DeadLand Runner is the best zombie game in the Google Play Store.

You are in a zombie world. You have to run for your life to survive.

You have to complete missions and survive as much as you can. Your mission is to run and collect coins as much as you can.

Your character is not very powerful, but he can fire his crossbow to kill zombies and werewolves. As you play, you'll be getting coins that allow you to buy new weapons (try to get the wonderful STACA-Matick "Betty") and unlock new characters with better skills like Health, speed and jumping ability.
