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.
Similar to Nano-Virus, the Bio-Weapon is a powerful yet artificial engineered entity. Seemingly behaving like a Virus, Bio-Weapon does not feature escalating devolution costs nor excessive mutations from DNA fragmentation. A key feature of the Bio-Weapon is that its lethality will increase passively throughout the game. By default, the Bio-Weapon has slightly higher infectivity than usual, and is better suited to rich countries than average.
Bio-Weapon's innate lethality increment occurs randomly on a daily basis, eventually going exponential if left unchecked.
- Gene Compression 1-3 - Extends the delay between lethality increments.
- Nucleic Acid Neutralization 1-3- Resets exponential lethality growth to base.
- Deactivated Modified Genes 1-3- Reduces lethality.
- Unlock Annihilate gene - Greatly increases infectivity, severity, and brings forth massive lethality boosts.
