Toxic Zombies were introduced to Guillotine Games' Zombicide game in the Season 2 expansion set, Toxic City Mall. Toxic Zombies differ from Standard Zombies in a number of ways. First, upon elimination, a Toxic Zombie inflicts 1 Wound on its assailants if they are both in the same Zone. This is a free attack called Toxic Blood Spray. Ranged attacks from outside the Zone do not cause this effect. Toxic Zombies exist in all types - Abominations, Fatties, Runners and Walkers. They have the same characteristics and get the same targeting priority as their counterparts but are removed first in Ranged Combat and car attacks. Toxic Fatties come with an escort of two Toxic Walkers. Toxic Zombies do not benefit from the extra activation cards of other Zombie types. Eliminating a Toxic Zombie with a car does not cause a Toxic Blood Spray.
Finally, I'd like to mention how I painted these figures. Normally, I paint my figures using Foundry paints. But for these I also used the Army Painter Zombicide paint sets - Zombie Core Paint Set and Toxic/Prison Paint Set Expansion. I first used Zombie Skin with a wash of Zombie Shader, which perfectly matched the colour scheme of the Toxic Zombies' skin tones in the rulebook. The spikes were painted with Dirt Spatter, followed by Boney Spikes then Brain-matter Beige. The boils were painted with Toxic Boils and highlighted with a 50/50 mix of Toxic Boils and Brain-matter Beige. The rims of the eyes and mouths were painted first with Dead Black, followed by Foundry White 33C for the whites of the eyes and teeth. These paints are quite thick and they give good coverage. I am very impressed with them. I know I will use Zombie Flesh the most and was wondering what to do when it runs out. Unfortunately, these paints can't be bought separately at the time of writing and I don't want to buy another boxed set just to replace one colour. Fortunately I discovered that Foundry Boneyard 9B is a perfect match for the Warpaints' Zombie Flesh. Sorted!
