The Red Ghoul - One of the rarest zombies - it has very high health, and looks like a red skinned colonist with no shirt and red glowing eyes.The yellow eyed zombie - this type of zombie is less often seen and has about twice the health of a common green, it's defining feature is it's glowing yellow eyes.The common green shirt zombie - the weakest and most common among the assailants, easy to take down but a crowd of them can easily overwhelm an unprepared colony.Zombies have several variants ranging in colour and health points, their damage is however identical all around - 2 hits to slay a colonist.

However, zombies do not die at daybreak, so it is advised to keep guard at all times against the ever growing horde. Zombies typically spawn at night, unless the 'daytime monsters' feature is enabled (in which case they spawn 24/7). This includes underground and underwater. Zombies can spawn in any 1x1x2 space as long as it is not in your colonies 'safe zone'. The current colonist to zombie ratio is unknown, the main difficulty of determining that is the fact that a random amount of zombies spawn naturally, but the closest estimated formula is - (number of colonists)*2.

However, having no colonists doesn't stop the zombies from spawning. The amount of zombies depends on the amount of Colonists. The zombie spawns at night and slowly lumbers towards your flag, eating all of the colonists in its way. Zombies are undead humans closely resembling the appearance of colonists, with the most noticeable differences being a different colour scheme, glowing eyes and the absence of shirts on some of the zombie types. The Zombie is currently the only Monster in Colony Survival.
