The Thunderfire Cannon is a colossal multi-barrelled weapon. Mounted on rugged tracks it provides long range support for a Space Marine advance. The Techmarine manning a Thunderfire Cannon can set its shells to detonate in a variety of different ways, depending on the tactical situation. Surface detonations are employed against numerous enemies, while airburst shells are used to scour a foe from cover and subterranean blasts are used to send the enemy sprawling, making them easy prey for the advancing Space Marines.

This box set contains one metal Thunderfire Cannon and one metal Techmarine with servo-harness. Techmarine supplied with a 25mm round base.
