Database

Extreme laryngopharyngeal reflux causes acidic saliva. Increases severity and gives zombies a combat advantage

Acute Encephalitis

Multiple inflammatory lesions in the brain cause severe neurological damage resulting in death

21DNA

Adrenal Surge

Mutation of the adrenal cortex causes adrenaline over-production, increasing alertness and aggression of zombies

Air 1

Virus bypasses alveolar macrophages in lungs to enter bloodstream. Increase infectivity, especially in arid environments and plane transmission

6DNA

Air 2

Virus can travel on dust particles. Increases infectivity, especially in arid environments and plane transmission

10DNA

Air 3

Virus replicates rapidly in aerosoled brain matter. Significantly increases risk of infection if interacting with zombie brains

Ambush Predation

Reanimated zombies often remain still - waiting for humans to approach them. Reanimated zombies get combat advantage

2DNA

Anabolic Boost

Surges of testosterone significantly increase muscle mass and weight of some zombies. Severity significantly increased

18DNA

Anaerobic Resuscitation

Infected braincells switch to anaerobic respiration. Lactic acid buildup is lethal and destroys higher brain processes and personality

Autolytic Delay

Virus slows release of digestive enzymes from cells' lysosomes - slowing decomposition of corpse

5DNA

Autophagia

Compulsion to bite or partially devour own body - typically fingers or skin. Increases infection rates

Autothysis

Explosive mix of hydrogen sulphide and methane collects inside zombie. Significantly increases severity and zombie combat advantage

22DNA

Bat 1

Host range broadens to include bats which are hard to detect. Increases infectivity and mutation chance

Bat 2

Partial genetic activation causes bats to mob and attack humans at night. Significantly increases infectivity and attacks can be lethal

15DNA

Bird 1

Host range broadens to include birds. Increases infectivity, land transmission and mutation chance

13DNA

Bird 2

Partial genetic activation triggers random bird attacks on humans. Significantly increases infectivity and land transmission

18DNA

Blood 1

Virus enters the circulatory system, blood is now a transmission vector. Poor countries particularly vulnerable

Blood 2

Virus can replicate directly in the blood stream, significantly increasing infectivity. Poor countries particularly vulnerable

11DNA

Bone Dysplasia

Increased bone density provides enhanced protection against trauma. Gives zombies a significant combat advantage

15DNA

Cannibalism

Extreme compulsion to bite and eat other humans - significantly increasing infectivity as well as lethality

20DNA

Cathemeral Shift

Stimulation of primary visual cortex improves vision in bright sunlight. Significantly increases severity

Cold Resistance 1

Pathogen evolves to withstand cold temperatures and climates

5DNA

Cold Resistance 2

Lower intracellular water volume prevents freezing. Increased effectiveness in cold climates

7DNA

Coma

Pressure buildup in the brain stem can cause loss of consciousness. Significantly slows future research speed but reduces infection rates
