I didnt use a gas attack. I used a virus which consumes all organic material. It's baically the strongest ground weapon I have. It doesnt matter if you can inhale toxic gasses... these things eat everything. But to balance it I made it so I barely have any of them. This was more a way to show your species, which opened hostilities, that we will go to great lengths to ensure victory. And I left you with the option to reconsider if you want to fight a war or not. This action was just to show off my doomsday weapon... which is totally original and in no way inspired by Warhammer 40k...
