Mud Crabs Swearing In Rimworld
Replaces the urgent letter sound with the swearing mud crab sound from Skyrim.

Save game compatible of course.
Works the same as the "No God No" mod by Azazel which can be found here: http://steamcommunity.com/sharedfiles/filedetails/?id=868194038&searchtext=No+God+no
