disaster: Toxic fallout

[sacred hollow]

it lasts around a in-game day and will fade eventually as this would only cover 1 city at most but npcs will go inside as quickly as they can, alright so if your not wearing a gasmask you take poision damage until you go inside...though npcs have 75% chance of getting poisoned or 25% chance into to turn a mutant... mutants have passive regen and cannot hold weapons, they are hostile to everyone outside. luckily they die shortly after the fallout clears

note:this would be a rare disaster

Streets of Fallout: New Vegas
