Plague Inc: Evolved - Chemical Weapon Theme

Hello all, Here is a theme about a Chemical Plague, but more precisely Chemical Weapons . Sarin, CycloSarin, Mustard Gas , Phosphorus , VX Gas ... All these weapons are terrible because of symptoms and fear shock they do . So I wondered if a Chemical scenario was available, but I prefered to directly upload this theme :D I think I’m good with this theme :D Waiting for your comments :) Enjoy !
