Sci-Fi Fortress Walls, Towers & Cannon Build Kits

Sci-Fi Fortress Walls, Towers & Cannon Build Kits

$14.99

Build the perimeter of your sci-fi fortress.

The radar operator notices the signal before anyone hears the engines. Across the landing zone, the watchtower turns its attention toward the dark ridge. The gate crew clears the entrance while a patrol takes cover along the wall. For a moment, the entire outpost seems to wait. Then a small light appears above the ridge, followed by another. Build the perimeter that stands between the quiet base and whatever is coming over the horizon.

Blast doors, radar dishes and cannon on the parapet. This is the fortified installation your sci-fi army has been fighting over without ever having anywhere to stand.

Each option is a brick compatible custom build kit, supplied as its own bagged build with the pieces for that model. Walls, corners, gates and towers share the same connection points, so the perimeter runs straight, turns at a bunker and opens at a vehicle gate. One kit works as a display piece, several become an entire fortress footprint.

The range includes the Sci-Fi Fortress Wall with Blast Doors, the Sci-Fi Watchtower with Radar Dish, and the Heavy Anti-Armor Cannon, sold as a five pack.

Testimonials

  • I was three figures short of finishing a diorama I'd been working on for months. Couldn't find the pieces anywhere reasonable. Brick Bros had exactly what I needed. fit perfectly, finished the scene the same week it arrived.

  • My son wanted a whole squad and the brand-name versions would've cost a fortune. These were a fraction of the price, snapped right onto his existing sets, and I didn't have to worry about the material. He hasn't put them down.
