I was playing no mercy on easy (online) so I could get the achievements for not healing and not disturbing any witches. ANYWAYS, we were at the top floor right before the penultimate safehouse and I got jumped by a smoker, but my teammates were too busy dicking around and killing common undead to help me before I got incapped. Then, one of the AI survivors decided to heal me and I couldn't stop him from healing because L4D sucks. Oh, and there was a witch placed in an unavoidable spot right outside the safehouse door.
