The Empire army employs several black-powder weapons in its arsenal, including the Helblaster Volley Gun and the Helstorm Rocket Battery. The Helblaster Volley Gun is one of the most infamous black-powder weapons ever invented, its devastating firepower able to tear apart an entire regiment in one thunderous volley. When the rockets of a Helstorm Rocket Battery do manage to land on target the results are devestating, with entire regiments blown apart by an earth-shaking cascade of shrieking, explosive rockets. This box set contains one Empire Volley Gun (which can be constructed as a Rocket Battery) and three crew members.
