dude...i figured maybe id buy it and thered be a screamer, or maybe it really WOULD be an awesome upgrade. but no. I dont even get to buy it. ARGH!!!!!
Omg, make this game more realistic! U cannot spot a disease with no symptoms! no government is going to close anything down if the disease doesn't even do anything! and another thing: the whole "luck" factor is BS! u ought to somehow be able to kill off all of humanity EVERY TIME, if u play the game right.
i have to agree with dragonman. the game is fun, but its just too easy. the training is always the same animals, but it should get progressively harder, or be randomized. all in all, a fun game, but it gets a little monotonous. 3 stars
