Every so often a city may have an event happen, such as disease outbreaks or vermin infestations.

Some city events can solve themselves if the basic necessities are available.

If a city is managed well and has minimal issues, these city events should never happen.

Event Types

There are currently three events that can happen in a city.


Disease outbreaks can occur randomly in cities, the chance of this is increased if the resource zone is overpopulated or the city has a lot of unemployment.

While a city is diseased a number of citizens will die each city cycle.

To cure a city of disease, antitoxins are necessary. Each city cycle the city will use some of the antitoxin in storage. The lower the quality of the antitoxins, the more is needed, depending on the "level" of the disease. The city will show in the city reports how many antitoxins are required to cure the disease.

Passengers loaded from a diseased city will carry the disease, giving the potential risk of spreading the disease to other cities.

For details on how avatars are affected by disease, see the Health#Afflictions page.


Infestations are caused by vermin. The vermin will consume large amounts of food each city cycle.

Pharmaceuticals are needed to kill them off. If your city has an infestation, the city reports will tell you how many pharmaceuticals will be needed to kill the infestation and what quality it needs to be.

Should you lack of the required pharmaceuticals, infestation can be dealt with alternatively by starving off the city. This is dangerous since it will start to kill citizens too, if carried on too long it can lead to decay.

All pharmaceuticals will kill all infestations, but same or higher quality drugs will clear up the infestation faster and more efficiently.


Poison can occur when a city is staving or decaying. It is cured by antidotes.


  • The original implementation of city events that was added on April 28, 2011[1] caused the diseases and infestations to be way more powerful and devastating than intended. Due to the massive uncontrolled chaos of this, many empires fell, and this situation caused the sudden end of the Pan Galactic War.
