Zombs io begins by choosing a place to build a base. The base will be located where you build the treasury (gold storage). From this moment on to the nearest and every subsequent night you will be attacked by zombies.
The next step will be the construction of gold mines for gold mining. Wood and stones are obtained from trees and quarries respectively.
Defensive fortifications and towers will help fight off zombies.
Having accumulated a sufficient amount of gold, you can upgrade the treasury and get the opportunity to upgrade other buildings.
