Here's a couple WIP pics of the Gantry system.
There's a straight section, L section, T section and 4-way section.
I'll be making railings to fit each section, plus armored plates that can attach to the railings.
I'll also be making a straight section with a wider center part so more troops can fit on it.
The pillars that hold it up will look organic, and I'm going to try to get end sections that will fit onto the buildings, so when you have the gantry meeting up with a door it looks like it's part of the structure.
