Progress report:
I finished a prototype for turret internals. I did it for the one turret facing the base station, and built a maintenance room around it. I presume we're presuming that there is a central control room presiding over all the turrets from one location ("Gunnery control, open fire!"), and not Star Wars Ep. 3-esque individually-manned turrets? Feedback please.

Also, I outlined a main hall on the deck above the current halls; seems to me that one hall works better than two in the narrower width available when it passes through the necks. Its floor is 8 blocks wide instead of 7 for the other decks; we can lower it to 6 if 8 is too wide. Let me know what you think.
Finally, I just added a possible type of elevator (zipper elevator!) to the front bulkhead of the CIC (one could go on the rear bulkhead of the CIC as well)... it uses pistons, but the game is way to laggy for me to be a valid tester - it
works, but only when my computer gets the signals from the server in time, which usually only happens ~10% of the time. Could someone test it out and let me know if it works often enough to keep?
Miscellany so I don't forget them:
- "Emergency" access stairwells near any elevators (and in many other places), for those times when the ship is under attack by that vicious alien race, the Laaag!!
- Generally, maintenance areas should only have ladders for ascending/descending, not stairways.
- Gunnery Control room (with labeled stations for each turret?
)
