Recently found this game online, and I can honestly say, I'm addicted.

Instead of most normal zombie games, where your main objective is to kill the zeds, this game's objective is to spread the infection. You start out In Africa, infecting small towns, then gradually move on to larger cities, like Cairo. Eventually, you spread it all around the world.
I can't stop playing.
I always sent the col. and tank, then used one click near the highest concentration of fat people which spread the virus pretty well. I used MJ when the zed numbers began to run low.
But yea... towards the end it got a but too easy...
Wounds are for the desperate, blows are for the strong
Balm and oil for the weary hearts all cut and bruised with wrong
I forgive thy treason-I redeem thy fall
For Iron-Cold Iron-Must be master of men all!
