Horde Pheromones
AbilitiesHorde leaders produce pheromones to attract zombies to them. Zombie hordes can be millions strong
Horde Vocalisation
AbilitiesHorde leaders attract nearby zombies with distinctive moans. Hordes can have hundreds of thousands of zombies
Hyper Salivation
SymptomsInflammation of the submandibular gland increases saliva production and infection rates
Hyperosmia
SymptomsThinning of the nasal epithelium significantly heightens zombie sense of smell. Increases severity
Insect
TransmissionsInsects susceptible to infection. Carriers increase infectivity, especially in hot climates and chance of mutation
Insomnia
SymptomsInability to sleep causes irritation and tiredness. Slows future research speed
Liquefactive Necrosis
AbilitiesReanimated zombies have partially liquefied internal organs which rupture easily. Reanimated zombies get combat advantage
Liquefactive Resistance
AbilitiesVirus denatures hydrolytic enzymes, slowing liquefactive necrosis and decomposition of the corpse
Lumbrical Hypertrophy
SymptomsSignificantly strengthens zombie grip making it nearly impossible for prey to break free. Severity significantly increased
Masticatory Tension
SymptomsMasticatory muscles become engorged, allowing zombie to bite through thick clothing. Severity increased
Mummification
AbilitiesA severely decayed zombie is able to enter a state of hibernation. Reduces rate of zombie decay, especially in hot countries
Naja Mortis
SymptomsMuscle growth around submandibular duct lets some zombies projectile spit at prey. Increases severity and zombie combat advantage
Peptide Surge
SymptomsGrowth hormone production triggers extreme metabolism of fat to build muscle. Enhanced strength increases severity
Photophobia
SymptomsSensitivity and pain when eyes exposed to sunlight. Slows future research speed but slightly reduces infection rates
Polyphagia
SymptomsCompulsive hunger forces continuous eating. Lack of hygiene increases risk of infection
Psychosis
SymptomsPsychotic episodes lead to occasional bursts of extreme violence which can be lethal. Increases infectivity and slows future research speed
Putrefactive Resistance
AbilitiesVirus prevents anaerobic microorganisms from digesting proteins - slowing decomposition of corpse
Regenerative Activation
AbilitiesActive ability enables neurological regeneration in the brains of infected corpses - effectively re-animating some of the dead
Regenerative Bio-synthesis
AbilitiesEnhanced neurological regenerative proteins allow corpses with severe head wounds to be re-animated
Rodent 1
TransmissionsHost range broadens to include rats. Increases infectivity, especially in urban regions and mutation chance
Rodent 2
TransmissionsPartial genetic activation causes rat packs to attack humans. Significantly increases infectivity, especially in urban regions
Saliva 1
TransmissionsVirus replicates faster in salivary glands - increasing chance of infection through contact with saliva
Saliva 2
TransmissionsVirus replicates directly in nasal cavity - significantly increasing chance of infection through contact with mucus
Segmented Genome
TransmissionsVirus splits its genome into smaller molecules - increasing the likelihood of a viable mutation during transmission
