It's a great mod! I'm enjoying a lot from this Perhaps large workshops and labs would be also great.
Those will be great!!
One thing it always bug me, was that there are no hallways in other levels, if some one could do maps that add hallways in other levels not in every facility but in a few, for example the hangar, to allow soldier to snipe aliens
or vice versa to allow aliens another entry point to the base!!! more defense options, more strategy required.
of course i do not know if it is possible or not. but strategically it will be a great addition bases with multiple levels.
I can already picture it!!!!!
