This Terrordrome cost me about $80. The base structure is a wooden cable reel. The guns are made out of various moulding, doweling, and plumbing parts. The walls are a wooden landscaping barrier. The red jail is a plastic pipe end fixture. I colored everything with spraypaint. The logos are cardboard Cobra sigils cut from boxes.

The Terrordromes online generally cost over $200. I figured the best way to get one was to make my own. I am happy with the way it turned out. The command center has much more room. The lower level wall made from the wooden landscaping barrier produced a great corridor. The big drawback is no hangar for a Firebat. I use this Terrordrome as the command center and firepower for a larger Cobra Temple that surrounds its backside.
