ForgeWorld hot of the presses... Let's take a look!!!
Resembling monstrous, artificial insects enfolded in shadowed wings of tenebrous force that propel them through the skies, Canoptek Acanthrites are murderous Necron constructs created for a single purpose – the destruction of those who have dared to claim the worlds of the ancient Necron empire as their own. Their agile, coiling tails are tipped with hyper-phased voidblades and they are armed with high-powered thermal cutting beams, and this potent armament allows them to carve and dissemble solid matter with horrifying speed. Unsurprisingly, when these devastating weapons are turned upon frail flesh the results are terrible to behold.
Canoptek Acanthrites are often encountered in the vanguard of Necron assault spearheads and extermination campaigns, and their numbers vary from a mere handful to vast hosts of these abhorrent machine-locusts, capable of stripping a city down to rubble and slaughtering its inhabitants in a merciless tide of destruction.
