Kite like a man achievement

Solution 1:

alt text "Kite Like a Man - Kill a tank only with damage from the original Survivors."

It's an achievement you can get only in "The Passing".

On the finale, the survivors from the original Left 4 Dead are helping you with shooting infected. The point of this achievement is to have them kill the tank, and them only shooting him.

Solution 2:

One of the easier ones. Gnoupi summerized it best. Just one addition:

Draw the tank to yourself and run around the generator until he dies. If he attempts to throw a rock, just stay right behind the generator and crouch.
