Virus

Viruses are hostile microbes that damage the stem cell and infect friendly cells. Infected cells can produce a mixture of more viruses and toxins.



Behavior
Viruses move toward the stem cell along the shortest open route. If blocked, they will immediately attempt to infect the blocking cell, turning it into an Infected cell. There is also a small chance that a virus attacks any friendly cell at random. Infecting a friendly cell "expends" the virus (it dies in the process of infection).

Variants
There are currently three known variants of virus; El Bolador, Col. D Virus and I.N. Furenza.

Col. D Virus
Slow moving and not particularly dangerous, the cold virus can be a much bigger challenge when combined with other infections.

I.N. Furenza
In many respects similar to Col. D, influenza causes much more dangerous infected cells that last considerably longer.

El Bolador
The deadly lethal ebola virus is fast moving and causes short lived but virulent infections.
