I dont have a screen shot either but when the starbases first opened if you sat down in the middle of Ops, your legs disappeared through the floor. The first thing I could think of was to yell, "Medic"! Another fleetmate was with me as we inspected the crew and got a good laugh out of it.
Enter Nukara system (base camp), take some missions and jump over the railing to the right of the mission officer.
You will end up on top of a cliff where you can spam turrets and snipe to your heart's content.
I christened my new fort "Fort Pillow"
The funniest thing I saw at Nukara was this HORDE of drones someone had somehow created. There had to have been at least 2 dozen!! They flew around in a pack and exterminated Tholians left and right! But yeah, Engy bunkering makes Nukara much more fun!
