Infection Z

The Infection Z was a virus which could cause people to mutate and become creatures known as 'Necromorphs'. It spread via bites.

Origins
Infection Z was created by Victor Pradeux, a scientist working for Atton Korso who has gone mad after getting sent back in time by the separatist wormhole simulator device. Many Alliance and Separatist worlds are infected, and the factions make peace to fight the undead instead of each other. Howard Tarkin uses the plague as an opportunity to bring reforms to the New Separatist Confederacy.

Symptoms and abilities
Infection Z can reanimate corpses and mutate them into cannibalistic monsters. The infected grow tentacles on their back in a matter of minutes after their infection. Necromorphs can destroy droids and bite humans to turn them into one of the mindless mutant zombies. The first symptoms of the infection are headaches and extreme pain. After the pain comes minor physical changes, such as loosing teeth or nails. The final stage is major physical changes, such as growing new limbs. The infected looses his mind at the final stage.
