This build focuses on killing special mutations very fast with little effort, as the DPS you can play Jim or Walker (Personally prefer Jim for his ADS and weakspot damage as well as his passive 25% damage.) Your main goal is to get a hard hitting rifle in your hands such as the Ranch rifle or Scar if possible since they have the highest base damage, If you don't want to use overkill, Mag carrier, and admin reload, you can shift the build a bit and put in reload speed and give yourself some damage resistance and health.
