I kill the most zombies, but take far more damage. Is there any way of encouraging the AI teammates to take point? Last night, I played Death Toll for the first time, and came upon a witch in the drain pipe. There was no way around her.
I tossed a pipe bomb at her - she took no damage and didn't notice me. I had to fire on her, and was brutally slain.
Also, is there a way for AI survivors to toss pipe-bombs or molatovs?
