this question comes to my mind... i didnt find the aswer..
what is the speed of the zombies?
only shamble?
walk normally?
can run?
athlets everytime???(dawn of the dead...)

thanks

Not that i am in my right to answer but from my understanding they come in all speeds depending how well feed they are.
Ie. you have regulars not in a large pack of zombies or possibly lone wolfs - not so much feed.
Then there is larger packs where you have a leader shape with devious tactics for you to aloud..
Biggest threat out there though is the Brotherhood, you dont want them on you tail..

But in short they come in all speeds, the more speedier the more well feed.. also to note weather conditions can make them nimbler or less nimbler to the frozen ones underneath the snow, which is a trap.

But dont forget these conditions affect you to

As i say to myself when i write, aim low, double tap =P

Edit: For god`s sake dont forget to double tap unless you wish for nasty surprises

thanks for the answer

double tap is an important thing i know
