Vespene Rasp is a respiratory disease that afflicts Terrans in the Koprulu Sector.

Two years after the process of Vespene Gas refinement was discovered, a condition commonly known as Vespene Rasp began to affect miners and SCV operators. Due to the unstable nature of raw Vespene, any Terran with prolonged exposure develops Vespene Rasp if not treated immediately. Raw Vespene damages the lungs of victims, before chemically reacting with compounds in the blood that eventually accumulate in the brain.


Vespene Rasp comes in four stages. The first three are treatable, however, the last has only two known cures.

Stage OneEdit

About 70% of miners got this before air-tight SCVs were created. Usually occurs after two to three weeks of initial exposure. Not the most serious stage, but none the less inconvenient.

  • Coughing, wheezing, and difficulty speaking
  • Minor seizures
  • Headaches
  • Blurred vision

Stage TwoEdit

Occurs in 80% of people who were not treated at stage one. Not life-threating, but it is much shorter with a time interval of 3-4 days. It is most recommended that the infected person be treated immediately.

  • Rapid coughing with green phlegm
  • Chronic seizures
  • Migraines
  • Loss of coherent speech
  • Sores on mouth
  • Hair loss

Stage ThreeEdit

Occurs in 100% of people not treated in the first two stages. Extremely life-threating with a time interval of 2 days. This is the last stage where there is any hope of curing the victim.

  • Bloody cough
  • Hallucinations
  • Loss of speech
  • Dementia
  • Sores appearing everywhere
  • Minor skin loss
  • Progressive bleeding

Stage FourEdit

The final stage of Vespene Rasp. The accumulation of toxins in the victim's brain have damaged it beyond repair. All higher level mental functions are irretrievable. It is highly unpredictable due to the similarities to stage three.

  • All the symptoms of Stage one
  • Cannibalism (Resident Evil: Tyrant-virus)
  • Medication: 3.8 - 9 mm of Lead or Uranium-238
