Aggression is a symptom in the Neurax Worm DLC. It causes hatred and violence, particularly towards authorities and uninfected people.
Frozen Virus Version
There is a very similar version of Aggression in the Frozen Virus scenario, with the description "Confusion and immaturity results in lethal primal aggression towards others. Cure progress significantly slowed".
- Countries affected by this symptom may legalize public fights, leading to increased lethality rates. Sometimes, countries may even hold gladiator fights and/or Death Races.
