You mean this? But, if you have a auto shotgun in your hand you might want to try it out. or even get Cr0wned Achievement. I personally love Boomer and Smoker. Especially in No Mercy campaign Last chapter: Roof Top. where you don't need to face the Survivor at all. Just give 'em a bile of vomit from below and smoke 'em to the death or drag 'em below so one of the survivor are helpless on the corner of the building.
