Being a killer is not as easy as it seems because in this category all your enemies that you will find in these killing games are not stupid and they will not go down easily, unless there is so many of them that their skill does not matter. Have some fun taking all of them at once and showing them that you are a true killer. Use various weapons that you can pick from the ground or that you can purchase from the shop in order to become a force to be reckoned with.
Have a great time taking all their lives knowing that they deserve it as they pose a threat to the citizens or to mankind. Aliens, monsters and zombies will be here and you will be there also to take care of the situation no matter the cost.
