Plague Inc 2

Game description:

If the mankind was about to die, how would it be? Perhaps we’d got infected with some mysterious virus nobody knows how to deal with? Maybe it would even turn us into zombies? You can achieve that and much more in your secret headquarters where you’ll be putting together a formidable bacterial weapon to wage the final war of our race. Your goal is to kill everyone and it doesn’t matter how exactly you do it. Just know that humans won’t give up without a fight. You have to be a cunning strategist to pull it off!
