You think we will see rules for chemical weapons? Biological weapons?

I imagine it would be template based, which would be different. You would have a center square with takes the larger hit (2/Health) and each adjacent square would take a lesser hit (1/Health). and it would dissipate or move turn by turn.

MMMM take some thinking.

It certainly seems like they would use them. If the Nazis had invaded the UK, the brits had the plans in place to gas them on the beaches.
