WP - "Infection 2 Bio War Simulation is the sequel to Infection, which is the popular kill-em-all disease-spreading simulator that takes a bit of influence from the original Plague Inc. Like the first Infection, you use DNA to purchase upgrades to your pathogens, but unlike the first Infection, there is now a premium currency in the form of gems."
WP - "Infection 2 Bio War Simulation is the sequel to the massively popular Infection Bio War. It's an extremely quick follow up to the original, which game out less than six months ago, but there's so much different in this (admittedly similar looking) game as to warrant a sequel. It's more difficult, for one thing."
WP - "Infection 2 Bio War Simulation is all about the destruction of humanity by means of biochemical warfare - or at least, how God would do it, since it's more of a "God Mode" game than anything. Like most good iOS games, this one contains a TON of unlockables."
WP - "Infection 2 Bio War Simulation is the sequel to the first Infection Bio War. Currently it's on the iOS platform, but expect an Android version to come out fairly soon. Infection 2 appears to be the same as the first one, but after a few quick play throughs, it becomes obvious that there are fairly significant gameplay differences."
