Zombie Island Escape

You find yourself on a set of islands infested with Zombies. You must fight you way through them to find the button to escape. Rumor has it that you are not the only people on the islands. 

Starts off nice and easy, but gets harder and harder. You must kill zombies to get gold and ammo. Use it all wisely. You can get better guns as you progress through the islands. Find the protected button. You never know where an enemy lies.

Solo=almost impossible
Duos=very difficult
Trios=recommended
