An anthrax warhead, anthrax bomb, or anthrax missile is a biological weapon developed by the Hurian Federation as a detterent to foreign invasion and to cause as much collateral damage to enemy cities as possible. The weapon itself is extremely simple in the fact that it is only a delivery system, which carries a set amount anthrax that will be scattered across an enemy city or position, and carried across the wind, infecting and killing many thousands, and with new upgrades, possibly millions.
