Typing of the Dead: Overkill Filth DLC out now, includes phrases like "spunk fountain"
Typing of the Dead: Overkill's latest DLC release is called Filth, and includes "terrible innuendo, outrageous insults and even some slurs in Polish". Looking through the screenshots below, it's entirely possible that you could construct innocent interpretations to most of these phrases if you tried really hard. I'm not sure why you would.
The DLC will set you back $3 on Steam.
Thanks, Shack News.
