The Hellhammer Cannon is a heavy siege cannon mounted on the Stormsword and Hellhammer Super-Heavy Tanks. It has shorter barrel with heavy-gauge suppressors which allow it to fire extremely high-calibre shells without ripping the vehicle apart. The shells fired by a Hellhammer contain an unstable sub-atomic charge at their core, allowing them to smash apart enemy armour and emplacements with the fury of miniature nuclear explosion.
