I believe i have found a nice base design for lower levels. I have not added any platforms or turrets because i am going to keep my bubble until i am confident of my design.
To get this design you have to move your OP down to the asteroid field in the bottom of your base view. After that just position 3 miner plats at each asteroid next to it and place your building as you wish. I will try to figure out the turrets soon after some people reply.
I welcome feedback and trolls to tell me whats wrong, cause i am just wanting to see.
