Source: The Andromeda Strain
Location: Near space, Arizona, and the Wildfire installation
Threat Assessment: 8. A constantly mutating lifeform. Andromeda can be incredibly lethal causing instantanous clotting in most humans. It has also mutated to forms that eat plastic. Andromeda is a crystaline lifeform that grows best with an infusion of pure energy. Do not add with nuclear energy.
Limitation: Doesn't grow well in some PH environments. Doesn't like pure oxygen.
Personal Note: First film rocked, TV version sucked.
