This Guide Is Full Of Tips And Pointers For Your Average Zombie!
1) One of the most important things to remember is - don't keep trying to "eat" the same person, create some friends (kill other humans) and try again.
2) Shift will be your best friend, it gives you a very useful speed boost.
3) Never "Back Off" if a human is shooting at you, be relentless
4) Remember that on most of the maps, ammo is quite limited for humans.. use this to your advantage and remember that if a human kills you with a gun, they are still using precious ammo
5) Humans are always weaker in the beginning, when have not collected any weapons.. later in the game they can become quite powerful.. be sure to rush them if you can!
