ZombYD io is a very original survival shooter, where you can take a break for a minute! However that won't make zombie population less :)
How to Play
Main goal is to get the most money. The only way to do this is to kill zombies, actually it's the only thing to do in this game! The more experiences zombie hunter you're the more zombies will attack you.
As you kill zombies you receive new levels. Every level brings you new weapons. Ammo in the Zombyd io is infinite, no worry. However it takes a while to reload, so keep in mind that you need a safe couple of seconds to reload the gun.
If you step into the center of the map the game freezes. Zombies no longer move and new ones don't appear. Unfortunately you can't shoot while inside the circle. Take a break and step out of the circle to start exterminating monsters again!
