This kit contains 2 frames of plastic components – one containing the components for the central dome, and one containing components for the external tank – and is compatible with every other kit in the Sector Mechanicus scenery range, meaning massive, multi-level, labyrinthine structures can be built for your battles to be fought on. They can even be combined with the Haemotrope Reactor, Promethium Relay Pipes and Void Shield Generator. Your imagination is the only limit – no two gaming tables ever need look the same!
