Mods introducing new content into the game.
New Ores and resources as well as machines.
Wasn't a better idea let bots dig in construction radius instead? They are construction bots, after all...
The reason it's limited to logistic radius is because of walls. If you have roboports on your walls, your robots may regularly go deep into biter territory and get nommed.
Now available as a setting.
