sf guide lines for leveling up (for begginers)

First   you should always play the horror mode,this will allow to battle with zombies,the target of this mode is you should kill the host zombie or the TANK of the zombies,but beware sometimes you could be the host zombie of the mode,if you will be the zombie host of the game your goal is for you to make all players into a zombie in order for you to make them zombies you should kill them,if you want to know what weapon to use in the horror mode the weapon  you should use is the machine gun ,the machine gun lets you kill zombies easier becuase of its strenght,and that is all you need to know to level up easier.thankyou
