Very nice and clean... too clean. I'd advise removing one of the cows and 1-2 tanks of each type, or rearranging some of their blocks into L-, H- and other shapes - such a perfect order of rectangles looks suboptimal Also - good luck with the expanded ubase, this thing really needs a fix!
Why would it be suboptimal?
It is the perfect order for storing stuff, to get it in and out quickly.
And btw i did a lot of work on the expanded ubase last weekend. Fix a lot of stuff reworked the rmp routes on all but 3 maps (i checked them they seemed to be ok, 2 of those will get reworked anyway.)
You can find the Version i put together on the last weekend
hereBut make a backup of the original files, because i did not rename them.
I tested it about 20 times to see if the aliens were behaving, and they did pretty good with the new routes.
