The kit is made up of several large chunks of resin. There are four "legs" that attach to a main body, and a "head" that serves as an entrance. In fact, if you look at it upside down, it's a turtle!
The turret itself is free-sitting inside the main body. You could glue it if you want, but gravity will hold it down in the middle and allow you turn it as needed.
It's quite a monstrosity of a kit. As you can see, an entire squad of Legionnaires doesn't even fill the gap between two of it's legs (that's what she said!), and even the mammoth Hades dwarves in comparison to it.
As with the monorail kit, there's no official rules pushed for this thing yet, but expect some PDF downloads on Hawk's website in the next week or two. Until then, you can always give one player the monorail, and give the other player than cannon, and see what happens =)
