Yesterday I've managed to put together some models for my Renegades Detachment. Seven Renegade Infantrymen, and six Zombies.
Infantrymen made using Cadian Shock Troops and Kromlech Gasmasks, Zombies are mix of Cadians and plastic Zombie Regiment from WFB.
I hope I'll have enough time to prime and paint them this evening. The problem with horde armies is exactly this - I have to paint A LOT of models.
