I was not a big fan of the Headhunter packs in general, but I will admit there fun, even if they are really short. In my opinion Son of the Crawmerax is one of the longer Headhunter packs, and thats a good thing considering most of them are really short. In Son of the Crawmerax, you take on a boss based on the original Crawmerax the invincible from the first Borderlands game with a chance to get a Crawmerax head!
