1.Well I haven't played on expert yet. If mainly just been messing around on verses.
2.Witch: Sure the tank is tough but the witch only needs to hit u once to incapacitate u, and for some strange reason the horde attacks me right after the witch dies.
3.Assult rifle: fastest reload+rapid fire= best gun(to me anyways) I really only like it cause if I reload when Im swarmed by the horde I can just melee them and its already reloaded
