It would be cool if this virus turned people feral. Like, if it fried their brain and they turned into people who can only think about tearing people to pieces with their own hands and teeth. Like zombies, but alive. I don't think I've ever seen an NRP where nations have to deal with something like that. It'd be fun to see the infection spreading towards someone's borders, forcing them to prepare for mindless flesh-eating infected about to flood their country.
