Heat Cannon

A Heat Cannon on is a Necron thermal energy fusion weapon similar in function and effect to a Imperial Melta Weapon, and is only ever found mounted as a primary weapon on a Sentry Pylon. Heat Cannons, like their smaller Heat Ray cousins, are weapons of extraordinary power and can reduce the most heavily armoured tanks into piles of molten slag and burn its way through the most heavily protected fortifications at great distances. With every beam it fires, it is capable of vaporising everything in an area with a small blast, and its decent rate of fire allows it to continually bombard an area with impunity.
