I have flavor text for one of the nerve gases but I'm not entirely sure what to actually do for it, crunchwise. Here's VX-80.
Compared against CN-20...A relative newcomer, this modernized nerve agent is capable of long duration aerosol deployment. Fired as a ‘curtain’, iridescent clouds of this weapon can hang for up to six hours in good conditions, though high heat or precipitation can cut this down to under thirty minutes.
The agent remains active as a rule of thumb for up to 72 hours, with cases of cool shaded areas holding active lethal concentration up to 168 hours.
Any suggestions?Advanced non-persistent trinary nerve agent of Chinese origin. Vaporizes in pressures <2 bar, posing an inhalation and dermal contact hazard. Capable of defeating older filters, as it will not bind with the material.
Breakdown beyond effect range at about two to four hours. Byproducts are harmless, but potentially environmentally negative should CN-20 be deployed in heavy saturation.
Edit: Currently considering using Virulence for persistence, but not attached, or anything.
