Is their a fourth special infected in left 4 dead 2

Well, the original four are the Boomer, Hunter, Smoker and Tank.

They have added three more.


The Charger, who can knock you off your feet.


The Spitter, who spits infected mucus in an area, and you take damage when in that area.


And the Jockey, who can jump on Survivor's backs and steer them into places, like other infected.
Well not really theres another infected called the spiker : throws debris of his back
and yes his back has spikes on it but its not confimed.the charger can dash and all but he is immune to bashing so rifle butting wont work.So i suggest you trick him off precipice.
THE Spitter can spit and all but it has really low life and it has very little combat skills to resort too
the jockey can jump on your back but... it would have to crouch and wait for you to come to get on your back. It can easily be killed in combat.
And finall y the witch now called the wandering witch she can wander around and itll be more diffucult to get past her. her health is 500/1000 that's a...............lot
but valve is still toying with the fourth new infected well just have to wait till it comes out
