas?
You can use the remote control to manually target artillery. Much longer range.
Other than that, spidertrons!
Or have a friend who enjoys fighting and mind other things, my preferred approach :D
