Let's review Zombie Hunter King Game on android.
The game here is one of the simple games you can think of. Just point your sniper at the target and hit the button. So each level you have to kill some specific number of zombies. And the situation gets harder because you have to rescue some people or kill before the zombie gets closer.
Here's one level that you can check out to get the idea on how the game is in such context.
Another level you can check out for more explanation on what type of targets you are going to complete here in the game. You may find some scenarios pretty cheesy if you ask me. But yeah it;s a game and you have to play what you are given.
Graphics of the game is good, it could improve but for that much RAM and the graphics requirement, anyone can play the game. It's also simple as you are not forced for something or have too much to ask in that context.
