Create your own disease and destroy the human population in iOS infect-'em-up Pandemic 2.5

Indie development studio Dark Realm Games has just released an iPhone and iPad title called Pandemic 2.5, which allows you to create your very own disease before unleashing it on the human population.

This refined Flash game tasks you with creating a deadly disease by choosing from one of three different infection classes - bacterial, viral, parasitic - and splicing in specific genes to form your own special concoction.

Once created, you can't simply dump your new affliction into the world. You'll have to operate "below the radar" if you wish to avoid quarantines, curfews, and vaccine-creating scientists, and infect all 33 regions present in the game.

You do, however, want to take full advantage of riots and other disasters, which are perfect for spreading your illness.
