Next to join the ranks of my Necrons for Warhammer 40k is a Cryptek, accompanied by a swarm of Canoptek Scarabs. Carrying a chronometron, he can slow the flow of time, allowing his unit to evade incoming fire. Anything that makes Necrons harder to put down and more likely to get back up is a must have in my view.
Again I stuck with a mostly metal body and painted the back armour in black. Nothing too ostentatious on my tomb world.
For the Scarab swarms I am using the old metal variety which I always liked. With their little skull faces and mandibles they look more aggressive than the newer models.
