Yeah, that game is extremely hyped up at my job too. Everytime I ask my iPhone fanboy coworkers what they are doing on their phones, I usually hear "playing Plague".
Officially sent from my HTC EVO 4G LTE using Android Forums.
Yeah I saw that one too but the description led me to believe it was more of a real world interactive game:
"Infections get transferred by players coming within proximity of each other in the real world. Players infected with your virus will carry it and infect more players. See how quickly your unique virus spreads!"
