The new content patch will introduce a marauder boss called Dante the Teaser, as well as a new game mechanic called Occupations. Occupations bring a bit of structure to the game's traditional sandbox skill-building system, and were designed to further roleplay opportunities, introduce new player goals, and allow for progression via regenerative items.
Players will need to perform collection and processing tasks specific to each of the new occupations (examples of which include Butcher, Magnetic Cartographer, and Florist) in order to obtain and progress with the new regenerative items. The items then act as temporary stat boosters when consumed. You can check out all the details on the official forums.
