Zombeast Game Tips for your perusal if you really wanna progress and if you like this game.
How To aim and Shoot Zombies
The game does most of the aim automatically. All you have to do is move the game joystick on the left to move the character, which is on the left and aim automatically pin points to the zombie closest to your aim. Try to shoot only when your aim turns [GREEN].

Shooting Zombies
The shooting part depends on the weapon you have. Such as Shotguns are good for eliminating the usual basic zombies.
Whilst, a pistol is good for the big zombies.
Though all the weapons will do damage either way to the zombies available. But each weapon does a slightly different damage to different zombies.
Pick Up Weapons and Ammo Quickly
The game gives you more bullets at some point on some if not most of the level your playing.

How To Avoid Getting Caught By a Zombie and You More Time
You can avoid getting caught by moving backwards. The way it works is, the game gives you the opportunity to move backwards during a mission in any visible direction.
This gives you time to reload and switch weapons to use for the specific type of zombie that might appear or that is coming towards you.
Shoot when your aim is Green

It makes sense to wait for aim to go green so you know you have a good shot and can do more damage to the zombie.
But there at times when you don’t have time to wait to go green so you just have to shoot and the switch weapons when reloading.
This is a good trick to help beat zombies running towards you.
Grenades (Zombeast Game Tips)
Firstly, only use grenades when you have a huge amount of zombies ahead and you want to move through them quickly.

Then it doesn’t hurt to throw a grenade at them and shoot the rest.
Doing this will clear a path for you.

Reload After 2 Shots (iF Possible)
As a trick I realised if I reload quickly whilst moving backwards, after couple of shots, I have a better chance of keeping zombies dead at bay rather than them getting too close to me and then I panic as am trying to reload which might end up being a little too late.
So its always good to reload on time especially when zombies are far away from you.
