Gun Zombie Gun

It is the time of the Wild West, but unfortunately, a terrible disease spread, killing half of the people.  Soon the dead rises and it was causing all kinds of trouble for the living.  But, not for the cowboys as they see this as another opportunity to make money.  They are paid to kill these zombies. The game is played via mouse and you just need to kill all the zombies in a level to advance to the next.  There are cases, wherein the zombies will be hard to reach so you need to look at the surrounding and use anything that you can use to reach the zombies.
