Enter the world of Cemetery Of Skeletons, here you will have to fight against hordes of skeletons to save the earth. Armed with a rifle you can shoot and kill the skeletons while trying to complete the level by reaching the checkpoint. You will also have to be careful: if you enter the field of vision of a skeleton it will start running and chasing you. If there are few of them they are manageable but too many can be a problem. Play using keyboard and mouse, shooting with left mouse click. Good luck and survive
