its called Pandemic 2, ive been playing it for 3 days straight and i cant beat it
basically you need to infect everyone on the planet with your disease then kill everyone by enabling special features
but the world will start to make a vaccine to stop you, so the race is on!
let me know if you finish the game, tell me how you did it
