The mutation allows The Spitter to spit vile acid forming a skin corrosive puddle on the floor, any Survivor that remains in contact with the acid receives damage over time, increasing in effect the longer they remain in contact with acid. Without a doubt my personal favorite from the new Special Infected, The Spitter has the ability to turn a perfectly calm survival situation into total chaos and anarchy. For the fourth part of our Special Infected guide we explain the tactics and skills needed in order to play a Spitter effectively.
