General Information

The Bio-Weapon is a genetically and biologically engineered and modified virus that was accidentally released from a laboratory. It is the final Standard Plague available in the game. It is quite similar to other diseases, primarily the virus standard plague type in physical appearance and in shape and size. However, unlike the previous plague types, the Bio-Weapon will grow progressively more lethal over the course of the game, making it more likely to kill off one's hosts before they are able to infect more people and causing quick detection. To win, the player must use the disease's special abilities to lower the lethality in order to avoid killing too many hosts too early. This quirk makes the Bio-Weapon ideal for speed run strategies, similar to Nano-Virus (cure starts at the beginning of the game). The interface of the Bio-Weapon also very strongly resembles an RNA Retrovirus.

By default, the Bio-Weapon has slightly higher infectivity than usual, and is better suited to rich countries than average.

Special Abilities

Gradual Lethality

Every in game day, the game will roll a random chance for the Bio-Weapon to increase lethality naturally. As the game progresses, the chance of lethality will increase exponentially. Nucleic Acid Neutralization will reset the exponential growth rate to zero, Gene Compression reduces lethality growth, Deactivate Modified Genes removes set amounts of lethality.
