dwez I had an idea today as I was finishing my the heavy weapon for my second tactical squad. how about a section of wall that could slot in between the platforms. I know the idea was for walkways up in the air but we imperial fists love nothing better than a well fortified base and floating walkways just don't stop the horrors of the universe quite like a solid wall. :-)
I am going to try to knock to gather 2 of your design and work out the wall section right now.. be back in a few hours with something built hopefully
