I'm already implemented an Cargo Ship-Crane, that will deliver all humans buildings in the upcoming game version 1.3. So I can add it on the space level for Dreadnoughts support.
I've never played a game earth 2150-2160, so I need to check it.
also question, is it just me or is it that i cant control more than one at a time?
No one can select multiple Dreadnoughts by rectangle selection. But in upcoming game version 1.3 you will be able to add second Dreadnought into selection by pressing and hold LeftCtrl + LMB. But that is not effective for their combat management on the small levels. Unlike other games they have real scales and weapons ballistic based on physics. So, without accurate navigation and formation you can occur wrong collision and friendly fire. Generally each faction can build only one Docking platform + one Dreadnought as unique super-unit yet. Space mission is exception.
I'm post in vip forum a video that shows how to win space mission in 5 minutes.
It is based on upcoming game version 1.3, but generally, tactics is the same.
