Rainbow Six Extraction Nightmare Fog event introduces a terrifying new limited-time mode

Rainbow Six Extraction players can now enjoy the new Nightmare Fog Crisis event, introducing the new deadly Neurotoxin level, horrifying hallucinations, and a new objective. 

The Nightmare Fog event is the latest limited-time mode where players must work together with their team to fight through the Containment Zone. But this time around, the Containment Zone is clouded in a new deadly fog that exposes operators to a fatal new Neurotoxin. The longer players remain in the fog, the higher their Neurotoxin level will increase, introducing new deadly and debilitating effects.
