and witch. each one of these special infected have special attacks and unique abilities that will be used to slow you down, drain your health or take you away from the group.
in versus mode, all these characters can be played by other players except the witch. the witch adds an especially scary aspect to the game due to her image and ability. you can tell when a witch is nearby because you will hear a young girls voice crying. if you approach her too closely she will growl at you. if you have the unfortunate luck of running into one before noticing where she is you will completely kill you
