Chen Stormstout's brewery has been overrun by the Hozen and Virmen. The object of the dungeon is to reclaim his family's heritage and of course, his beer.
There are multiple sections to the dungeon:
The first involves encounters with the monkey-like Hozen, who are partying and being nuisances.
The second section has to do with fighting the Virmen, who overtaken the Brewery in massive numbers, eating everything they can get their paws on. After wading their way through the droves, players fight Hoptallus.
In the third and final section, players encounter Alemantals for the first time. These are elementals formed entirely of beer. Yan-Zhu the Uncasked is the final boss.
